How Birding Can Save the World

Before I get into this, here is a little bit about me. My pronouns are he/him. I am a citizen of Cherokee Nation and white-presenting (that is, I look like a white male).

1. Everyone likes birds.

Everyone. Regardless of age, gender, sexual orientation, race, socio-economic status, political orientation, urban or rural background, if you asked them if they like birds, they’ll say yes. They may complain about a few problem birds that crap on their car, but in general, people will say they like birds. And they put their money into it. The public spends about as much on backyard bird feeding as it does on movies and television. Birds are beautiful. They fly. They evoke freedom and encourage us to dream.

2. Birding is a pathway to greater environmental knowledge and belief in science.

To get to know birds is to learn about migration, seasons, weather, ecology, habitats and threats to habitats. To watch birds is to see the human/nature interface in bright daylight – the dog that chases the endangered Snowy Plover, the development that removes the woods on the edge of town, the cat that kills the sparrows that migrated here from central Alaska. Birders overcome Nature Deficit Disorder. They become ecologically educated, understanding environmental issues.

3. Birders support environmental causes and the fight against climate change.

In general, birders are environmentalists. Cooper et al (2015) found that birders (and hunters) were “4 to 5 times more likely to engage in conservation behaviors,” such as supporting environmental causes. They concluded, “Strategies that include programs to encourage both hunting and birdwatching are likely to bring about long-term gains for conservation.”  

4. There are far fewer birders than there should be.

There could be a lot more, but certain demographics are underrepresented in the birding community. This includes non-white ethno-racial groups, younger people, and less educated people.

Ethno-racial categories

In their 2021 paper, Racial, ethnic, and social patterns in the recreation specialization of birdwatchers: An analysis of United States eBird registrants, Jonathan Rutter et al (no relation to Jordan Rutter of Bird Names for Birds) analyzed a survey of 30,000 eBird users. That paper, especially Table 3, is the basis for the graphs presented here. Note that the eBird data comes from 2016-17 and the US population data comes from 2011-15. There has almost certainly been an increase in diversity in both datasets since then, especially the eBird data. In 2016, eBird was still fairly limited to certain social circles. The number of eBird users has nearly doubled since then. A new survey would show far more diversity.

Pie graphs of US adult population and eBird users by ethno-racial group.

Going back further, in 2005, John Robinson found that, while the majority of Blacks expressed a high level of interest in the environment, very few participated in birding (or other outdoor activities) and very few had ties to environmental organizations. He famously said that “the average bird watcher will meet no more than two or three African-American bird watchers over a 20-year period.” That has changed.

This underrepresentation has been correlated with other outdoor activities, as well as membership in conservation organizations – and especially in leadership – more on that below.

With respect to birders, are we talking about backyard feeder watchers or avid listers? Rutter et al dived into this, what is termed the degree of “specialization” – how avid and dedicated one is. They asked questions such as: How often to you travel from home to look for birds? How often do you use eBird? Do you own a scope? How many species can you identify by ear? They found no effect on specialization by race. In fact, race, age, gender, knowing a close friend or relative who is a birder, income, and education combined only “explained 6.7% of the variability in how central birdwatching was to respondents’ lives.” No matter what your background, once you start, you are equally likely to head down various paths of birding obsessiveness.

The huge racial divide then, occurs at step one, the decision to start looking at birds. After that, the birds do the rest. Rutter et al concluded, “Future efforts to diversify the birdwatching community, therefore, may be most effective if focused on increasing initial participation rates of underrepresented groups.”

Gender

Nearly every study shows there are slightly more female than male birders. This holds across all ethno-racial categories. (Note, this data, collected in 2016-17, makes no reference to non-binary or refuse-to-state responses. The total in the graph sums to 99.9%. I don’t know if this is rounding error or reflects alternative responses, or if alternative responses were removed from the analysis.)

pie graph of male and female birders

Regarding degree of specialization – how avid and dedicated and experienced they were – men scored higher than women on these questions, but only by a small margin, just 1.7 points on a scale with a median score of 17 (e.g. perhaps men averaged 17.7 and women 16.0).

While there are lots of women birders, and they are nearly as specialized as men, they are far less likely to be in leadership. Most prominent birders – the ones who lead Christmas Bird Counts, serve as eBird reviewers, serve on state or national bird records committees, work as bird guides, speak at conferences, write field guides, etc. – are white men. (A notable historical exception: the first field guide that popularized birding for the public was written by Florence Merriam Bailey in 1889.)

Looking at the top 10 or 20 birders on eBird – in any state or region for any given year – women are typically only represented by a few individuals, whether looking at number of checklists submitted or – a decidedly more competitive and obsessive measure – number of species seen in a given year.

The dearth of women in leadership continues across environmental organizations in general. In 2015, Dorceta Taylor looked at 324 such groups, finding that “though females exceed males on the staff of environmental organizations, women are underrepresented in the top leadership echelons of the institutions.”

In academia, however, change is afoot. While ornithology professors are still mostly men, this varies across universities. The new generation is far more diverse. At the 2023 AOS annual convention, women won 19 of the 23 awards. Additionally, diversity, equity, and inclusion topics were prominent among the papers and presentations.

Age

For all ethno-racial categories, birders (in green) average older than the overall population (in blue), with the breakpoint generally in the upper 40s. Again, this data is dated, and more young birders now avidly embrace eBird. White birders skew older more than any others, and have, in proportion to their population, the fewest young birders and the most older birders. Asians are at the other end of the spectrum, with the most young birders as a proportion of their population. Asian young people are more than twice as likely to take up birding than their white counterparts. Latinx, Blacks, and Native Americans are between, in that order, with the Latinx closer to the Asian graph below. 

graph of birders and overall population by age categories -- for white and Asian birders

The take home here is that there are many potential birders among those under 45 – and even more under 35 and yet more under 25. And young people of color are more likely to take up birding than white young people.

Education

Relative to the overall population, birders are extremely educated. One big caveat here: It could be that there are plenty of less-educated birders, but they just don’t use eBird as much. The survey showed that nearly half (48%) of the 30,000 eBird users surveyed had advanced degrees, compared to just 12% of the other whites (age 18+). This is even more true among birders of color. Latinx birders were 10x more likely than other Latinx to have advanced degrees. Blacks and Native Americans were 6x more likely. A person with an advanced degree is 13x more likely to be a birder than a person without a Bachelors.

education level of birders and general public

The October 2021 issue of Birding magazine explored the least birded counties in the nation, based on the number of eBird checklists. Of the bottom 20, 18 were in Kentucky, Mississippi, or West Virginia, all small rural counties. Sure, they have fewer people than a major metropolitan county. King County (Seattle) generates many times more eBird checklists in a single day (about 700/day) than these counties have in the history of eBird (all with fewer than 100 checklists total). At the same time, I wonder if these low rural county birding rates are partly explained by the education graph above.

Hunting is popular in these areas. 60% of duck hunters are from small towns or rural areas. Surveys of duck hunters show some similarity to birders (e.g. predominantly white), but a different trend regarding education. While they still skew slightly toward more educated, their graph mimics the general population fairly closely.

As someone who learned to bird from my father’s duck hunting blind in a small rural county, I can also assure you that plenty of lesser educated hunters and anglers love the outdoors and know birds pretty well. An advanced degree is not required for bird identification, and certainly not to be an avid birder. Lesser educated rural people could become birders. The take home here is that there are millions of potential birders among those who are less educated, and certainly among hunters who support environmental causes.

