How the Northern Cardinal is helping me through the virus crisis

First of two parts

If there’s a singular song of spring, it’s the call of the Northern Cardinal.

That loud, distinctive whistle is often the earliest note of the morning in much of the country. When the full bird orchestra eventually joins in, the Cardinal still holds the first chair.

Ever since the virus chased us all into our homes, I’ve added a morning birding walk under the guise of exercise (a loophole where we live.) It’s an antidote to the uncertainty; the first arrivals of migration are showing up right on cue in eastern North Carolina, while the year-round birds are hard at work gathering food, building nests and pairing up.

Almost everywhere I walk, Northern Cardinals are there to serenade. Their repertoire is rich and familiar, including that flute-like “cheer-cheer” opening, their steady chirps, their staccato zip-zips that sound like something from a video game. It’s not too strong to call it incessant on some days.

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

by Anders Gyllenhaal
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.

“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 for the jays.

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.’’

A Tricolored Heron worthy of the Olympics

by Anders Gyllenhaal
written by Anders Gyllenhaal

It’s a move that seems to defy physics: The Tricolored Heron hovers in midair just above the surface when it dips its neck down and snags its prey from near the surface of the water.

This medium-sized heron is named for its striking collage of blue, purple and white plumage and known for its frenetic feeding dance in shallow water that helps to scare up prey. But if there’s one acrobatic maneuver that tops them all, it’s how the Tricolor will sometimes feed while flying  — a move worthy of the Olympics.

I watched just such a gravity-defying maneuver the other day at a central Florida marsh near Melbourne, where a heavier-than-usual rainfall drew a large flocks to the wetlands. The competition was fierce among hundreds of herons, ducks, gallinules, pelicans and spoonbills.

This young Tricolored Heron was trying out all his tricks.

First it zigged and zagged along the edge of the shore, lunging for prospects as it followed its own obstacle course though the water. Then, apparently unhappy with the results, it lifted off and headed to a new spot. That’s when the heron spotted something near the surface of the water.

It dropped down a few inches until its feet were almost touching the surface. As if walking on the water, the Tricolored reached its long neck down and into the pond and snapped up something for lunch. The show didn’t stop there: The bird never landed, and instead recovered its equilibrium and flew on.

Herons are great fun to watch, particularly the more active Great Blue, Little Blue Heron and Tricolored Heron. As common wading birds that generally don’t mind people, you can study them for hours working the waterways, marshes and sometimes on the beach. The Great Blue can be found all across the U.S. and Central America, and the Little Blue in the Southeast, parts of the Midwest, California and Mexico.

The Tricolored is the hardest of the three to find, more limited to Florida, the Gulf Coast and Central America. But when you do come across one in the midst of its search for food, you may get a performance. This is one bird that deserved a place on the podium.

Here’s a gallery of some of our favorite heron photos, followed by two of Cornell’s range maps of where they can be found. The first shows their range through the year, and the second is an animated version.

How to get started as a birder: Six suggestions from the experts

by Anders Gyllenhaal
written by Anders Gyllenhaal

Somewhere in the inner workings of migratory birds, a signal goes off that tells them it’s time to head north. Is it just our imagination, or do birders get the same kind of inkling as spring comes within reach? Either way, it’s time to get ready for the best part of the year as the early birds are making their moves.

Here’s a recast of our post from last year about how new birders can get started, drawing on experts from  all the leading bird institutions — Audubon, Cornell University’s Lab of Ornithology, and the American Bird Conservancy.

Smithsonian author and ornithologist Bruce Beehler

If you want to be a birder, they all say, there’s no better time to start than now. Every spring, about half of the 650 species in the Western Hemisphere are on the move. From mid-February to mid-June, between 4 and 5 billion birds will fly thousands of miles to reach their breeding grounds.

Bruce Beehler’s book

“The birds are singing, and they have their spring plumage,’’ said Bruce Beehler, a Smithsonian research associate at the National Museum of Natural History’s Division of Birds and author of  encyclopedic book, Birds of Maryland, Delaware and the District of Columbia.  “In the spring, the birds are going to come to you, you don’t need to go to them. They’re going to pass right through your backyard, whether you know it or not. That can be pretty darn exciting.’’

We’ve boiled all of the advice we collected down to six short suggestions for how to get started — as well as how to make the most of the spring migration no matter what level of birder you are:

How did a Great White Pelican fly around the world? Here are some answers.

by Anders Gyllenhaal
written by Anders Gyllenhaal

How does a huge, lumbering bird like the Great White Pelican fly halfway around the world to reach a place like Florida?

It’s a question birders and experts alike have been asking in the weeks since one of these striking, exotic pelicans from Africa and Asia arrived on the Merritt Island Wildlife Refuge south of Jacksonville. Although birds are always turning up in unexpected places, this visit set off a true kerfuffle as word got around.

Our Flying Lessons post on the Great White Pelican drew thousands of views and 600 shares on our Facebook page. With those came an avalanche of questions:

Did this bird fly all the way – or perhaps escape from a zoo in this hemisphere? Will it stay in the area, or find its way back home? Will it upset the balance of nature the way certain non-native plants and animals do? How does a bird get so far off course in the first place?

“I would love to know what his story is,’’ Linda Boccuti wrote on our Flying Lessons Facebook page.

Most of the answers are guesses, since the bird wasn’t tagged and certainly isn’t talking. But Andrew Farnsworth, a research associate with the Cornell Lab of Ornithology who specializes in migration, said the likely drivers are genetic migration instincts that go off track, lack of food back home and changing weather patterns that are becoming more frequent around the globe.

Floridians and their Scrub Jay: Can they coexist?

by Anders Gyllenhaal
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.

