How the lockdown has helped birds — or has it?

by Anders Gyllenhaal July 7, 2020

A surprising thing happened at the Wild Bird Unlimited store in Raleigh, N.C., when the pandemic struck and shut down almost all of the retail stores that surrounded them.

Suddenly, their business started booming.

All kinds of new customers, stuck in their homes at the height of the spring migration, began tuning in to the nearby birds, often for the first time. Demand jumped for feeders, bird seed and the birding supplies that Wild Birds specializes in.

“We worked out a way to have curb-side service,’’ said Arlette Early, who helps operate the shop. “It was so busy.’’

The widespread embrace of birding is one part of an unexpected phenomenon unfolding in the midst of the pandemic. At a time when many species have been in decline for years, the slowed economy, reduction in human activity and the growing interest in birdwatching could end up helping birds in ways nothing else has.

The relief could be momentary, and some worry that the push to restart the economy now underway could run over wildlife protections and end up making conditions worse than before the virus.

Rebuilding troubled species takes decades of patience and persistence

What does it take to rebuild a depleted species with birds bred in captivity? In the case of one of the longest-running breeding projects, it can take decades of patience and persistence – and hundreds of chicks added to the wild for every one that will go on to thrive.

Our stories in the Washington Post on the rescue mission of the Florida Grasshopper Sparrow prompted a call from the research project that has been working for more than 20 years to save the Loggerhead Shrike in eastern Canada. Researchers there have valuable perspective on the laborious process of captive breeding.

“In our case, it’s years in the making,’’ said Jane Hudecki, coordinator for the Shrike conservation breeding program with Wildlife Preservation Canada. “It can be a tough field to work in.’’

Added Hazel Wheeler, the lead biologist on the project: “I’ve certainly read a lot of papers that speak to the long-term investment needed for a successful recovery program.”

There are a number of parallels between the shrike project and the mission to save the Florida Grasshopper Sparrow, which just had its first hatchings produced by captive birds in the wild. While both programs have figured out how to raise, release and establish mating pairs, questions loom around what it will take to restore the wild populations to strength.

Wildlife Preservation Canada has released 1,300 Loggerhead Shrikes since the recovery program’s formation in 1998. Still, only about 20 breeding pairs remain in the areas of Ontario where the local subspecies settle for the spring and summer. “Basically, we’re just keeping the wild population stable,’’ she said.

The Canadian shrikes and Florida grasshopper sparrows are very different species, living on either end of the continent.

New Flying Lessons column: What are Florida Birds Telling us?

by Anders and Beverly Gyllenhaal May 13, 2020

written by Anders and Beverly Gyllenhaal

Florida is a head-spinning place to go birding. One day you’re chasing a flock of Roseate Spoonbills across 140,000 acres of pristine wetlands, and the next you’re watching Purple Gallinules forage in a ditch a short jaunt from a Starbucks.

A few weeks ago, we tracked Endangered Red-cockaded Woodpeckers through a state park without meeting another soul. On nearby Interstate 95, two Sandhill Cranes grazed on the grassy shoulder as traffic whizzed by a few feet away.

The Florida peninsula has a rich avian landscape, home to more than 500 species, found from the mangroves in the Keys to the Panhandle’s oak hammocks. An impressive 10 million acres of parks, refuges, and other protected areas are managed for conservation.

But Florida is on a collision course with its birds. People and birds tend to like to live in the same places here, and with 21 million residents, Florida now ranks as the third-most-populated state.

It’s fascinating, so Florida became the first stop on our five-month road trip around the country — a birding safari of sorts. In January, we packed up our Airstream trailer, gathered binoculars and cameras, and headed south from our home in North Carolina.

This is a new column running in the latest issue of American Bird Conservancy magazine and is reprinted here with permission from the Bird Conservation quarterly. The column, under the name Flying Lessons, is meant to build on our travels to explore what we’re learning from birds. While we’ve had to put off our birding trips for the time being, we hope to be back on the road before long. We’ll post these columns as they appear. You can get a subscription to the magazine if you donate $40 or more to the conservancy. Here’s the donation link. Finally, if you’d like to see the column as it’s running in the spring edition of the magazine, you can find it here.

