Birdnote

A flock of shorebirds flying wingtip to wingtip seems to act like a single organism, rolling and twisting in exquisite patterns. Flocks like these use a combination of two organizational patterns. One is a “cluster”: lots of birds flying together in a loose, three-dimensional cloud. The second is a basic V-formation, where smaller groups of birds within the flock sync up in V-shapes, like migrating geese. Voilà! Predator avoidance and aerodynamic efficiency.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Birds were one of the earliest subjects for human artists. A cave painting in France over 30,000 years old shows the unmistakable outline of an owl. Paintings on Ancient Egyptian palaces and tombs feature birds with intricately detailed flight feathers, colors, and postures, allowing researchers to identify the species thousands of years later.More info and transcript at BirdNote.org. Want more BirdNote?

When a hawk is about to capture a songbird, the songbird has one last trick: a fright molt. It’s when a bird loses feathers due to sudden stress. This usually involves feathers near the tail or rump, where they’re most likely to be attacked as they flee. It can be a saving grace when the bird is about to be caught — similar to a lizard dropping its tail. There’s a downside to having your tail scared off. A tail helps the bird turn and balance in flight. But if dropping feathers lets the bird live to chirp another day, it’s worth it.More info and transcript at BirdNote.org. Want more BirdNote?

The slim, 4½-inch Blue-gray Gnatcatcher is found over much of the East and Midwest and in parts of the West, too. It actively searches trees and bushes for small bugs to eat, often hovering briefly and flaring a long black-and-white tail.More info and transcript at BirdNote.org. Want more BirdNote?

When a bird of prey flies over, a flock of crows may dive-bomb the predator and give it a noisy escort out of town. An Eastern Kingbird, like this one, will clamp its feet onto the back of a hawk to send it packing. How do they know which birds to chase off and which to ignore? By genetic wiring, or instinct, but also learning. By watching their parents in the act of mobbing, youngsters gain critical knowledge that may save their own skin.More info and transcript at BirdNote.org. Want more BirdNote?

In general, the bigger the bird, the higher the number of feathers. Someone counted the feathers on a Tundra Swan and came up with 25,216. At least 80% were on the swan’s neck. Penguins, on the other hand, have lots of small feathers all over their bodies. The largest species is the Emperor Penguin, and one project counted around 80,000 feathers on a single bird. That’s nearly sixty per square inch – keeping the penguin insulated and waterproof in harsh climates. But the most feathered creature ever? It may have been a dinosaur!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Sam ‘Ohu Gon is the Senior Scientist and Cultural Advisor for the Nature Conservancy of Hawai‘i. He's something of a rare combination: academically trained in conservation biology as well as traditionally trained in Hawaiian chant and ceremony. Sam's work tries to bridge traditional Hawaiian knowledge with conservation to ensure the remaining species stay with us.More info and transcript at BirdNote.org. Want more BirdNote?

Visit a shallow wetland in summer, and you might see this slender, black-and-white shorebird with outrageous red legs. The Black-necked Stilt uses its long legs for wading as it feeds on tiny insects and crustaceans on the surface of the water. Stilts are sensitive to drought, which has increased with global climate change. But they readily move to new breeding areas and respond quickly when new wetlands are created.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

By carrying more people in a single vehicle, mass transit can use less energy than cars. Taking steps to reduce greenhouse gas emissions can help the hundreds of bird species put at risk by climate change. Not to mention, you can do a little birding on the commute – on the way to the bus or train stop, and on the ride itself.More info and transcript at BirdNote.org. Want more BirdNote?

Black-crowned Night-Herons feed primarily on fish, but they will consume everything from earthworms to clams to eggs of nesting birds and refuse at landfills! Because they are high on the food chain, found throughout much of the world, and nest in colonies, Black-crowned Night-Herons can tell us a lot about the health of our environment.More info and transcript at BirdNote.org. Want more BirdNote?

