Fledglings take flight: Good news for the nation’s most endangered bird

by Anders Gyllenhaal September 9, 2020

The wildlife managers who bred more than 200 Florida Grasshopper Sparrows in a laboratory setting over the past two years knew they faced a tricky question when it came to releasing the birds into the wild this spring:

Would they know how to act like grasshopper sparrows?

Could they sing the sparrow’s unique courting song? Would they know how to hide from hawks? Would they have the instincts to build nests, mate with wild sparrows and raise their young together?

The captive-breeding experiment is the culmination of a decades-long project to revive the most endangered species in the U.S.. Only 30 pairs of the sparrows remained in the wild when the team decided they had no choice but to try producing chicks in captivity, then introducing them back into the wild in hopes they’d multiply.

The answers to all their questions came pouring in over the course of the breeding season that is now coming to a close.

The birds not only mastered the routines of the mating season, they gave birth to a new generation of Florida Grasshopper Sparrows over the summer. ( Forty-two birds were born from captive-bred birds and altogether 64 were born from wild and captive-bred birds.) Almost all have now left the nest and flown off to begin life on their own.

“We’re very happy with what we saw this first season,’’ said Juan Oteyza, the research biologist with the Florida Fish and Wildlife Institute that oversees the project. “It seems to be paying off.’’

Craig Faulhaber, avian conservation coordinator for the state Fish and Wildlife Conservation Commission, said it was hard to tell the captive-bred from the wild sparrows. “They showed all the normal behaviors,” he said. “They bred successfully. They took care of their young. They acted just like wild sparrows.”

Flying Lesson: The project to save the Florida Grasshopper Sparrow has been full of discoveries for researchers. They’ve learned what it takes to breed birds in captivity, protect fragile nests from harm and how to begin to replenished the depleted population. It’s not yet clear if the project will be successful, but already the lessons are proving valuable to help understand the woes of the grassland birds like the sparrow.

Birding research Migration

Spring migration helped save our sanity; can the fall migration finish the job?

by Beverly and Anders Gyllenhaal September 4, 2020

written by Beverly and Anders Gyllenhaal

Last spring, in the midst of the monotonous stay-at-home months, the spring migration not only saved the sanity of many but it helped launch a wave of new birders who discovered the wonders of the avian world just outside their windows.

As the fall migration gets started, it’s time to get back on the trails and pick up where we left off. If you are new to birding, there are some important things to know.

First off, a lot of birds will look much different than they did a few months before, making identifications tricky. That’s because some species, particularly male warblers, shed their brilliant breeding feathers, and the new ones aren’t nearly so distinct and colorful. Some guidebooks go so far as to call the fall birds drab.

To make matters more complicated, many young birds, eagles and gulls for example, are all splotchy and streaked and look nothing like their black-and-white parents.

Before you head out, it’s helpful to page through a guidebook to compare the fall and spring birds. And if you haven’t yet used the Merlin Bird ID app from the Cornell Lab of Ornithology, this is the time to start. Merlin is a free bird identification wizard that combines science, data and your cell phone’s geolocation. All you have to do is answer three simple questions, and the list of possible birds pops right up on your screen. Click here for more info.

The startling page of the Merlin Bird ID app

The good news is that the fall migration offers a lot of chances to practice your identification skills. This is a slow-motion show that stretches from mid-summer through the beginning of January. If you happen to miss one group, never fear. Billions of birds from hundreds of species are close behind, with ducks and geese generally bringing up the rear. Even within the same species, a few birds can arrive early and a few will be stragglers.

The timing varies depending on where you live.

Ducks like these Blue-winged Teals move south late in the migration.

For new birders busy building a life list of sightings, knowing exactly what to see when and where can be vexing – especially in a time of social distancing. Fall is usually a great time to take birding walks led by experts from local Audubon chapters, nature centers and at fall birding festivals. (While these group outings aren’t available for Fall 2020, another option might be to hire a private guide. Google “birding tour guides” for your location of interest.)

One other helpful tool is called BirdCast, a joint project between the Colorado State University, Cornell and the University of Massachusetts at Amherst, that provides real-time projections on its website and in alerts about the amount of migrating birds around the country. BirdCast even has a tool where you can search your area for real-time alerts as to how prevalent migrating birds are on any given night. Click here.