Income

Despite their exceptionally higher education level, birders do not earn more money than the general public. This is pretty consistent across all ethno-racial categories. If anything, birders earn slightly less. For example, 24% of the general public earns between $100K and $200K per year. Only 21% of birders do.

income level of birders and general public

To summarize where we are, there are three main demographic groups (which no doubt have some overlap with each other) that bird at lower rates: people of color, younger people (especially whites), and less educated people. While there have no doubt been significant increases in these groups since this survey was done, it is still clear that there is a lack of birders of color and women in leadership roles. This is where there are opportunities to grow birding and the environmental movement in general. And research suggests that knowing other birders is key to start birding.

5. Because underrepresented people are not included – and are actively excluded.

In recent years, there has been a rise in historically-marginalized identity-based birding clubs and ornithological organizations, a kind of alternative birding universe where people can experience birding in a closer-knit community with different social rules, expectations, and styles of communication than in larger white-male-dominated birding circles. Here are some of those groups (and a podcast):

  • In Color Birding Club – we strive to make the birding experience a positive one for BIPOC folks and their allies.
  • Anti-Racist Avid Birders – dedicated to making the outdoors—and birding in particular— accessible and safe for people who find themselves under-represented or unacknowledged in traditional birding communities.
  • Always Be Birdin’ podcast – aims to change the narrative of birding. How we bird, where we bird and who is birding. Join me as I go out into the field with BIPOC birding experts, novice baby birders like myself and nature enthusiasts.
  • Freedom Birders – a racial justice education project.
  • Melanin Base Camp – to increase ethnic minority and LGBTQ+ participation in the outdoors (more focused on adventure sports).
  • Feminist Bird Club – dedicated to promoting inclusivity in birding.
  • The Galbatross Project and Female Bird Day – focusing attention on the importance of female birds.
  • World Girl Birders – to find solutions and creative approaches to supporting women in birding.
  • Rainbow Lorikeets – the AOS caucus of the National Organization of Gay and Lesbian Scientists and Technical Professionals. 
  • QBNA (LGBTQ+ Birders of North America) – to facilitate communication among LGBTQ+ birders and their allies 
  • Frontiers in Ornithology – to educate and inspire youth to take their passion for birds to a higher level.

(Please let me know of more groups I should add to this list.)

There are also many local groups like the ones above, as well as for young birders. And there is Black Birders Week, supported by a wide range of organizations.

Here are some important essays and books on the same themes:

Dominant birding culture

Birding is a pseudo-academic hobby that can take on the vibe of a competitive academic department with a strict, though unwritten, code of behavior. As with any hobby, there is a whole lingo associated with certain activities, especially chasing and listing. Some of it sends subtle messages about how to be a birder, and what it takes to be an Alpha dog.

I drank the Kool-Aid for years. I thought these things were important to cultivate the right kind of birders. I was a gate-keeper. Now I realize enforcing a specific culture and birding etiquette can be a turnoff to new birders, especially those from different demographic backgrounds not comfortable navigating in white male spaces, much less a very specialized and potentially competitive environment. We are, after all, talking about enjoying nature here.

Let’s take one example. Among the cardinal sins for those seeking birding Alpha status is this: do not make an identification mistake in public. When I was a young birder, I loved public debates and discussions about golden-plovers and dowitchers, vireos and accipiters; that’s how I learned. They seem harder to find now – not the birds, the open discussions.

I was recently called “incredibly brave” by a teenage birder for publicly calling attention to a difficult id problem between a rare vagrant and a common species, positing that the bird may be the vagrant. The teen had already figured out the code. The bird, as the odds have it, turned out to be the common one. Later, people were thanking me for initiating the educational discussion online. I’m not brave, just jaded enough that I’m trying to care less about my reputation and am trying to model ‘learning in public,’ which is critical to learning about birds. If gulls and Empidonax flycatchers teach us anything, it’s that everyone must be allowed to make mistakes.

The concept of “slow birding” recently evolved as an even more radical counter to the competitive and obsessive aspects of birding. Slow birding is about bird/life balance, where birding can be an act of mindfulness. The key point is this: There is no one right way to enjoy birds.

Institutional structures

Across academia and many workplaces, we have seen increased diversity over the past four decades. The US Congress has gone from 3% women in 1980 to 28% today. The same probably could not be said for bird record committees, birding tour guides or birding conference speakers.

One way the birding community creates obstacles to diversity is thru various institutional structures and processes. Sometimes it’s just the name. Outside the affinity-based birding clubs described above, most local clubs are “Audubon societies.” In addition to stereotypes of older white people peering thru trees at warblers, both the words “Audubon” and “society” are turnoffs to youth and people of color. It’s a shame because many local groups do great outreach and local conservation. They can be key points of entry for new birders.

I know many who used to work for National Audubon who now boycott them on principle. Some organizational clarification: National Audubon and various state affiliates (e.g. Audubon California, etc.) are all part of a single 501c3. That is the entity that has refused to change its name. Local Audubon societies, however, are separate 501c3’s; they can change their name any time they want. Seattle, Golden Gate, and many others have done so. The challenge now – and what has caused so much delay – is how to do so in a coordinated way, now that National is failing to provide a model for change.

Sometimes the barriers to entry are more substantial than the name; sometimes it’s the actual bylaws. The most dramatic example involves the North American Checklist Committee (NACC) of the American Ornithologists Society. They oversee lumps and splits (and, until recently, English bird names as well as scientific names). The members have advanced degrees in ornithology and are expert taxonomists. That’s no surprise. What is astonishing is that the members of this committee serve unlimited terms and new members are chosen by pre-existing members. Thus, turnover is slower than the US Supreme Court. Some of the members have been on the committee for over 30 years. Five of the eight members who were on the NACC in the year 2000 are still on today. (It has 11 members today, plus two Latina members from Mexico and Central America.) Only one of the nine Supreme Court justices today was there in 2000. The aim, of course, is doctrinal stability, but it comes at a cost. Such policies limit opportunities for younger academics to even aspire to the committee, and certainly retard diversity on the committee.

In the birding world, many state record committees, which oversee state records and evaluate observations of rarities (declaring what is “countable” for listers), have only slightly less-restrictive policies, often resulting in a revolving door of white males. For many of these committees, vacancies are filled only through the nomination by and approval of the existing committee members, just like the NACC. Given that these committees have only a dozen members at most, and there are hundreds of expert birders in most regions, it seems hard to believe there are not women and people of color qualified to serve. Some committee members I’ve spoken to say they try to reach out to other demographics to nominate them, but their efforts have not succeeded. 

I’m not questioning the qualifications or bird decisions of these committees. Their service is commendable. Regardless, the appearance is of an entrenched aristocracy that appears to exclude women and people of color.

Even Christmas Bird Counts (CBCs), usually terrific opportunities for outreach, are not immune to institutional barriers to entry. There are some CBCs that are run as private clubs, closed to outsiders and beginners. On others, beginners are shunted off to less exciting routes.

Public gate-keeping

While there are plenty of legitimate questions and alternative perspectives for any issue in birding, recent discussions about birding and diversity issues (e.g. regarding committee membership and the re-naming of certain birds) have often crossed a line, being particularly insensitive to women, younger birders, and birders of color.