Shorebirds' lives take them to many places other than the shore. Most of the shorebirds we see along our coasts migrate to the Arctic in summer. Here, many nest on the tundra, some along rushing streams, and others on rocky mountainsides. Long-billed Curlews winter on the Florida, Gulf, and Pacific coasts. But this one was seen in a field near Creston, BC, Canada, nearly 500 miles from the coast and 1/2 mile from the nearest body of water, the Kootenay River!More info and transcript at BirdNote.org. Want more BirdNote?

The rainforests of Eastern and Northeastern Australia harbor many species of birds found almost nowhere else. This Eastern Whipbird — which is more often heard than seen — hangs out in the dense understory. Easier to lay eyes on is the large, pigeon-like Wompoo Fruit-Dove. Feathered in a stunning combination of green, purple, and yellow, this bird is clearly named for its voice. And a pig-like grunting on the forest floor tells us we’re in the company of the Southern Cassowary. Its helmet — called a casque — makes it look as much like a dinosaur as any living bird.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Over the last few years, writer Emily Raboteau has been going out and photographing a series of bird murals found throughout New York City commissioned by the National Audubon Society. One day, she came across an artist finishing up a Gray Hawk mural in west Harlem. The artist explained that she had chosen to paint that species because the gray feathers reminded her of the color of her mother’s hair.More info and transcript at BirdNote.org. Want more BirdNote?

In Texas, Pennsylvania, and elsewhere, people have reported seeing Northern Cardinals that are red on one side and brown on the other, indicating that a bird is half male and half female. This anomaly occurs in other species of birds, as well, not just cardinals. Insects, too! Scientists call these bilateral gynandromorphs.More info and transcript at BirdNote.org. Want more BirdNote?

Ornithologist J. Drew Lanham's favorite bird is “the one with feathers.” But here, he shares a few species that have been especially on his mind lately — “selected birds of the moment annotated by why.”More info and transcript at BirdNote.org. Want more BirdNote?

Feathers are amazing structures. But after about a year, constant use and exposure to the elements mean they have to be replaced. So how do you replace the roughly 20 feathers in each wing that are essential to flight? Many species — such as this Common Raven — molt just a few feathers at a time so they can still fly. But waterbirds like ducks and loons molt all of their flight feathers at once. As a result, they’re earthbound and vulnerable to predators for a month or more — until their full suite of feathers has been completely restored.More info and transcript at BirdNote.org. Want more BirdNote?

Today kicks off Coral Reef Awareness Week. Coral reefs are hotspots of biodiversity, but they’re threatened by warming ocean temperatures, pollution, and overfishing. One thing to be aware of this week is how these underwater ecosystems are linked to birds in the skies above them. And seabirds that nest near coral reefs are a great source of nutrients that can help coral reefs recover faster from bleaching caused by oceanic heat waves.More info and transcript at BirdNote.org. Want more BirdNote?

This American Kestrel evolved to nest in tree cavities or small caves in cliffs. We humans have made life difficult for kestrels. Development has shrunk the open spaces they need. We’ve cleared away dead trees they rely on for nests and sprayed pesticides that eliminate the insects the birds eat. But we humans are also in a position to help. Volunteers are helping to build and put up nest boxes, improve habitat, and monitor these cool little falcons. Together, we can #BringBirdsBack.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

A movie runs at 24 frames per second, just right for humans to sense as normal speed. Pigeons process the visual world several times faster. The frantic car chase that puts us at the edge of our seats would likely appear — to a pigeon — more like a slideshow or PowerPoint. A bird’s rapid-fire perception is vital to its staying alive, whether it’s hunting fast-moving prey or eluding speedy predators. From the pigeon’s perspective, humans live in the slow lane.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Many people would tell you that hearing birdsong puts them in a good mood. Recently, scientists have tried to put numbers to this effect that many of us have noticed. One study found that people who spent a few minutes immersed in the sounds of birds had lower levels of paranoia and anxiety than those who only listened to traffic noise.More info and transcript at BirdNote.org. Want more BirdNote?
