This American Robin has caterpillars and an earthworm in its beak. But which food source is the real prize? Everyday earthworms are higher in protein than beef or chicken. You’d have to eat about a pound of soybeans to equal the protein in just three ounces of earthworms. They’re also high in calcium and easy to catch, compared to crickets or butterflies. Put all that together and you have a superfood for birds — especially the youngsters.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

When we think of a bird to represent peace, many of us might think of doves. Deja Perkins, an urban ecologist, says that the Wood Thrush is the bird that best represents inner peace and peace of mind.More info and transcript at BirdNote.org. Want more BirdNote?

One bird of prey may steal another's meal, a behavior that biologists call piracy, or kleptoparasitism. The prey may change hands several times, perhaps from Northern Harrier to Peregrine Falcon to Bald Eagle. The Peregrine - like the one seen here - may steal a meal, or have its meal stolen, or both! Visit your local Audubon chapter, to see where you might watch raptors this winter.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Attu, at the western end of Alaska’s Aleutian chain, is home to the Rock Ptarmigan. Although grouse are not long-distance fliers, Rock Ptarmigans can cross open water, so they occur from one end of the Aleutians to the other. They are supremely adapted for high latitudes, with thick feathers, each with two shafts. During winter, even their toes become feathered. They ride out blizzards by burrowing deeply into fresh powder snow and roosting there. When spring finally arrives, the snow-white male will flutter into the air, then glide to earth while calling loudly. He fans his black tail in spectacular display before the female. And a new year begins!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Judy Pollock, the founding president of the Bird Conservation Network, says the Chicago area is crucial to birds, and has a grassroots conservation movement that supports many nature preserves. With a team of more than 200 volunteers, the Bird Conservation Network conducted 22 years of surveys to better understand the birds nesting in the Chicago metro area. The surveys showed some troubling declines but also showed signs that diverse habitats in the area are helping keep birds around.More info and transcript at BirdNote.org. Want more BirdNote?

It turns out, a raven's black plumage works quite well in the desert. Black feathers do conduct the sun’s warming rays, but they concentrate that solar heat near the feathers’ surface. All it takes is a breeze from the wind, or from flying, to move all that heat away from the surface of the feathers.More info and transcript at BirdNote.org. Want more BirdNote?

The Scaly-breasted Wren lives in Central and South America, and has a lengthy song of whistled notes separated by pauses. By analyzing song recordings, researchers found that Scaly-breasted Wrens can precisely measure out pauses  — even as they increase to several seconds. The findings suggest that the wrens have an internal metronome as accurate as a highly-trained musician playing a solo.More info and transcript at BirdNote.org. Want more BirdNote?

A pint-sized Northern Pygmy-Owl, not much bigger than a pine cone, hoots from a tree-top on a winter morning. Before long, this diurnal owl - a determined predator of small birds and mammals - will attract a mob of a dozen or more small birds. Mobbing may be a collective response to danger. But it's not certain if the "mobbers" hope to drive away the predator, or simply draw attention to the threat.More info and transcript at BirdNote.org. Want more BirdNote?

Skateboarder and birder Dave Mull remembers the first time he heard a Steller’s Jay imitating a Red-tailed Hawk. “These Steller's Jays were pretending to be something they were not, kind of tricking the world,” he says. It got him into the mindset that he could attempt a terrifying new skateboard trick called the “stump jump.”More info and transcript at BirdNote.org. Want more BirdNote?

For today’s bird walk, we’re going to need binoculars, sunscreen, hiking boots, annnnnd a time machine. Let’s set our course for the late Cretaceous Era, 65 million years ago. Stay alert! There are dinosaurs all around us, of all sizes — and appetites — including some of the earliest birds, like this Ichthyornis.More info and transcript at BirdNote.org. Want more BirdNote?

During winter, the Greater Sage-Grouse is wholly reliant on its namesake species — sagebrush — for both shelter and for food. Scientists call this bird "sagebrush obligate," meaning it needs this plant to survive. In the spring, its diet shifts to insects and plants, as it gets ready for the most fantastic mating show in the west — the lekking season.More info and transcript at BirdNote.org. Want more BirdNote?

These Downy and Hairy Woodpeckers appear nearly identical, but the Hairy Woodpecker is larger than the Downy, with a distinctly longer bill. And it doesn't have the black spots on its outer tail feathers like the Downy. But even if you can’t observe these spunky birds, you can identify them by listening carefully. The call of the Downy Woodpecker is soft and downy, like a duvet. The call of the Hairy Woodpecker is loud and hairy, like a heavy metal band!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Clark’s Nutcracker is a clever corvid that has a special relationship with a tree called the whitebark pine. The tree’s cones don’t open on their own, and Clark’s Nutcracker is one of the few species that can pry them open. When the nutcrackers cache the seeds for the winter, they’ll leave a few behind, helping spread the next generation of whitebark pines. More info and transcript at BirdNote.org. Want more BirdNote?

For most birds, wings are for flying. But for Rock Pigeons, they’re also for clapping. When the pigeons erupt into flight, some may slap their wings together above their bodies in a “wing clap.” A male Rock Pigeon will also do this when courting. Short-eared Owls, like this one, have evolved wing-clapping, too. When a male displays to a female or attempts to warn off an intruder, he snaps his wings together below his body in a burst of two to six claps per second, producing a sound that sounds remarkably like . . . applause.More info and transcript at BirdNote.org. Want more BirdNote?

Just off the southern coast of Iceland, the Westman Islands are home to many of the country’s several million Atlantic Puffins. When puffin hatchlings, known as pufflings, get confused by the lights of the city, volunteers of all ages search for wayward pufflings on the street and bring them in for health checks. After the puffins get the green light, the volunteers release them along cliffs and beaches.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Early this fall, the tiny Wilson's Warbler began its long migration to Belize, where it winters. Navigating by the stars, the 1/4-ounce bird made a series of night flights spanning more than 2500 miles. This warbler returns to the same coffee plantation each year. Taller trees that shade the coffee are a winter home for many migrants from North America.By buying shade-grown coffee, you can help migratory birds, including the Wilson's Warbler.More info and transcript at BirdNote.org. Want more BirdNote?

By December, an array of diving birds that nested at far northern latitudes are wintering on temperate waters across the continent. If we could watch them under water, we'd see this Common Loon racing like a torpedo. A goldeneye dives under water and swims about 10 feet from the surface, while scoters get down to 30 feet in search of clams and mussels. But if one bird stands out as the most beautiful diver, it has to be the Long-tailed Duck. Propelling itself beneath the surface with its wings, it seems to fly through the water, sometimes to depths of more than 60 feet!More info and transcript at BirdNote.org. Want more BirdNote?

Birds are resourceful. Wherever they live, even in the biggest cities, they find clever places to build their nests. An initiative from the Cornell Lab of Ornithology called Celebrate Urban Birds, once asked people to share the funkiest and funniest places they’ve seen a bird nest. Among the highlights were a family of robins set up shop in a coiled cable hung near a welding rig, a wren nest in an old car motor, and a tiny hummingbird nest perched precariously on an outdoor string lightbulb.More info and transcript at BirdNote.org. Want more BirdNote?

The boreal forest stretches across Canada and Alaska, a huge expanse of woods, wetlands and wilderness. And it’s full of magnificent forest owls that depend on mice and other rodents for food. Those populations can boom and bust, so in lean years, hungry owls often fly as far south as the northern U.S. to find food.More info and transcript at BirdNote.org. Want more BirdNote?