Recently, a friend of mine, a younger person of color and a beginning birder, joined a local former-Audubon bird club field trip for the first time. As the group began to gather – all older white men and women – the leader initiated a group gripe session about the proposed bird name changes.

I don’t know exactly what words were said, what arguments were made. Just the big picture – that an initiative, motivated by diversity and inclusion concerns, is being most criticized by white men over 65, the exact demographic that is most included and overrepresented in leadership positions – is not a good look.

(I acknowledge there are many prominent white male birders who are supportive of the bird names proposal: Kenn Kaufmann, David Sibley, Nate Swick.)

Apparently it is too much to hope that birding’s enormous diversity problem would somehow frame the overall conversation. Instead, some of the common arguments are premised as if the only people in the room are white, using entire frames of reference that exclude marginalized people from the conversation. In a public forum, these arguments essentially declare birding as white space.

Three examples that my friend may have heard:

1) When society’s morals change, the present morals should not be applied to people of the past.
~ This is a white issue. By “society,” they mean white society. Blacks have always opposed slavery, Natives have always opposed ethnic cleansing. We can debate how much white society has changed. What has most obviously changed is that now there are other voices at the table. These voices have grown up with different narratives about history and about how their families were impacted.

2) This is “wokeness” and “virtue-signaling.”
~ These are accusations by whites of whites. One doesn’t say a Black person is virtue signaling when they talk about police brutality. And one doesn’t call a Native woke when they talk about tribal sovereignty. No, woke and virtue-signaling are modern variations on “n-lover” and “squ*w men.” The use of these terms presupposes that the new initiatives are coming from white liberals. In fact, there are lots of people of color involved.

3) Competency and quality (for example, as a committee member) should always come before diversity.
~ This is insulting to women and people of color. It echos claims that underqualified people are given positions as charity, as “diversity hires.” Women and people of color have their own narrative – that they work twice as hard to get half as far. That they are, in short, often over-qualified. Diversity strengthens organizations so they don’t make the kinds of mistakes we are witnessing today, and also serve as inspirations to attract new people from across the demographic spectrum.

Another version of this is to point out how accomplished and important the angry white men are – that the bear has been poked too much, and thus the pace of change should slow down. Such arguments are both circular and ironic. The whole point is that there should not even be a bear. And if the bear is so angry about a symbolic measure, what about more concrete measures? We should all be on the same team, building a better world for birds and birders.

My friend didn’t go into detail about what arguments he heard at that bird walk. All he told me was that he won’t be going back.

6. Making birding more inclusive requires structural change and specific actions.

If the online debates don’t offer concrete solutions to make birding more inclusive, all those affinity-based groups I listed above do. Those birders are already acting! Some of the books I highlighted above are filled with ideas. I’m going to do a separate blog post later on creative ideas to increase diversity in birding. In the meantime, here are a few:  

  • Increase diversity in leadership positions. Both Robinson (2005) and Rutter et al (2021) found that a lack of role models is a significant barrier to entry. Robinson compares Black participation in birding to golf, noting that, after the rise of Tiger Woods, the number of Black golfers nearly doubled in four years.
  • Change the bylaws of committees to allow for greater turnover (thru meaningful term limits). Use external nominations and external appointments or voting to fill vacancies.
  • National Audubon, which oversees CBCs, should require all CBCs to welcome beginners, and create and provide tools to make that easier. (There are some awesome examples from Canada. Check out this one, where a youth team was given the prized pelagic route on a cool Zodiac donated for the day by a local orca-watching company.)
  • Local clubs should offer a range of birding opportunities, targeting different demographics (e.g. youth, women, underrepresented ethno-racial groups). In Robinson’s survey, one respondent said that “a change in advertising and possible programs scheduled in the right areas, along with support from Blacks who back this effort, can change everything.”
  • Along with trips to Ecuador, promote 1MR and 5MR birding (birding within a 1 or 5 mile radius of your home), which increases bird/life balance, knowledge of local birding patches and environmental issues, local community, and birdability for those unable to travel long distances. It’s also a great way to find rare vagrants, especially at feeders in winter. In a similar vein, promote county birding and environmental big days and big years (walking and/or biking).
  • Outreach to hunters, who have a lot of commonalities with birders. We can be allies.

Finally, if you comment on this blogpost, don’t just say why something won’t work; focus on solutions. Positive suggestions for edits are also welcome. We’re all on the same team, birds are for everyone, and they need more allies.

After hazing and avian flu: Will the last colony of Caspian Terns in the Salish Sea survive?

The Caspian Tern colony, the one across the bay from the Port Townsend waterfront, was just wiped out by avian flu. Nearly. At the start of the summer, we estimated the colony at about 1,800 adults. So far, the Washington Department of Fish and Wildlife (WDFW) – in five trips to the island, roughly once a week – has picked up over 1,100 dead adults and 500 dead chicks.

This is painful on several levels.

First, this colony, on Rat Island just off the tip of the spit at Fort Flagler Campground, is a relatively new phenomenon. Analysis of satellite images suggest it began last year. Unfortunately, in 2022, in two attempts, about 500 to 1,000 adults produced maybe a dozen fledglings. The first attempt was wiped out by human disturbance. A minus-four tide on the Fourth of July enticed many campers to walk from the spit to the island. I personally watched through my scope as a couple with a dog (on a leash) walked right up to the colony, putting all the birds up in the air, and stood there, naively enjoying the birds and filming them with their phones. Unbeknownst to them, gulls were pouring in underneath the cacophonous mob of terns, no doubt devouring eggs and chicks. This is how human disturbance impacts seabird colonies. A month later, the gulls tried again. This time a coyote managed to swim across from Indian Island and had a feast. Coyotes previously wiped out a colony on the tip of Dungeness Spit.

This year we were prepared to at least address the human disturbance problem. As the Conservation Chair of Admiralty Audubon, I reached out to State Parks and WDFW. They contacted the Friends of Fort Flagler, who created a team of 25 volunteers to serve as docents during extreme low tides to intercept and educate beachgoers about the terns – and the harbor seal haul-out next to it. WDFW put up signs around the island to educate kayakers.

Everyone was trained and more birds than ever came to nest. They seemed to be doing great. Most were on eggs, and we estimated they were just about to hatch. Then, on July 10, Sam Kaviar, a naturalist guide who runs Olympic Kayak Tours, noticed a dead tern. Not a big deal, I told him, unless you start seeing more. Within two hours, he saw a dozen more. He called WDFW. They were nearby in a boat so came over to check it out. They collected 35 dead terns and suspected highly pathogenic avian influenza (HPAI), also known as H5N1. They collected carcasses to run tests, which eventually came back positive.

The second painful thing is that Caspian Terns are a long-lived slow-reproducing species. The loss of chicks is one thing, but the loss of adults is a much bigger deal. Caspian Terns, the largest tern in the world, can live 26 years. Most adults live 10 to 15 years. This means they only need to reproduce themselves once every 15 years or so to sustain their population. It also means that, if you lose an adult, it might take 15 years to replace them.

The third painful thing is that Caspian Terns are already declining, both in the Pacific Northwest, up and down the entire West Coast, and across the whole continent. The Birds of the World species account for Caspian Tern, in the section on conservation concerns, highlights their need for disturbance-free nesting sites, “Human disturbance at colonies facilitates egg predation by gulls when more wary terns are flushed from nests.”