Developed over 20 years, the concept tracks the daily flow of birds during the migrations, which is useful for protecting birds, conservation efforts and also to help birders know when the chances are best of seeing birds. Much of the migration action is aloft at night, but birdwatchers can improve their chances of spotting birds the following days on the ground.

And here’s a portion of a post we wrote last spring about the expansion of Cornell’s newest and most powerful tool for birders that will help with your fall migration planning. These are beautiful and information-rich maps and animations that track most of the North American species over each month of the year. You can find a complete list of the maps by species here on the Cornell website.

The full development of these maps are so valuable to birders 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.

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 the bulk 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 practical 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.

Go to the end of this post for a summary of the full lineup of birding options from Cornell.

Beverly: Any dedicated birder will be excited about the research and conservation possibilities. But the reason to put a focus on the birders in all of this is that we are helping to create the data.

Every time birders file checklists of species on their eBird app, Cornell collects the data in the first step of the process. Each checklist tells the number of birds spotted and exactly where they were.

As eBird has gained traction, the number of users has risen dramatically — with a total of 500,000 regular users to date who together have filed about 42 million checklists. That’s a lot of birds.

In the past two years alone, the number of visitors to eBird overall has nearly doubled, jumping from 2.6 million in 2017 to 5.2 million in 2019, said Ian Davies, the eBird project coordinator. About half of those visitors submit checklists of the birds they see that, once enhanced by radar and weather data, is the raw material for Cornell’s maps and animations.

“I never fail to be amazed at the collective power of people who appreciate birds,” said Davies. “None of this would be possible without people who care about birds.”

Anders: That’s a really important point, and I would guess one of the reasons contributors are increasing so much is because birders understand how our checklists serve the greater good.

Amanda Rodewald

Amanda Rodewald, director of conservation science at the lab and an ornithology professor at Cornell, said wildlife managers and bird organizations are using the data and maps to guide conservation plans — including more targeted measures than weren’t possible in the past.

One of the best examples is in California’s Central Valley, one of the nation’s agricultural centers that doubles as a flyway for birds. Biologists are working with farmers to flood their fields during a few weeks of migration to provide stopover for migrating birds.

This has dramatically increased the birds coming through, and also enables farming on those fields for all but a few weeks of the year.

“This project gives us so much more information from which we’re able to make really good decisions about the kind of conservation actions that are needed,’’ Rodewald said.

Beverly: The great thing about using these apps for birding is that you get back as much as you’re giving.

Every time you file a checklist, you’re building a lifetime list of every bird you’ve ever seen. Cornell stores the information online in your personal account, and you can refer back to your checklists at any time or download your own data. You can also see the checklists of other birders to figure out which species you’re most likely to see, and where, on any given day. We almost always use eBird to help us choose where to go birding — and even at what time of day. We use the companion app called Merlin Bird ID to help us immediately identify birds we don’t yet know. I still can’t believe it’s all free.

Anders: The last point to make is that this data and mapping provides the research firepower at a time when understanding the science of birds can help protect them.

Scientists once had to work from rough estimates of bird populations, and mere guesses about migration. Now they can draw on precision data on what birds are doing, how many there are and where they’re going.

In the last year alone, we’ve seen some of the most important avian research of our times, including major studies on the loss of about a third of the bird population, shifts in the timing of migration in North America and the likely impacts of climate change on birds. All told, eBird data has been used in about 300 scientific studies around the world.

“The data allows us just an unparalleled lens into the movement, the distribution and the abundance of birds,’’ said Cornell’s Amanda Rodewald.

Cornell data on birds comes in several forms, all free and each with different strengths. The most useful and portable for the birder in the field is found on the eBird smartphone app, which draws from raw data and is the most up to date guidance on where birds can be found. The eBird app is also how you file checklists and keep up with your life list. The companion Merlin Bird ID smartphone app can help you identify birds you see. On the Cornell eBird website, you can find a wealth of maps and species data. For maps and species information, go to the Explore section of the website. You’ll find an introduction to the status and trends maps that are the subject of this post under the Science section of the Cornell website. With so many places you can go for data, it can be confusing to find your way. But if you learn to use all these tools, they provide excellent guidance for finding species, understanding their practices and habitat and tracking their paths through the year.

Beverly: Let’s wind things up with an animation, this one of the Barn Swallow, another long-distance migratory bird that travels from Canada to the southernmost reaches of South America. It’s fall, and all these birds are headed our way. I can’t wait to get out there and start counting!