How an invisible bird is saving the rainforest

by Anders Gyllenhaal
written by Anders Gyllenhaal

In almost every interview with scientists and researchers, a question comes up about why birds are important to people. One of the most compelling answers I’ve ever heard came in an interview for a piece running in the Washington Post this week exploring the powers of bioacoustic research. 

A Puaiohi Thrush (Photo by Lucal Behnke; cover photo by Behnke as well)

The bird in question was the Puaiohi Thrush, the last few hundred of which live so far up in the cliffs on the Hawaiian Island of Kauai it’s almost impossible to see them. To try to save them, a team had to turn to special recording devices placed at the foot of the cliffs to study their range and breeding.

But why is it important to save a bird that you never see in a place people cannot even get to?

Lisa “Cali” Crampton, who manages the Kauai Forest Bird Recovery Project, said while you rarely see the Puaiohi, its work is spread all across the island. That’s because these thrushes are one of the primary fruit eaters, which then in turn spread the around the island.

“I would hate to see us have to save only one bird, but it would be the Puaiohi,’’ she said. “We have no forest without the Puaiohi. Without forests we have no flood control. We have no drinking water. The forest is the backbone of these islands.’’

Not every bird plays such a pivotal roll. But all perform some part of the interlocking operation of nature, from pollination to pest control. 

Many people who study birds will talk about their profound beauty, or how they serve as an indicator of the environment. I love the Puaiohi story because it illustrates in such concrete terms what the impacts would be if species disappear the way many recent studies are predicting.

This week’s story in the Post is about how bioacoustic technology — basically capturing bird songs and calsl and then using technology to analyze the results — has advanced to become a powerful tool for learning about birds. Together with new uses of radar, citizen science and big data, bioacoustics helps uncover more about the complexities and threats to birds than ever before.

That knowledge makes it steadily more obvious that birds are both creatures of miraculous beauty and natural engineers that are fundamental to a healthy and functioning environment. 

That research also provides solutions for how we can keep species like the Puaiohi on the job of building the rainforests. We’ll save the details of that rescue plan — as well as many other breakthroughs from bioacoustics — for the story. Here is a link to both the Washington Post piece and a list of rescue projects using bioacoustics around the globe.

Hummingbirds on the move: Evolution on fast-forward

by Anders Gyllenhaal
written by Anders Gyllenhaal

A few weeks ago, dozens of readers from around the country shared their hummingbird stories on our Facebook page after we ran a post on the growing numbers of the tiny birds that are skipping migration and staying in the U.S. for the winter.

Birdwatchers from Michigan to Texas, Seattle to North Carolina reported seeing the birds stay longer into the fall, and sometimes through the winter in the warmer states. Randell Fleet of Houston seemed to speak for everyone when he said: “I hope they’ll be OK.’’

Ruby-throated Hummingbird

The outpouring made us want to know more about what was going on. So we talked with scientists and researchers around the country who specialize in hummingbirds. The story that emerged, which is running in The News & Observer of Raleigh this week, is not just about the changing migration of hummingbirds.

It’s also a look at modern-day evolution on a fast-forward speed as birds struggle to adjust to their altered environments. The story focuses on North Carolina, because this is where a lot of the action is. But hummingbirds, particularly Ruby-throated and Rufous, are starting to stay the winter all along the southern Atlantic coast and down through the Gulf states.

Hummingbird researcher Susan Campbell explaining how she bands the tiny birds

“It’s a really fascinating subject,’’ said Scott Weidensaul, an author and researcher who’s one of the country’s leading experts on hummingbirds, “one that ties together a couple of important threats, including climate change and the adaptability of birds in the face of change.’’

One part of the story we found particularly intriguing, which we couldn’t delve too deeply into in The N&O piece, is how this break with the migration pattern places a spotlight on exactly how birds adjust – and how a pivot like this can play out for generations to come.

Nobody can say when the first hummingbirds decided to skip the long and arduous fall trip to the tropics. I loved the comment by the Audubon Society’s Geoffrey LeBaron, head of the Christmas bird count, who said: “If you don’t have to fly across the Gulf of Mexico, why do it?’’

Third major report in succession establishes a new era of bird research

by Anders Gyllenhaal
written by Anders Gyllenhaal

We spent many hours during the last spring migration at the crest of Washington D.C.’s Rock Creek Park, hanging out with some of the area’s most experienced birders waiting to see what species would appear next.

When the mornings were slow, the conversation sometimes turned to how unpredictable the migration has become: Some days would be as quiet as July, and others suddenly filled with a flurry of unexpected migrants flying through.

Species in today’s study include many warblers, songbirds and wading birds, such as this Whimbrel. Photo from Cornell Lab by Kyle Horton. Cover photo of Long-billed Curlew is by Nick Saunders.

For years, birders around the country have watched the evidence gather that the bird world has been disrupted.

But this fall, three scientific reports in succession, including a major study released today, have fundamentally altered the picture of what’s happening. Modern technologies are enabling a new level of research about birds, migration, breeding and populations with a precision not possible just a few years ago.

Today’s study is the first to document how birds are starting their spring migration journeys a great deal earlier to keep up with climate change. And while migratory birds are trying to adjust, the research based on 24 years of weather radar data suggests that the intricate balance of when plants flower, insects arrive and birds start breeding are falling out of sync for some of these species.

“How bird populations respond in an era of such rapid and extreme changes in climate has been a black box,” said Andrew Farnsworth, a co-author of the migration study and researcher at the Cornell Lab of Ornithology. “Capturing scales and magnitudes of migration change over time has been impossible until recently.”

Here are some of the Cornell Lab photos of species that are part of the migration research:
