The emphatic hoots of a pair of Barred Owls resonate in the still of a winter's night. Like many owls, Barred Owls initiate their vocal courtship in winter. And they're among the most vocal. These owls have more than a dozen calls, ranging from a "siren call" to a "wail" to a wonderfully entertaining "monkey call." Barred Owls are among the largest owls in North America.

The Wandering Tattler is one of the few birds equally at home along the coast and high in the mountains. They’re found far and wide along Pacific shores, living up to their “wandering” name and gaining names in many local languages throughout the ocean basin. Their nesting habitats in the mountains of Alaska, western Canada and eastern Russia were a mystery for many years. Despite their wide range, there could be as few as 18,000 Wandering Tattlers left in the world. More info and transcript at ...

Bluebirds can bring flashes of azure color and mellow songs to where you live. The best way to bring them close to home is with nest boxes. You’ll need an untreated wood box with a one-and-a-half inch hole five feet above the ground. Finding the right place for the nest box is important, too. Shrubs that bear small fruits can entice bluebirds. Find instructions for building an effective bluebird nest box below. More info and transcript at BirdNote.org . Want more BirdNote?

Most baby birds are adorable little floofs — but not all of them. The tongue and palate of estrildid finch chicks are strangely spotted and ringed. They display these markings while they beg for food. Most species’ chicks have mouth markings in colors ranging from black or white to bright yellow, orange, red or blue. The function of these markings has long puzzled scientists. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter. Sign up for BirdNote+ ...

In 2018, paleontologist Daniel Field took a closer look at specimens from an amateur fossil collector. His team used micro-CT scanning, kind of like a high-energy CAT scan, to visualize the encased fossils. They were amazed to find a tiny bird skull: the earliest known fossil record of a modern bird. The skull looks chicken-like in the front and duck-like in the back. The bird may have looked and behaved like a modern shorebird. More info and transcript at BirdNote.org . Want more BirdNote?

Great Horned Owls excel at nocturnal hunting, thanks to their acute senses and stealth — but their feet let them secure squirming prey. The outermost of their four toes can rotate forward or backward, an advantage that most other birds of prey lack, letting them capture animals as large as raccoons. A four-pound owl can take flight with six pounds of prey. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter.

Razorbills, a cousin to the puffin, nest in colonies on cliffs. Before they lay eggs, Razorbills take part in two unique social behaviors. In one, the Razorbills swim round and round in a tight mass, then dive as one. Next, they surface with heads aligned and bills held open. In another behavior, dozens of birds swim in a line, then zig-zag in a synchronized pattern across the ocean’s surface. More info and transcript at BirdNote.org . Want more BirdNote?

Red-bellied Woodpeckers are bold, conspicuous, and vocal, thriving in rural and urban areas east of the Mississippi. Like most woodpeckers, Red-bellieds eat lots of insects. But they also like nuts, berries, and seeds. They can be attracted to back yards with suet cakes, berry bushes, or even a cut orange tacked to a tree trunk. But the Red-bellied Woodpecker retains one element of mystery: its name. The last thing you would likely notice is the blush of rose on its lower belly. More info and tr...

The group of birds called “songbirds” — the perching birds — is incredibly broad. Half the world’s 10,000 birds are in the songbird group, and their range of body sizes is mind-boggling. One of the smallest songbirds in North America is the Golden-crowned Kinglet, barely larger than a hummingbird. The largest is the Common Raven, which is almost two feet long and weighs around three pounds. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter.

Blackbird songs have a strange music. The Red-winged Blackbird can be heard in nearly every marsh on the continent — bold, brassy, and piercing. The songs may not seem musical, but they definitely get your attention. Brewer’s Blackbirds, which live in open habitats like farms and grasslands, make a wet, slap-in-the-face sound. The combined voices of Tricolored Blackbirds — like this one in a California marsh — sound like a snarling catfight. Another Western bird, the Yellow-headed Blackbird, mak...

Whistling as they fly, Black-bellied Whistling-Ducks are gorgeous waterfowl with bright pink bills and legs, chestnut necks and backs, and black underparts. Though most whistling-ducks live in the tropics, Black-bellied Whistling-Ducks are found in the U.S. along the western Gulf Coast and Florida. But they’re expanding their range and have been spotted nesting as far north as Wisconsin. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newsletter.

It's winter, and apples litter the ground. A few still hang, frozen and thawed again and again. Suddenly a flock of hundreds of birds rises from the ground beneath the trees, swarming in tight formation, wing-tip to wing-tip. Bohemian Waxwings are erratic winter visitors from their nesting grounds in the boreal forests of the north. They come in search of fruit to sustain their winter wanderings.