Beverly's Birding Basics Birding Birding guidance

You’ve started down the path to becoming a birder. What next?

by Beverly Mills Gyllenhaal August 25, 2020

written by Beverly Mills Gyllenhaal

Let’s say you started birding in the pandemic, bought binoculars, and now you’re hooked. You can identify the songbirds and woodpeckers in your neighborhood. So what happens next?

I’ve been thinking a lot about that question while hiking through an Audubon sanctuary in western Massachusetts, peering through bushes looking for fist-sized birds that have no interest in being seen.

Time is of the essence. The American Redstarts, Chestnut-sided Warblers, the Black-and-Whites, the Yellow Warblers and all the other varieties that spend the summer here will start migrating south any day.

Not that long ago, I didn’t know a warbler from a sparrow. So exactly what does it take to become a good birder? Once you’ve moved past the cardinals, blue jays and robins, what’s keeping you from finding the Indigo Bunting or a Rose-breasted Grosbeak?

A female Rose-breasted Grosbeak

Becoming a birder is a process, and it could go any number of ways. Some of it depends on your personality, how much time you have and how mobile you are. Do you like to collect things? Do you crave the thrill of the hunt? What’s your frustration tolerance?

Let’s say you’ve spotted a bird you can’t identify. Would you rather use a book to compare diagnostic markings such as eye rings and the color of a bird’s bill and feet? Or would you prefer a phone app designed to help you identify the bird easily and instantly. Perhaps you’d want a fellow human who can guide your way.

The Ovenbird takes to the stage

by Anders Gyllenhaal August 5, 2020

written by Anders Gyllenhaal

You can usually hear the Ovenbird from a long way off. Its piercing, crystal clear voice cuts through the woods as if singing through a sound system at a Broadway theater.

This is a bird that deserves a stage.

PhotoPost, a new feature on Flying Lessons built around visuals, starts with a video that puts you in a front-row seat for an Ovenbird’s performance:

We aren’t the first to be captivated by the Ovenbird, a stately warbler with oversized eyes and striped plumage that looks like he’s dressed up for the occasion. (Actually it helps the birds blend in with the ground where they spends much of their time.). The species is named for the nest it builds that looks like a tiny bread-baking oven.

The Ovenbird has long been recognized for its song. More than a century ago, poet Robert Frost wrote a sonnet to its haunting tune that, to the poet’s ears, mourned the passing of the season in mid August.

When it sings, the Ovenbird throws its whole body into the act, raising its head to the canopy and turning this way and then that.

Here’s another take on the Ovenbird that puts its song in the orchestra of the dawn chorus. Lang Elliott has spent 30 years recording the sounds of nature, collected on this intriguing website. A few years ago, he captured the Ovenbird leading the birds at dawn in this recording.

The Ovenbird is so loud and consistent that researchers have turned to its songs when needing to study bird audio. The most famous findings dates back to 1958.

Researchers concocted a complicated test that let them compare the Ovenbird’s reaction to birds it had heard before against those it hadn’t. The study came to the important conclusion that Ovenbirds, and presumably other species, can tell the differences in tones of the songs of other birds. That study had stood for decades as a premiere finding on the listening skills of birds.

Most birds don’t give you much of a show before fleeing when people approach. But every time we’ve come across an Ovenbird they’ve delivered a whole symphony of birdsongs. Most of these photos are from an encounter in the North Carolina mountains this summer. We were walking through the Dupont State Forest on the North and South Carolina line when we heard the Ovenbird’s unmistakeable voice that seems to sing “teacher, teacher, teacher.”

At first, we couldn’t locate the bird, but he wasn’t going anywhere so we had time to look for him. We finally zeroed in on a low branch, not far from our path — and there he was as the video above captured, pure poetry.

Robert Front’s poem is about the bird — and also the observer and the passage of time. We’ll let him have the last word:

——————————————–

The Oven Bird

There is a singer everyone has heard,

Loud, a mid-summer and a mid-wood bird,

Who makes the solid tree trunks sound again.

He says that leaves are old and that for flowers

Mid-summer is to spring as one to ten.

He says the early petal-fall is past

When pear and cherry bloom went down in showers

On sunny days a moment overcast;

And comes that other fall we name the fall.