The fourth painful thing is that Caspian Terns were deliberately pushed off from most of their other breeding sites in the Pacific Northwest in the past 15 years. They do not nest scattered across the landscape like robins or even gulls. Like many seabirds, they nest in tight colonies, packed together, one nest every few feet. In the Pacific Northwest, enormous colonies were hazed off Sand Island in the Columbia River delta by government agencies because they were eating too many salmon smolts – which are endangered because of the dams. (Note, photos of prey items at Rat Island have shown the terns eating candlefish, herring, smelt, surf perch, and juvenile salmon – the latter only toward the end of their nesting period.) Many relocated to rooftops in Seattle or to empty lots in Bellingham. In recent years, they have been hazed off there too. That is exactly why the Rat Island colony near Port Townsend grew so suddenly. It is a colony of refugees. We have photographed birds there that were banded at Sand Island, in Bellingham, even from the Tri-Cities area. This spring, as the colony was forming, local experts concluded that this was the only Caspian Tern colony in the Salish Sea.

Now 80% of them are dead.

Like Covid, HPAI has recently become part of our world. The United Nations issued a concise report about it in July 2023. They open with this: “H5N1 high pathogenicity avian influenza (HPAI) is currently causing unparalleled mortality of wild birds and mammals worldwide…” They describe it as unprecedented based on the scale of mortality (often approaching 90%) and geographic spread (nearly worldwide). In Washington, it was first detected last winter in waterfowl (mostly Snow Geese) in the Skagit Flats.

This summer’s outbreak at the tern colony is the first known incidence of HPAI in wild birds in the breeding season in Washington. A smaller outbreak is on-going among Caspian Terns at the Columbia River delta. Fears that it would spread to the harbor seals or dogs at the Fort Flagler campground have not materialized. Some dead gulls, especially chicks, have tested positive, though in general, the gulls have been much less affected. There are several hundred “Olympic Gulls” – Glaucous-winged x Western Gull hybrids that nest at Rat Island near the terns. Bald Eagles and Black Oystercatchers are also present near the colony and potentially vulnerable, though no dead birds of these species have been found. The largest seabird colony in the region is at Protection Island, with over 10,000 Rhinoceros Auklets. That is only nine miles away as the tern flies. While terns forage near Protection Island, and auklets forage near Rat Island, there has been no evidence of transmission to the auklets. In fact, HPAI is unknown in alcids so far. 

Hope remains. On my last visit to the island, on August 11, there were still approximately 350 adults. Some were flying into the colony carrying fish. On the beach, I could see about a dozen chicks of varying ages, adults offering them fish, as well as a few dead adults and others that appeared sick. I am hopeful that over 10% of the adults will survive. That sounds pathetic, but it’s a start. Perhaps they will be immune to avian flu and so will their offspring. We don’t know yet. And, despite the carnage, it looks like this colony may actually produce more fledges than last year. So that’s another start. Chicks leave the colony about 45 days after hatching. That should be soon for some of them. They can’t get away fast enough.

eBird Trends maps reveal dramatic northward range shifts in Eastern species

Over a year ago, on a webinar hosted by the Washington Ornithological Society (WOS), John Fitzpatrick of Cornell Lab of Ornithology teased us with some screenshots of eBird Trends maps. I was mesmerized. Now, they have been released here at the eBird Science tab. These remarkable maps illustrate population trends for each species across their range, showing exactly where they are increasing (blue dots) or decreasing (red dots).

They do more than that, actually. The color of the dot is correlated to the rate of change — the % change between 2007 and 2021. Dark blue means really increasing; dark red really declining. The size of each dot is correlated to the size of the population in that area (or “relative abundance” in eBird lingo). Big dots mean there’s a lot of birds there, regardless of whether they are increasing or decreasing. If you hover over a dot, the actual numbers pop up. White dots mean the data are inconclusive or show no trend. You can read more of the details at the site, and perhaps I’ll discuss methodology on a later post.

Here’s the amazing thing — each dot represents a 27 x 27 km (16.7 x 16.7 mile) grid square, so just a bit larger than a Christmas Bird Count circle, which are 15 miles in diameter. That’s a remarkable level of detail. I joke that there’s more information in these maps than in all the ornithological research in the last ten years. That’s an overstatement, of course, because professional ornithologists study things that eBirders don’t. Nevertheless, these maps take crowdsourced data collection and present it in ways that are instantly useful for understanding species population trends at a granular level. This has profound implications for targeting conservation.

So, on to my first of probably many posts looking at these maps. My first peruse suggests they strongly support what the climate change research has been saying — that resident and short-distance migrants are shifting their ranges north. Let’s start with some common eastern species.

CLICK TO ENLARGE

To examine each map in detail, go to eBird’s Trends page, type in the species name, and then click “Trends” to the right of the species’ name.

Until now, most of the published literature on northward range shifts have been meta-analyses with conclusions such as “non-migratory species are shifting north by so many km per year”, but no maps, nor even mention of species by name. Here, we get the details in bright colors, at the species and even county level. Wow.

A few observations. For many species, they are declining where they are still common (the red dots are large), and increasing where they are less common or even rare (the blue dots are small). This probably implies that their overall population is declining. It also suggests that climate change may be hurting them in the south faster than it is helping them in the north. It takes time to establish new populations, and/or the new regions may not be as suitable as their old home. Note also that each of these species have different transition isoclines (if that’s what one would call it). For example, Red-bellied Woodpecker and Carolina Wren are increasing in Tennessee, but Tufted Titmouse are declining there.

Here are some relevant papers regarding range shifts in eastern species, but again, these maps communicate their results in new and vibrant ways:

Prince, K. and B. Zuckerberg. 2016. Climate change in our backyards: the reshuffling of North America’s winter bird communities. Global Change Biology 21(2): 572-585. We conclude that a shifting winter climate has provided an opportunity for smaller, southerly distributed species to colonize new regions and promote the formation of unique winter bird assemblages throughout eastern North America.

Rushing, C.S. et al. 2020. Migratory behavior and winter geography drive differential range shifts of eastern birds in response to recent climate change. Proceedings of the National Academy of Sciences117(23), pp.12897-12903. Since the early 1970s, species that remain in North America throughout the year, including both resident and migratory species, appear to have responded to climate change through both colonization of suitable area at the northern leading edge of their breeding distributions and adaption in place at the southern trailing edges.

Saunders et al. 2022. Unraveling a century of global change impacts on winter bird distributions in the eastern United States. Global Change Biology We conclude that climate has generally governed the winter occurrence of avifauna in space and time, while [habitat] change has played a pivotal role in driving distributional dynamics of species with limited and declining habitat availability.

The maps also support some of my previous blog posts: such as the northward expansion of Northern Cardinal, Carolina Wren, Tufted Titmouse, and Red-bellied Woodpecker, the crash of Florida’s white-eyed Eastern Towhees, certain range expansions of the Lesser Goldfinch and California Scrub-Jay, the expansion of many species from California into the Pacific Northwest, and the failure of oak-dependent species (e.g. Oak Titmouse and Nuttall’s Woodpecker) to go anywhere.

In future posts, I’ll look at range shifts in resident birds of the West, the impact of California’s fires (many encompassing several of these Trends dots), long-distance migrants, nationwide species, waterbirds, and seabirds, among other things.