The transformation in bird research may hold the key

by Anders Gyllenhaal May 5, 2020

written by Anders Gyllenhaal

One of the topics we explore here on Flying Lessons is the transformation taking place with modern bird research. When we start talking about this with friends and relatives, it can be hard to hold their attention.

But here’s why this is worth sticking with: At a time when habitat loss, climate change and urban hazards have destroyed a third of the bird population in our time, the best remedy may be the powerful technologies that scientists are using to create more powerful conservation practices.

One such story is running this week in The Miami Herald, about a radio telemetry system at the Archbold Biological Station in Central Florida where we visited a few months ago. The research project equips young Florida Scrub-jays with solar-powered tags that enable scientists to track their every waking move.

Scrub-jays, the only bird found exclusively in Florida, have steadily lost population to development as the state has grown into the country’s fourth most populated. Researchers think they can halt the jays’ decline if they understand how to make the most of the remaining scrub habitat, including a string of public lands through the state’s mid-section.

These studies are expensive and time-consuming, and they require a level of public and political support that doesn’t come easily. That’s why we think it’s worth coming back to these research projects and trying to tell the stories in detail. We hope you’ll take a moment to read this piece in the Herald, as well as earlier Flying Lessons posts on the Scrub-Jay, one about the striking character of this bird and another about the early findings on this study.

What the Grasshopper Sparrow is teaching us as it skirts extinction

by Anders Gyllenhaal May 2, 2020

written by Anders Gyllenhaal

For the next month or so, biologists from a coalition of wildlife agencies will be standing on the sidelines of a grassy prairie in Central Florida, pacing like worried relatives in a hospital waiting room.

A captive-bred sparrow steps from its cage.

They’ll be peering through binoculars and listening for bird calls for signs of the revival of the Florida Grasshopper Sparrow, whose total population has fallen to a just 30 breeding pairs.

Our article on the campaign to save the sparrow runs this week in the Washington Post. It’s a story about the mysterious decline of one of Florida endemic species and how a consortium of state, federal and non-profit agencies is staging a biological intervention sparrows bred in research centers to hold off extinction.

Sarah Biesemier (left) and Juan Oteyza, state biologists who oversee the project, arrive at the prairie with a carrying case full of sparrows.

It’s also a story about what’s happening on the front lines of the world of birds in a time of extraordinary change. On the one hand, researchers have built more tools, they’ve developed better research practices and they know more about birds like this sparrow than ever before. On the other hand, the threats to many species are unprecedented. A study in the journal Science a few months ago found that a third of North America’s breeding bird population has vanished in the last 50 years.

We came home from weeks in Central Florida, after visiting the research centers and talking to dozens of scientists, with a question nobody could answer very well: Do we have the collective wherewithal, and the financial and political capital, to put this kind of rescue mission together for the growing number of species certain to need it in the future?

Every grasshopper sparrow on the prairie is identified and tracked by four bands on its legs to follow their progress.

The Florida Grasshopper Sparrow is not the most likely candidate to win the kind of scientific full-court press it’s getting. It’s a small, brown, nondescript bird that’s never seen by most people. It’s found only on the Florida prairie, a unique environment slowly evaporating as the state grows. As a brand, this sparrow is on the far end of the appeal spectrum from such conservation successes as the Bald Eagle, the California Condor and the Osprey.

And yet, an ambitious plan has come together on behalf of this bird. It’s powered by state and federal researchers, some of whom have devoted their careers to studying Florida’s birds, and it’s supported by such non-profits as Florida Audubon and the Fish and Wildlife Foundation of Florida (which just announced a grant for this project.) It is all the more impressive given the anti-environmental streak now running through modern politics.

The consortium makes a persuasive case that the grasshopper sparrow should be saved: It is one of the symbols of the Florida environment. With its haunting song and its place on nature’s ground floor, it’s a key piece of the puzzle of the biosphere we rely on. “The grasshopper sparrow is one of Florida’s flagship birds,” said John Fitzpatrick, director of the Cornell Lab of Ornithology.

Flying Lesson: The Florida Grasshopper Sparrow is a harbinger of a future in which many species are threatened with extinction. Researchers have built an ambitious rescue plan to save this bird, but is there enough public and political support to undertake missions like this for dozens of birds at the same time?