He says the highway dust is over all.

The bird would cease and be as other birds

But that he knows in singing not to sing.

The question that he frames in all but words

Is what to make of a diminished thing.

Spoonbills keep expanding their reach — and building on their great popularity

by Anders Gyllenhaal July 30, 2020

written by Anders Gyllenhaal

The Roseate Spoonbill, once a bird that stuck pretty close to home, is becoming a roaming vagabond.

Forced from South Florida by rising sea levels, deteriorating water quality and poor nesting conditions, hundreds of Spoonbills moved first up both coasts of Florida. Now they’re testing out fresh territories in almost every mid-Atlantic and Gulf Coast state.

They’re turning up in bays and wetlands along the coasts as well as near inland cities and suburbs where they can be a startling sight for unsuspecting birders. Researchers say these forays often lead to nesting colonies in new locations that solidifies their arrival.

Jerry Lorenz

“Once they’ve found a new place, it’s only a matter of time before they’re nesting there,’’ said Dr. Jerry Lorenz, director of research at Audubon Florida and the nation’s leading Spoonbill expert.

With pinkish red plumage and gawky form reminiscent of their dinosaur lineage, the spoonbills have great popular appeal, which is expanding as their reach spreads out. Our package last year on the spoonbill’s move north into Georgia and South Carolina was among the best-read Flying Lesson’s posts ever.

Beverly’s Birding Basics: How to buy your first binoculars

by Beverly Mills Gyllenhaal July 22, 2020

written by Beverly Mills Gyllenhaal

Second of three parts

Over time, birding binoculars will start to feel like a piece of your anatomy. They’ll be attached to your face for hours at a time for years to come. Whether or not you’re going to enjoy birding – and how skilled you can become – depends a lot on your binoculars.

To complicate matters, the price range is wide – from about $120 for the most basic, entry-level pair to nearly $3,000 for the finest birding binoculars on the market today.

“Birding binoculars” are specific to birding because the requirements are, well, very specific.

A little reading helps

My favorite, most easily understood criteria for what constitutes birding binoculars comes from an article on the Audubon Society’s website, written by Wayne Mones, an avid birder since childhood who writes about binoculars for multiple publications.

“Bird-worthy binoculars must focus quickly enough to “get on” a fast-moving bird,” he says. “They must have a field of view wide enough to locate birds rapidly and follow them in flight.

The cover of Audubon’s binocular package. See link below.

“They must also provide accurate color rendition,” Mones continues, “have no observable distortion in the center of the field, and be bright enough to show subtle features in poor light and sharp enough to resolve fine detail.”

Mones really knows his stuff, and the rest of his excellent article explains the technical basics of binoculars such as magnification, field of view and special considerations if you wear eyeglasses. Again, for the entire article, click here.

Beverly’s Birding Basics, a new feature on Flying Lessons, is meant to help new birders find their way. Last week, the first post in this series addressed why buying a good pair of binoculars is imperative to a fruitful birding experience. The third part will explore how to make the most of your binoculars. For a full library of Birding Basics links, click here.

Why good binoculars can change your (birding) life

by Beverly Mills Gyllenhaal July 14, 2020

written by Beverly Mills Gyllenhaal

First of three parts: Over three weeks, our posts will focus on the specifics of birding binoculars. Next installment: How to go about buying your first pair, followed by Beverly’s insights on how to use them effectively.

If you’ve never seen a bird through binoculars, you have my envy. Your future holds one of nature’s great wow moments – and one of its greatest ah-ha moments as well.

Remember the first time you saw something under a microscope? Or stars through a telescope? Seeing a bird with binoculars for the first time is just as magical.

Binoculars make even the most muted colors, patterns and textures pop. You can zoom in on facial details and head positions — or what I choose to experience a bird’s personality or even emotions, despite the fact that science doesn’t confirm if birds have them. But the mystery itself gives me goose bumps sometimes.

Of course you get some of this with the naked eye, but binoculars intensify the experience. Have you enjoyed Anders’s photos here on Flying Lessons? He’s able to capture these incredible details thanks to the magnification of telephoto lenses – binoculars of a different sort.

And the wisp of red around the Red-bellied Woodpecker’s beak.

Going from the awe of that first glance to a sustained state of bliss takes practice, and a bit of instruction can help.