Eastern Towhee: Can the white-eyed subspecies survive even 1.5C climate change?

eBird abundance map for Eastern Towhee. It is resident in the southeast, but expands north in summer.

The Eastern Towhee, a bird of scrub and thickets, is a common resident in the southeast United States. One subspecies migrates north in summer.

They are a prime example of a species that is considered “Least Concern” by the International Union for Conservation of Nature (IUCN), but “High Risk” in National Audubon’s assessment of birds under climate change. In their 3.0 C scenario, they predict it would lose 83% of its current breeding range, while gaining only 23%.

This is National Audubon’s projection for the Eastern Towhee’s breeding range under just a 1.5C scenario. This would spell extinction for the white-eyed birds of Florida and the deep South.
Their winter range is not anticipated to change much.

These projections are consistent with recent literature showing poleward shifts of species ranges– of the northern edge of their range, of the southern edge, and of their range’s geographic center. The predictions for Eastern Towhee are among the most dramatic.

Recent research also suggests that non-migratory and short-distance migrants are more adaptable to climate change than are long-distance migrants, and more able to shift their ranges. Indeed, we are already seeing that with Eastern Towhee. The Audubon projections appear to be in progress.

Based on Breeding Bird Survey (BBS) data, the Eastern Towhee breeding population in Florida has declined over 50% since the late 1990s. The timing of this is consistent with worldwide ecological shifts which began in the mid-1980s.

The white-eyed subspecies appears to be already in trouble. eBirders in Florida in May and June are encountering the species half as often as they were just six years earlier.

eBird data from Florida, focusing on frequency of lists reporting the species during the May-June period, shows that the maximum frequency has fallen from 18.3% in 2015 to 8.6% in 2021.

Not all range shifts are due to climate. As a scrub specialist, the Eastern Towhee prefers habitat that is in the act of regrowth, such as after a fire or being cleared. But they don’t want a forest either. To quote the Birds of the World species account for Eastern Towhee: “As farmland is abandoned, successional changes produce suitable midseral habitats that towhees favor, and their numbers increase. But, successional time is against towhees, and their numbers decrease as seres age.” That may be the explanation for the Georgia data (orange dots), which show a decline in the late 60s and early 70s, possibly due to forest growth or land clearance for development, and then a leveling off.  

As the climate warms, many species are expanding north and/or declining in the southern part of their range. But these need not happen simultaneously. Opportunities for suitable habitat may open doors in the north, and doors may close in the south, at different times. There is evidence of Eastern Towhee expansion in Minnesota, but look at the vertical axis; it does not compare with the losses in Florida.

In Florida, the white-eyed subspecies faces extinction based on National Audubon’s 1.5C scenario. They appear to have declined dramatically in the past two decades.

Mountain Bird Network seeks eBirders heading into the hills

The east side of the Olympics is a staircase of thrushes. The low country is for American Robins. As you get into woodsy habitat, you’ll hear the spiral song of Swainson’s Thrushes. After that, among the tall old growth along the streams, the ethereal Varied Thrush. Finally, up near timberline, you’ll hear singing Hermit Thrushes. Freeman and colleagues are tracking how these ranges are shifting with the climate.

Two 5-minute point counts at each stop as you gain elevation. June 1 to July 15. Entered into eBird. Shared with the Mountain Bird Network.

That’s all Ben Freeman, a post-doc at University of British Columbia, is asking for. And it can be any mountain, any canyon, any road.

The maddening truth: Feeding crows and jays harms other birds

Backyard bird feeders bring nature close to people, increase appreciation for the natural world, and, in winter, help birds survive. But research also documents some adverse effects, such as the potential to spread avian diseases and to inflate the population of nest predators. There’s a lot of attention on the former, but the latter issue probably does a lot more harm.  

Close to half of all bird nests fail due to predation. Corvids (ravens, crows, jays, and magpies) play a big part in that; they are among the most voracious nest predators, taking other birds’ eggs and chicks. Squirrels and rats are also major nest predators. Open cup nesters are especially vulnerable.

jays and crows eating peanuts
Crows and jays are especially fond of peanuts. Feeding them may depress other bird populations.

Corvids are part of the natural ecosystem, but the problem goes beyond “natural” because many corvid populations are artificially higher due to anthropogenic food subsidies – human garbage, bird feeders, scraps, etc. In short, corvids are often what biologists call human-subsidized predators. Millions of restoration dollars have been spent trying to protect declining species from corvids (e.g., Marbled Murrelet, Least Tern, Snowy Plover, Piping Plover, and Desert Tortoise). Additionally, local populations of otherwise common species are known to be at risk from corvids (e.g. Common Murre, Red-capped Plover). And research shows they can depress bird populations in residential neighborhoods.

The Research

Crumb Clean sign
Sign from Big Basin State Park. Corvid-control measures may include removal (killing or transferring elsewhere), camper education, improved food storage, and food waste management and garbage control, among other measures. There is a vast literature on the topic.

By providing food, humans have a remarkable ability to inflate corvid populations. Brunk et al (2021) examined efforts to reduce Steller’s Jay densities at campgrounds in Big Basin State Park in California in order to protect endangered Marbled Murrelets. Jay densities within the campgrounds were nine times higher than in the surrounding forest. Previous research documented that the Steller’s Jay juvenile survival rate in the campgrounds was over 90%, possibly the highest figure ever recorded for a bird; 50% is more typical. After the installation of new garbage cans, food lockers, as well as extensive camper education, the jays disbursed and densities fell to natural levels. I’m proud to have been a part of that project.

There is a long list of papers that show the depressing impact that high numbers of jays and crows can have on the productivity and populations of other birds. Here are a few examples focusing on songbirds:

Jokimäki et al (2020) looked at nest predation rates in nine European cities, finding that cats and corvids had a significant impact on other birds’ nest success in urban and suburban areas.

Hanmer et al (2017) experimented with artificial thrush nests with quail eggs placed in a natural context but in the vicinity of bird feeders that were offering peanuts. Nests near active feeders were far more likely to be depredated than nests that were far away from peanut feeders. The predators were jays, magpies and squirrels.

Malpass et al (2017) conducted an experiment in seven neighborhoods in Ohio, adding bird feeders during the breeding season to some areas. The neighborhoods with the most feeders had triple the numbers of American Crows and Brown-headed Cowbirds compared to the neighborhoods with the least feeders.  American Robin nest success fell to just 1% in the high-feeder neighborhoods, compared to 34% in the areas with the fewest feeders. Northern Cardinals, perhaps because their nests are generally more hidden, managed to avoid these impacts.

In the Santa Cruz Mountains of California, eggs painted to look like Marbled Murrelet eggs are injected with a chemical that causes jays to vomit. This has trained some jays to avoid them.

Jokimäki and Huhta (2000) looked at bird assemblages across urban, suburban, and natural areas in Finland. They found a dramatically higher nest predation rate in the managed urban parks (53 to 92%) compared to more wild suburban parks (22 to 67%). Additionally, most ground nesting species simply avoided the urban areas. Crows and jays were listed among the primary nest predators.

Stoate and Szczur (1994) reported that corvid removal led to dramatic improvement in the hatching success of thrushes and Chaffinch. Some ground-nesting and thicket-nesting species (Dunnock, Yellowhammer, etc) were unaffected by corvids.