An unexpected discovery: These birds are a lot more like us than we knew

by Anders Gyllenhaal March 17, 2020

written by Anders Gyllenhaal

When researchers built a giant grid of radio receivers for tracking birds in the sandy fields south of Orlando, they hoped to find new ways of protecting the struggling Florida Scrub-Jay.

They discovered something else along the way. Birds are a lot more like people than either species might have thought.

The grid concept is something new in bird research. By setting up receivers throughout the Scrub-Jay’s territory, and then equipping the birds with solar-powered tracking devices, biologists can follow the birds’ every move all day long for months at a time.

The research is still in its early stages, but some intriguing behaviors have jumped out:

Like teenagers everywhere, the young jays form tight cliques of favorite friends. Like many parents, adult jays try to build enough territory to pass sections along to their offspring. When the birds start looking for mates, they come up with ways of sizing up the competition – and sometimes coming between couples.

Archbold biologist Reed Bowman looks over a map of the Scrub-Jays’ territory

“It turns out that they have very complicated social lives that aren’t that different from ourselves,’’ said Reed Bowman, a research biologist at the Archbold Biological Center that has been studying the Florida jays for decades.

The Florida Scrub-Jay is one of the state’s most popular birds and an uncommon segment of the jay species. They’re found only in Florida – and now only in a few central Florida counties. They’re unusually friendly toward humans. Proponents have pushed, so far without success, to make the Scrub-Jay the state bird in place of the more ordinary Mockingbird.

But they’ve been in a long, steady decline, mostly because the jays are so dependent on dry, elevated and mostly treeless habitat that has steadily been lost to development. Wildlife managers are trying to learn how to protect the last 4,000 Florida Scrub-Jays.

The Archbold researchers believe the key is understanding how the birds use what’s left of their habitat. They want to know how the young birds approach breeding and what wildlife managers can do to create the best environment.

At first, researchers thought they could conduct this research by simply watching the jays in the field. “But you could only track a handful of birds at a time,’’ said Young Ha Suh, a doctoral candidate at the Cornell Lab of Ornithology and the project’s lead researcher. “It was really time-consuming.’’

Birding research Conservation Migration Species

Here’s a springtime gift: Powerful new birding tools arrive just in time for the migration

by Anders and Beverly Gyllenhaal March 11, 2020

written by Anders and Beverly Gyllenhaal

For years, the twice-a-year migration of billions of birds was one of nature’s most spectacular events that we never really got to see. That’s because most of the action takes place out of sight, far above us and often at night.

That began to change in the last decade with new technologies for tracking birds, and last week brought a milestone: The Cornell Lab of Ornithology completed a massive project that creates maps and animations for nearly all North American species.

The result is an unprecedented view of how birds move, arriving just in time for the spring migration.

This is big news for anyone interested in birds. The data in this project, all of which is free, will strengthen everything from scientific research and conservation to the power and precision of the tools you use on the birding trail.

The impacts are so far-reaching that Beverly and I couldn’t agree on what’s most important here. So we thought we’d each make our case and let you come to your own conclusions.

Beverly: The best way to appreciate this work is to start by looking at one of these animations. They’re beautiful, with patches of bright colors flowing back and forth across a map of the hemisphere that represent migrating birds week by week throughout the year. I think these are the most compelling — and entertaining — of all the maps and illustrations that come under Cornell’s eBird umbrella. You can find a complete list of the maps by species here on the Cornell website.

For example, here’s an animation of how the tiny Canada Warbler travels the length of the hemisphere twice a year.

Not only can you watch the warblers’ weekly progress from far north Canada to Latin America and back, but you can use these maps to help figure out when they’re like to pass by you. And when you’re trying to find a bird you’ve never seen before, knowing exactly when the largest flocks are arriving is a huge help.

Anders: The point is that animations like the Canada Warbler, along with abundance, range and breeding maps, now exist for 610 species, which make up almost all of the species in North America, in archives Cornell calls status and trends maps.