Why can’t you just pick this thing up and immediately have nature unfold in all its glorious minutia? There’s a disorientation that comes in the instant your eyes go from a wide, faraway view to such a close-up view. It scrambles your brain. The bird has lighted on a branch, but you’re focused on a nearby pine cone. By the time you figure it out, that bird is gone.

A good pair of beginner’s birding binoculars costs between $250 and $300.

You can tune in on the daily chores of birds, such as this Tufted Titmouse scarfing up breakfast.

Are you surprised? Many people are. Before you settle for those dinged-up binoculars your grandpa used in the war or the $50 ones from your kid’s field trip, hear me out.

Birding is not something you do once, like going to a gourmet restaurant for the best meal of your life. For that same $275 dinner, binoculars can serve up an exquisite plateful every single day.

For thousands of people, birding is a sport like golf or swimming. For thousands more, it’s a hobby like photography, playing an instrument or sewing.

This Barred Owl’s whiskers are visible.

You aren’t surprised when an aspiring golfer spends $275 on a first set of clubs. Did you know that a beginner sewing machine costs $275, too? You’d be lucky to find an entry-level violin or decent guitar for $275.

To make matters worse, as skills improve and dedication to the sport / hobby of birding deepens, many seasoned practitioners prioritize their way to buying optics that cost 10 times this much. If you’re merely surprised at the idea of spending $275 on binoculars, you’re likely horrified at $2,750.

Or the fluffed plumage of an Indigo Bunting

I am acquainted with many amateur musicians, cyclists, photographers, gourmet cooks and seamstresses who have gradually upgraded their equipment over the lifespan of a leisure pursuit. And to be fair, the first time I heard a friend spent $3,000 on a bicycle, $2,000 for a digital sewing machine or $5,000 on a guitar, what do you suppose my reaction was? Disbelief and horror, of course.

In defense of a hobby’s economic investment, you could earn money from it. Let’s say you play tunes for tips, win a contest, sell your custom-made clothing or hire yourself out as a birding tour guide. Your equipment could pay for itself.

Or you could help others by donating such income to charity.

The tiny tongue of a Yellow-throated Warbler in mid-song

But you might just need to accept the fact that if you’re lucky enough to have disposable income, the ability and the time to pursue a leisure activity, it’s rarely going to be free of charge. And relatively speaking, $275 isn’t excessive and shouldn’t be shocking.

Okay. Now that we’ve established that binoculars are to birding what cameras are to photography, my hope is that you’ll find your way to fairly decent ones and practice using them.

With patience and a bit of luck, God’s most glorious creatures will appear right before your eyes. You’ll never look back.

How the lockdown has helped birds — or has it?

by Anders Gyllenhaal July 7, 2020

written by Anders Gyllenhaal

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.

Arlette Early (right) and Judy Rosengarten at their store in Raleigh, N.C.

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.

Birding Birding Basics Birdsongs

Birding by ear takes plenty of work, but the rewards last a lifetime

by Beverly Mills Gyllenhaal June 24, 2020

written by Beverly Mills Gyllenhaal

Second of two parts

After months of hoping to find this outlaw of a bird, finally, we were close. Very close.

A male Hooded Warbler in Pisgah National Forest / Photos by Anders Gyllenhaal

Coming from a dense stand of old-growth trees in the Pisgah National Forest in Western North Carolina, I could hear this miniature Robin Hood galloping along on his horse. Then he’d toss his hat in the air with a triumphant – but very quick — “Woo-hoo.”

That’s how I visualize the Hooded Warbler singing – three gallops followed by a two-beat, joyous crescendo. It’s is my trick to remember the difference between this warbler’s song and any of his 36 tiny wood-warblering cousins.

If you clump them all together, the 37 warblers that are likely to sing, chip and chirp in the eastern half of the country can make more than a hundred sounds. But the cool thing is, every one of those sounds is unique to just one bird.

When they’re camouflaged by dense foliage, which songbirds often are, the only way to tell if a particular bird is close is to hear it. Suddenly your odds for finding – and photographing — the bird increase exponentially. (For a recording of the Hooded Warbler, click here.)

Like learning a language

At the heart of it, birdsong is a foreign language. Every bird speaks its own, minus the mockingbird and a few other mimics. More than 100 species can be nearby at any given time, depending on the season and habitat. The resulting cacophony at dawn in springtime is beautiful, astonishing and overwhelming.