Slagsvold (1980) found that Fieldfare populations (the Scandinavian counterpart to the American Robin) doubled after the removal of Carrion Crows (the counterpart to the American Crow). Smaller songbirds also sought protection and nested near Fieldfares. Many songbirds based nest site decisions on the presence or absence of crows.

There are several meta-analyses, studies of studies, that try to summarize the big picture. Most of these include a wide array of avian and mammalian predators—and most focus on ground-nesting shorebirds and gamebirds, where conservation and hunting interests fuel research funding.

graph of nest survival
Hanmer et al (2017) examined the fate of artificial nests placed 5 and 10 meters away from feeders with peanuts, feeders with peanuts and a protective cage guard to exclude predators, and empty feeders. Approximately 90% of nests near empty feeders survived the first day, and 50% remained a week later. Near active peanut feeders, these numbers fell to 50% and just 10%. Guarded feeders only slightly reduced the impact.

Cote and Sutherland (1997) is typical. It reviews 29 studies, focusing on avian (crows, gulls, grackles) and mammalian (foxes, skunk, marten) nest predation on gamebirds (pheasants, quail, etc) and some songbirds. Removing predators had a large positive effect on the prey species’ productivity and post-breeding population.

It is important to add that not all studies have found a link between corvids and reduced densities of other birds. This seems to be truer in rural contexts. Furthermore, impacts seem to be species-specific. I can imagine, for example, that chickadees and nuthatches, which nest in small cavities, are relatively protected from jay and crow nest predation.

Finally, there is Madden et al (2015), a meta-analysis focusing exclusively on corvids, which caused some confusion. It focused mostly on impacts to gamebirds and did not include jays. It is curious because its summaries and conclusions do not match the data they present. Based on their data, Madden could have concluded with this:

“The presence of crows had a negative impact on other bird species’ productivity in 66% of cases. In 10% of cases, a decline in abundance was also detected. These results suggest that, in certain contexts and for many species, large crow populations may create population sinks or actual declines in the populations of other birds.”

That would have been consistent with other studies, but the paper didn’t end that way. Instead, it summarized the data in ways to bury important results, failed to include some well-known cases involving endangered species, and concluded with this head-scratching statement:

“Our review shows that although there is no consistent pattern with regard to corvid impacts on other bird species, the most commonly reported effect is that corvids have no negative impact on prey species abundance or productivity. When combining experimental and correlative studies (326 cases), most cases (81%, n=264) showed no negative influence of corvids on either abundance or productivity of birds…”

“Most commonly” meant more than 50%. Because they lumped magpies with crows, and lumped abundance with productivity, they were able to say this (barely). I am astonished this paper passed thru peer review with this sweeping, and deceptive, summary intact. Some backyard birders, in defense of laying out a smorgasbord of peanuts on their back patio, have cited this paper on social media.

There’s a lot more I can say about this paper, but suffice it to say their own numbers (see Table 4) imply that two-thirds of studies involving crows found significant impacts to other species’ productivity.

Conclusion: No peanuts, and use caution in the breeding season

Make no mistake—bird-feeders in winter are associated with increased bird survival. There are lots of papers about that. I feed birds in winter (but no peanuts!). In the spring and summer, however, when my juncos and sparrows have departed, those same feeders disproportionately attract jays, crows, and squirrels, as well as House Sparrows, Eurasian Starlings, and Brown-headed Cowbirds. It’s no wonder that open cup nesters have a tough time. In the summer, I maintain hummingbird feeders and have a little pond and fountain that attracts bathing warblers.

Bird feeding in spring and summer, and especially offering peanuts which disproportionately attract crows and jays, likely depresses the populations of other songbirds in the vicinity. This is probably a big reason why many suburban neighborhoods can be largely devoid of cup nesters (e.g. warblers, vireos, flycatchers) while still having cavity and thicket nesters (e.g. chickadees, nuthatches, wrens, towhees).

juvenile American Robin
A good sentinel species may be the American Robin. If your neighborhood is devoid of breeding robins, and especially fresh juvenile robins, it may be due to excessive numbers of jays or crows.

In 2021, Shutt and Lees reminded us that we (humans and jays and warblers) are all connected:  “Generalised provisioning is enthusiastically promoted by many conservation organisations as a means to foster connection with nature and help wildlife. However, such a vast input of additional resources into the environment must have diverse, ecosystem-wide consequences. Direct effects…  are generally positive in leading to increased survival, productivity and hence population growth. However, we argue that the wider implications for the recipients’ non-provisioned competitors, prey and predators are underappreciated and have the potential to generate pervasive negative impacts for biodiversity.”

Restoring Southeast Farallon Island thru mouse eradication: Yes

Islands are special

In contrast to continents, their ecosystems have much fewer moving parts. It’s not unusual for an island to have only a few plant species and often no land bird or mammal species. All of New Zealand has no native land mammals except for bats. The Channel Islands off southern California have only a native deer mouse and the island fox, and that’s only on some of the islands. Southeast Farallon Island has no native land mammals.

I’ve had the privilege of being on Southeast Farallon twice. It’s a magical place, home to thousands of seabirds and marine mammals.

Yet islands are critical refuges for marine mammals and seabirds. It’s not unusual for over 90% of a single species to come from a single island, or just a few islands. For example, over 99% of the world’s Heermann’s Gulls breed only on Isla Raza, a 1.5 acre postage stamp in the Sea of Cortez. 95% of the world’s Black-vented Shearwaters breed only on San Benito Island off Baja California. 99% of the world’s Scripps’s Murrelets come from four islands off southern California and Baja California. And probably 50% of the world’s Ashy Storm-Petrels nest in burrows on a single hillside on Southeast Farallon Island. There are similar examples from all over the world.

A new 4-minute video by Point Blue, summarizing the project.

Islands are vulnerable

This gets us to the final characteristic about islands; they are vulnerable to perturbations. Add one more moving part, and things can fall apart quickly. 75% of all bird, mammal, amphibian, and reptile extinctions have occurred on islands. More bird species have gone extinct on the Hawaiian Islands than on North America, South America, Europe, Africa, Asia, and Australasia combined.

The introduction of a single non-native species, such as rats or mice or cats or even rabbits, can result in massive changes to an island’s ecology, leading to the extinction of native or breeding species. Rats, arriving as stowaways on ships, are the number one cause of bird extinctions worldwide.

Scripps’s Murrelet nest success on Anacapa Island, before and after rat eradication.

When I worked for the California Department of Fish and Wildlife, I was involved in over 300 restoration projects. The best one, the one with the most obvious and dramatic benefits, was when we eradicated non-native black rats from Anacapa Island. In addition to benefitting Scripps’s Murrelets, other seabirds such as Cassin’s Auklets began nesting on the island. The native lizard and even the sea stars and mussels and vegetation rebounded; the rats had been eating them all out of house and home.

Here’s the 4-minute version about Anacapa restoration ten years after rat eradication.

The mouse problem on Southeast Farallon Island

Today, the non-native house mouse is impacting the Farallon Islands, one of the most important seabird nesting colonies south of Alaska.