The lab began putting these together about two years ago as a way to convert their raw bird data into compelling maps and show how birds move through the seasons of the year. The first batch of maps covered about 20 percent of the species, but the addition of the rest of the species opens all sorts of possibilities for comprehensive research and conservation approaches.

“This is a big jump in terms of the utility of the data project,’’ said Daniel Fink, a senior research associate at the Cornell Lab.

Here’s some good news: How a finicky, focused bird made its way back

by Beverly Mills Gyllenhaal February 27, 2020

written by Beverly Mills Gyllenhaal

A couple of days ago someone asked me what bird I’ve found most interesting to write about so far. The answer caught me by surprise – it was the Red-cockaded Woodpecker, the only endangered woodpecker in the country and the bird I happened to be researching at that very moment.

When you hear how finicky this bird is, you’ll understand why he’s so fascinating – and why he was headed toward extinction 50 years ago.

For starters, the Red-cockaded Woodpecker can only survive by boring a hole 20 feet high in either a loblolly pine or a longleaf pine. (Yes, just two trees.) The tree needs to be at least 70 years old. Furthermore, the pine has to be alive, but its heart must be diseased and starting to rot.

To make matters worse, each bird requires its own hole in its own tree. While the Red-cockaded does live in cooperative family groups, they refuse to cohabitate.

They don’t tolerate neighbors either, so it takes from 3 to 60 acres of old southern pine forest to support one family’s lifestyle. Let another Red-cockaded try to cross its boundaries, and the resident woodpeckers will chase it off.

From time to time, in order to stay healthy, nature demands that these forests catch on fire to clear the understory of hardwood trees that impede the woodpecker’s flight and to destroy smaller vegetation that harbors its predators. (The fire doesn’t harm the birds. They fly out of the way and return when the flames peter out.)

A recap: Each Red-cockaded Woodpecker family needs at least three acres of charred forest in the Southeast with one of two types of pine trees that are 70+ years old and dying but not dead.

Without it, the entire species goes caput.

Floridians and their Scrub-Jay: Can they coexist?

by Anders Gyllenhaal January 29, 2020

written by Anders Gyllenhaal

It’s the height of the birding season in Florida, where some 500 species can be found from the sawgrasses marshes of the Everglades to the North Florida oak hammocks. But if you had to choose a single ambassador for the state’s huge bird population, it would be the Florida Scrub-Jay.

Photos by Anders Gyllenhaal

These beautiful blue and gray birds are so full of personality and appeal that there are on-and-off-again pushes to make them the state bird. The Florida Scrub-Jay is the sole bird found only in Florida. And they’re among the most social creatures you’ll ever encounter.

When we finally found them on a small preserve just west of Titusville midway into our January swing through Florida, this family of jays acted as if we were long lost friends:

They flew back and forth in front of us as if showing us the way. They took up perches just a few yards off and launched into nonstop greetings – (or scolds; it was hard to tell which). They hopped around on the ground as if in charge of entertainment for our party of birders.

In many ways, the Florida Scrub-Jay is the symbol for Florida’s bird story. On the one hand, Florida is near the top of the list of states for its number of resident and migratory species. On the other, it’s struggling to keep from losing several of its most prominent indigenous birds, including the Scrub-Jay.

“The big thing that threatened the Florida Scrub-Jay is that they occur in high dry ridges of land,’’ said Reed Bowman, a research biologist with the Archbold Biological Station and one of the state’s experts on Scrub-Jays. “And that’s also where all the people want to be.”

About 4,000 Florida Scrub-Jays remain in a handful of scattered Central Florida patches of elevated scrub land that sit on sandy soil, with low bushy growth and few trees. As development consumes what’s left of this habitat, state and county researchers are waging a campaign to keep the jays from dwindling further, to the point of moving whole families when their territories are threatened.

“We’re losing land by the minute,’’ said Johnny Baker, a Brevard County land manager who watches over some of the remaining Scrub-Jay families. “We’ve got to preserve what’s left.’’

The story of the legislation to make the Florida Scrub-Jay the state bird helps explain why they’re in trouble in the first place. Opponents in Tallahassee have cited a list of reasons for keeping the common, unexciting Northern Mockingbird in that perch. But the unspoken truth is the powerful development lobby is afraid the special status might get in the way of further construction, say those in the know.