The Tui is one of New Zealand’s most remarkable birds, intelligent and with iridescent feathers. Its down-curved beak fits perfectly into native flowers. But the Tui is best known for its voice. Each Tui’s complex song is slightly different, a colorful mix of musical notes and offbeat sounds. It’s one of the few birds that can imitate human speech — and even accents.

A bird with abnormal white feathers, like this American Robin, may have a genetic condition called leucism. Leucism prevents pigments from reaching some — or sometimes all — of a bird’s feathers. Albino birds are distinctly different and are entirely white with pink skin and eyes. Albinos have trouble making melanin, the pigment in skin, feathers, and eyes.

The call of the Common Loon is a symbol of the far north. But the species once nested as far south as southern New England, Ohio, Iowa, and California. Human activity and changes to the landscape in these more populated areas has made it harder for loons to persist. There have been encouraging signs in recent years that Common Loons could make a comeback in the southern parts of their range — with our help. More info and transcript at BirdNote.org .

Groove-billed Anis gather in loose groups. And with good reason. They nest communally. As many as four or five pairs of birds may use one nest, a bulky cup of twigs lined with fresh leaves. When the dominant female ani begins to lay her own eggs, the other females lay simultaneously. Up to 20 chalky white eggs have been found in one nest. All parents share the duties of incubating and raising the young. World Birding Centers and the Rio Grande Joint Venture are striving to protect and restore th...

In the 1990s, eagles in the Southeastern U.S. began dying of a mysterious brain disease. Many years of research identified the culprit: a cyanobacteria that grows on an invasive aquatic plant called Hydrilla — also known as waterthyme. Fish ingested the cyanobacteria, and eagles ate the affected fish. Biologists are now working to contain Hydrilla to prevent more harm to ecosystems. Learn more about invasive plants and their effect on birds, waterways and more on this special season of the Bring...

Birds’ four-chambered hearts run larger than those of mammals, relative to body size, and they are coupled with extremely efficient cardiovascular systems. The energy demands of flight require these adaptations. An exercising human has a heart rate around 150 beats per minute. In contrast, an active hummingbird’s heart pumps at 1,200 beats per minute; a flying pigeon’s heart beats at 600. More info and transcript at BirdNote.org . Want more BirdNote?

Gyrfalcons are the largest falcons in the world, with a wingspan of almost four feet and weighing almost five pounds. The name “Gyrfalcon” derives from an Old Norse word for “spear.” During the summer, you’ll find Gyrfalcons on the tundra, where they feed on arctic birds.

The nuthatch’s beak is all business. Long, slender, sharp: it can pluck a tiny spider from a crevice in the bark or carve a nest hole right through the outer hide of a tree. And the Brown-headed Nuthatch is even known to use tools! Picking up a flake of pine bark in its beak, the bird uses it as a lever to pry up the bark scales on a tree and get to the insects below.

Outdoor cats are one of the biggest threats to birds, killing over a billion a year in North America. And indoor-outdoor cats live much shorter lives than indoor-only cats. So keeping a cat indoors helps protect birds. And there are plenty of ways to make the “great indoors” more exciting for your cat. In this episode, BirdNote producer Mark Bramhill shares his experience with his cat, Pigeon, who enjoys a ‘catio’ — cat-patio — and walks on a leash. More info and transcript at BirdNote.org . Wan...

The Common Murre is among the few species of birds that can "fly" under water. When above the water, the 18"-long murre must flap frantically to stay aloft. But beneath the waves, with its flipper-like wings partly extended, it is a streamlined, masterful swimmer. Common Murres, black and white torpedoes with feathers, chase down fish even several hundred feet below the surface. Cornell's Macaulay Library offers audio and video of Common Murres.

The Golden-crowned Kinglet weighs six grams, about the same as two pennies, yet winters as far north as Alaska and Nova Scotia. The birds move through the forest in small flocks and feed constantly, taking in enough tiny caterpillars to maintain their internal furnace at 110°F. And their insulation keeps them warm. Their feathers make up 8% of their body weight, equivalent to the weight of the clothing of an arctic explorer. More info and transcript at BirdNote.org . Want more BirdNote? Subscrib...

In the warmer regions of the world’s oceans, large seabirds called boobies plunge headfirst into the water, snatching up fish. But as a booby flies up from the waves with a fish now in its gullet, there may be another big seabird — a frigatebird — with its eye on the booby’s fresh catch. Now begins one of nature’s great chase scenes. Fortunately for boobies, frigatebirds don’t steal all their meals. Most of the time, they hunt their own seafood — perhaps a squid snapped from the ocean surface or...