Southeast Farallon Island, the main island, is infested with the mouse. In fact, there are higher densities of house mice there (more than one per square foot) than anywhere in the world. They eat seabird eggs and spread the seeds of non-native weeds around the island. More significantly, they attract a few migrating Burrowing Owls each fall. The owls, lost over the ocean, would normally stop on the island and then leave. But with the mice there, the owls stay and feast. When the winter rains come, the mouse population crashes and the owls begin to starve. Right about then, the declining Ashy Storm-Petrels begin returning to the island to nest. The owls catch them and stack them like cordwood. (In the most recent review, they were not listed an “endangered” based on the assumption that this project would be implemented.)

One thing to know about Ashy Storm-Petrels is that they are long-lived and slow-reproducing, like most seabirds. With the owls killing the adults, the storm-petrel population cannot recover.

Eventually, the owls starve to death. Then the mouse population rebounds in the spring and the cycle starts over, while the storm-petrel population spirals down. This happens every year on the Farallones.

Restoring the island thru mouse eradication

The plan is to eradicate the house mouse from Southeast Farallon Island, as we eradicated rats on Anacapa, and as has been done on over 600 islands worldwide.

Locations of all of the recorded eradications of invasive vertebrates from islands for which location data are available (n=664). 

The key is to get every last mouse—thousands of them. The only way to do this is to use rodenticide bait pellets. It will be done in the late fall, when the mouse population is at its low point, and when there are very few birds or mammals on the island. The few gulls present can be hazed with a laser (we’ve tested this). Any pellets that fall in the water will quickly decompose. On Anacapa, there were few secondary impacts; the benefits were far greater than we ever dreamed.

Scripps’s murrelet on Anacapa.

This project has been researched by dedicated biologists who know and love the island. We have explored all alternatives. (Contraceptives are not feasible. Introducing more raptors is NOT the answer.) We have researched possible harms and benefits. We’ve seen the amazing restoration of the ecosystem on Anacapa and on 600 islands worldwide, and we’ve worked with experts from New Zealand.

Bird names matter: Top ornithologists and organizations endorse name changes for all species named after people

At the American Ornithological Society (AOS) Congress on English Bird Names on April 16, 2021, a host of prominent organizations and individuals endorsed “bird names for birds”, a widespread effort to rename eponymous or honorific species names with more descriptive names, focusing on their physical or ecological attributes. For example, Wilson’s Warbler could become Black-capped Warbler, Townsend’s Solitaire might become Northern or Juniper Solitaire, and Kittlitz’s Murrelet would probably be re-named Glacier Murrelet.

MacGillivray’s Warbler was named by John James Audubon after his friend, William MacGillivray, a Scottish ornithologist who never came to America. Audubon also coined its Latin specific, tolmiei, to honor William Fraser Tolmie, a Scottish employee of Hudson’s Bay Company based at Fort Nisqually during the period of Native removal. Scientific, or Latin names, are subject to international rules and are not the focus of this process.

While specific new names have not yet been chosen, representatives of the American Birding Association (ABA), National Audubon Society, as well as David Sibley and Kenn Kaufmann, all heartily endorsed developing a process to make the changes, noting that new names would engage a larger audience, contribute to greater equity and inclusivity among birders and the interested public, and could aid in public communication and conservation efforts.

The effort has grown out of the national reckoning on racial equality in the aftermath of the George Floyd killing. Movements to change names are underway with regard to parks, mountains, streets, other wildlife, and even rock-climbing routes. Current names generally go back to the eighteenth and nineteenth centuries during European expansion across North America and recall an era of conquest, when species and landforms were “discovered” – and some named after the individual who documented them, or after their friends and colleagues.

An FAQ, full list of the panelists, and a video of the Congress can be found at the AOS English Bird Names website. The direct link to the video is here.

Sibley commented that, the more he learns about the names, “the more they cast a shadow over the bird” and “the name doesn’t mean just the bird anymore. They have baggage.” Out of respect for people and the birds, they “should not have to carry a reminder of our own fraught history.” Choosing between stability and respect, Sibley stated “I choose respect.”

Name changes over social justice concerns began last year when McCown’s Longpsur was changed to Thick-billed Longspur, after widespread outcry because McCown was a Confederate general and involved in the ethnic cleansing of Native Americans. A proposal in 2018 for that name change was roundly rejected. 

Name changes for these reasons are not new; most birders can probably recall the switch from Oldsquaw to Long-tailed Duck in 2000. At that time, the American Ornithologists’ Union, the precursor to the AOS, asserted that the name change was not for reasons of “political correctness” but merely to conform with usage elsewhere.

The Bird Names for Birds website includes bios of various people memorialized with bird names. For example, Townsend (of the solitaire, warbler, and storm-pretrel) collected Native skulls for his friend Samuel Morton, author of Crania Americana. The November 2020 issue of Birding magazine focused on name changes, with a strong endorsement by ABA President Jeffrey Gordon and a longer article providing historical background. It is available here for ABA members.

Bird Names for Birds, a group of interested birders, was instrumental in reaching out to the larger organizations to participate in the congress. In their words, “Eponyms (a person after whom a discovery, invention, place, etc., is named or thought to be named) and honorific common bird names (a name given to something in honor of a person) are problematic because they perpetuate colonialism and the racism associated with it. The names that these birds currently have—for example, Bachman’s Sparrow—represent and remember people (mainly white men) who often have objectively horrible pasts and do not uphold the morals and standards the bird community should memorialize.” They describe such names as “verbal statues” that should be removed.

Jordan Rutter of Bird Names for Birds argued that, when reaching out to the public to protect an endangered sparrow, Bachman’s Sparrow has much less appeal than an alternative name rooted in local ecology that the public could identify with. Kaufmann pointed out that Bachmann was a pro-slavery white supremacist and that the species was formerly known as the Pinewoods Sparrow.

In the AOS’s own language, “The Community Congress opens the discussion on the complex issues around eponymous English Bird Names…. The specific aim of the Community Congress is to provide an opportunity for a broad range of stakeholders from the birding and ornithological community to share their viewpoints, including challenges and opportunities from their perspectives, to best inform future next steps to address the issue of naming birds after people.”

The AOS Congress on English Bird Names was superbly moderated by José González, providing a model for the process ahead.

Keepers of various ornithological databases also participated in the Congress, including representatives for eBird, Christmas Bird Counts, Breeding Bird Surveys, and the Bird Banding Laboratory. While noting potential complications with name changes (and changes in four-letter banding codes), they all agreed the hurdles were not insurmountable. Indeed, name changes, as well as taxonomic lumps and splits, occur every year, with name changes being the simplest of the three to address in data management. eBird currently supports bird names in 47 languages, including 14 different versions of English. Where Americans see Black-bellied Plover, Brits see Grey Plover.

Marshall Iliff of eBird pointed out that the effort is also an opportunity to clean up old taxonomic messes, pointing out that Audubon’s Shearwater has been used for eleven different combinations of nine different taxa. In this case, he said, fresh names for specific taxa will provide clarity, not confusion. He embraced a worldwide effort to “dig into the essence of each species” to “find inspired and appropriate names.”

For now, the effort will be limited to primary eponymous English bird names. The effort will not include secondary names (e.g., American Crow, named after the continent, which was named after Amerigo Vespucci). Other problematic names, such as Flesh-footed Shearwater for a bird with pink feet, were not discussed.

Many suggested using Native names for species, though most stated this could be challenging because 1) names from Native languages may have been lost, or 2) most bird species’ ranges span multiple historic aboriginal territories and languages, creating a conundrum over which indigenous word to use. The exception to this is Hawaii, where indigenous names are already in widespread use. Among mammals, moose, raccoon, and skunk are all derived from Algonquian.

Does Lawrence’s Goldfinch deserve a better name?

Looking at Version 8.0.8 (March 12, 2021) of the ABA Checklist, 115 of the 1,123 species, or a little over 10%, are named after people. Of these, 2 (Bishop’s Oo and Bachman’s Warbler) are considered extinct, and 20 others are Code 4 or 5, meaning they occur extremely rarely in the ABA area (though three of these are regular in Mexico, within the AOS area). The remaining 93 are all Code 1, 2, or 3, and can be expected to be seen in the ABA area regularly.

Here are the 113 non-extinct species from the ABA Checklist.

There are also several hybrids (e.g. Brewster’s and Lawrence’s Warblers), prominent subspecies (e.g. Thayer’s Gull and Audubon’s Warbler), and superspecies (e.g. Traill’s Flycatcher) that are used in some databases. It is not clear if these will be addressed at this time.

Mojave Desert bird populations plummet due to climate change

Two recent papers concluded that many breeding bird species in southern California and Nevada deserts have declined dramatically due to climate change.

In their abstract, Iknayan and Beissinger (2018) summarized, “We evaluated how desert birds have responded to climate and habitat change by resurveying historic sites throughout the Mojave Desert that were originally surveyed for avian diversity during the early 20th century by Joseph Grinnell and colleagues. We found strong evidence of an avian community in collapse.”

They re-surveyed 61 sites originally surveyed by Grinnell teams in the early 20th century (primarily between 1917 and 1947).

Of 135 species assessed (which included some wintering and migrating species, as well as breeding species), 39 had significantly declined; only one (Common Raven) had increased. This was in stark contrast to similar assessments they conducted of Sierra and Central Valley sites, where more species had increased than decreased and there were no overall declines (not to say there weren’t winners, losers, and range shifts within those regions).

Figure 1B from Iknayan and Beissinger (2018). Every study site had fewer species than previously– on average each site had lost 43% of their species.

Detailed analyses suggested less rainfall and less access to water was the primary driver. Habitat change only affected 15% of the study sites and was of secondary importance. They found no evidence of expansion of species from the hotter, drier Sonoran Desert (e.g. Phainopepla, Verdin, Black-throated Sparrow) into the Mojave Desert.

Consistent with a community collapse, declines were greatest among species at the top of food chain — carnivores such as Prairie Falcon, American Kestrel, and Turkey Vulture. Insectivores were the next most impacted, and herbivores the least. But the declines affected both common and rare species, both generalists and specialists.

Figure 1B from Iknayan and Beissinger (2018), which I’ve augmented with species labels from the database available in the supplementary materials. Other significant losers (red dots), in order of degree of decline, included Western Kingbird, Western Meadowlark, Black-chinned Sparrow, Lawrence’s Goldfinch, Bushtit, Ladder-backed Woodpecker, and Canyon Wren. The yellow dots are newly invasive species: Chukar, Eurasian Collared-Dove, Eurasian Starling, and Great-tailed Grackle.

A follow-up study by Riddell et al (2020), also involving Iknayan and Beissinger, focused on the thermoregulatory costs — the water requirements to keep cool — for the declining species. They found that “species’ declines were positively associated with climate-driven increases in water requirements for evaporative cooling and exacerbated by large body size, especially for species with animal-based diets.” Larger species get much of their water from the insects they eat. They estimated larger species would have to double or triple their insect intake to meet their water needs, though insect abundance is lowest July thru September.

American Kestrels were among the biggest losers in the study, struggling to meet their cooling needs.

Intriguingly, they found that 22 species had actually declined in body size over the last century, consistent with Bergmann’s Rule, and had reduced their cooling costs up to 14%. These species fared better. Current climate change, however, is at least ten times more rapid than any previous warming event, during which many species evolved. They estimated cooling costs have already increased 19% and will reach 50% to 78% under most scenarios, far outstripping any species’ ability to evolve through the current rapid warming.

These results stand in stark contrast to the Pacific Northwest, where many of the same bird species (e.g. Anna’s Hummingbird, Turkey Vulture, Northern Mockingbird) are increasing. This is consistent with projections which generally show individual declines along species’ southern edge and expansions at the north edge of their range (see Audubon climate projection maps for individual species).

Iknayan and Beissinger conclude, “Our results provide evidence that bird communities in the Mojave Desert have collapsed to a new, lower baseline. Declines could accelerate with future climate change, as this region is predicted to become drier and hotter by the end of the century.”

Keep Davis Water Treatment Ponds wild

The ponds at the Davis Wastewater Treatment Plant have been one of the top birding spots in Yolo County for over 50 years. With 212 species reported via eBird, only two other sites in the county have recorded more (Yolo Bypass Wildlife Area and Davis Wetlands).

Here’s a short video clip from October 2020 illustrating the amazing bird life. A family of Sandhill Cranes walks among thousands of geese, ducks, and shorebirds while the calls of curlews filled the air. A Peregrine Falcon and a Northern Harrier buzzed past. Though the ponds are no longer part of the water treatment plant operations, they still collect rain water and provide habitat. Over 14,000 ducks have been counted on them during the annual Christmas Bird Count. The list of rarities includes everything from Slaty-backed Gull and Arctic Tern to Vermillion Flycatcher.

Earlier this year, the Davis City Council voted 4-1 to lease these ponds to BrightNight solar to convert these ponds into a solar array. Aside from the obvious risk of bird mortality from panel strikes, the project would eliminate one of the best bird habitats in the county. The City Council’s decision has been criticized for its impact on wildlife, for the improper process bypassing the Natural Resources Commission, and for its poor financial terms (the city got ripped off). Gloria Partida, Dan Carson, Will Arnold, and Brett Lee approved it. Only Lucas Frerichs voted against the deal.

But it’s not too late to try to stop it. Here’s what you can do:

1. Call or email each City Council member and ask them to rescind their original vote. Their phone numbers are available here. We need three of them to overturn the original decision. Will Arnold has expressed regret for his vote and Gloria Partida was skeptical at the outset. We also may have an opportunity after the election with new Council member to overturn this decision.

  • Gloria Partida — gpartida@cityofdavis.org
  • Will Arnold — warnold@cityofdavis.org
  • Dan Carson — dcarson@cityofdavis.org
  • Brett Lee — blee@cityofdavis.org
  • Lucas Frerichs — lucasf@cityofdavis.org

2. Call or email Valley Clean Energy Alliance board members and ask them to reject the bid from BrightNight for a new power contract. Their emails are here:

  • Angel Barajas — angel.barajas@cityofwoodland.org
  • Dan Carson — dcarson@cityofdavis.org
  • Lucas Frerichs — lucasf@cityofdavis.org
  • Gary Sandy, Vice Chair — gary.sandy@yolocounty.org
  • Don Saylor — don.saylor@yolocounty.org
  • Tom Stallard, Chair — tom.stallard@cityofwoodland.org
  • Duane Chamberlain, alternate — duane.chamberlain@yolocounty.org
  • Xochitl Rodriguez, alternate — xochitl.rodriguez@cityofwoodland.org

3. Join the effort to increase transparency in City government that would have prevented this travesty. You can see more on that here.
