When the shorebirds called Lesser Yellowlegs sense a threat to their nest, they’ll put up an unforgettable racket to drive the danger away. Smaller and with a shorter bill than the Greater Yellowlegs, Lesser Yellowlegs sing to attract mates, while flying or perching up in a tree like a songbird. Although they’re widespread, Lesser Yellowlegs have lost over half their numbers in the last 50 years. Protecting wetlands, addressing climate change, and using sustainable farming practices can all help make sure that this species stays common, loud and proud throughout the Americas.More info and transcript at BirdNote.org. Want more BirdNote?

For most birds, keen eyesight is critical for survival. But many birds lead lives that can be very hard on the eyes — like flying at breakneck speed, racing for cover into a dense thicket, or diving under water to capture prey. Imagine how the chips fly as this Pileated Woodpecker chisels a cavity. Fortunately, birds have evolved a structure for protecting their eyes. Beneath the outer eyelids lies an extra eyelid, called the nictitating membrane. It helps keep the eye moist and clean while guarding it from wind, dust, and hazards.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Fresh-fallen snow is beautiful, but it poses a challenge to birds. The ground where they found food is now covered by several inches of snow. Birds such as juncos and other sparrows flit under bushes where snow doesn’t cover the ground. Finches and chickadees pick at the seed heads of plants sticking out above the snow, while robins (like this American Robin) seek out dried fruits. Nuthatches and woodpeckers cling to trees as they search for insects within the bark.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

On a winter morning in Costa Rica, a colorful choir welcomes the day. A pair of Bay Wrens sings a brisk duet just before sunrise. Perched in the upper canopy of the tropical lowland forest, a group of Keel-billed Toucans calls out. In a nearby tree, Purple-throated Fruitcrows (like this one) add their voices to the chorus. Then a male Montezuma Oropendola belts out an electrifying series of notes — one of the most distinctive voices in the tropics. Finally, a Bright-rumped Attila calls from its perch.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

In several neighborhoods of Sydney, Sulphur-crested Cockatoos have learned ways to open trash bins and grab some leftover food. Researchers found that birds in a given suburb seem to learn their trash bin opening technique from nearby birds, leading to subtle differences in how cockatoos raid the garbage throughout the city. This has pitted two highly intelligent species against each other as people have tried to come up with deterrence methods to keep birds away from the trash.More info and transcript at BirdNote.org. Want more BirdNote?

Sam ‘Ohu Gon was one of the last people to see an ‘Ō‘ū, a native Hawaiian bird that’s presumed to be extinct. He’s worked at the Nature Conservancy of Hawai‘i for nearly forty years. In 1988, he took part in an Audubon Christmas Bird Count, hoping to encounter critically endangered native birds.More info and transcript at BirdNote.org. Want more BirdNote?

Birds have many ways of showing affection for their partners. One way is allopreening, where a bird uses its bill to groom a mate, twirling each individual feather in its beak (like these Macaws). Other birds present their partners with gifts like moss or sticks. A female Arabian Babbler might reciprocate with a gift of her own — or just cut to the chase and lead her suitor to a rendezvous spot in the shrubbery.More info and transcript at BirdNote.org. Want more BirdNote?

The Keel-billed Toucan, also known as the Rainbow-billed Toucan, looks like a bird with a giant banana for a beak. They have a black body, a yellow patch from the face to the breast, and a huge rainbow-colored bill. The big beaks have more than one use: they can be used for fighting with rivals, but they can also help toucans regulate their body temperature in the tropical heat.More info and transcript at BirdNote.org. Want more BirdNote?

The American Robin and the Baltimore Oriole both have cheery, upbeat songs. At first, you might think there’s no way to tell these two cheery, upbeat singers apart. But there are a couple of differences. American Robins usually have a longer song, while Baltimore Orioles usually stop after a phrase or two. Plus, Baltimore Orioles sound sweeter and more melodic than American Robins, who can come across a little screechy at times.More info and transcript at BirdNote.org. Want more BirdNote?

When the bitter cold of winter arrives, songbirds face an emergency: how to keep warm through the night. On normal nights, many prefer sleeping solo in a sheltered spot. But in severe cold, some kinds of birds may have a greater prospect of survival by roosting with others.More info and transcript at BirdNote.org. Want more BirdNote?

Trumpeter Swans weigh over 25 pounds and measure about five feet from beak to tail. They were nearly hunted to extinction by the turn of the twentieth century. In Arkansas, a small flock of Trumpeter Swans began spending the winter at Magness Lake in the 1990s. It has now grown to one of the biggest winter swan flocks in the Southeast. In recognition of its value to the swans, Magness Lake has been designated an Important Bird Area.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

In some parts of North America, Sandhill Cranes are common as ants at a picnic. In New England, on the other hand, they’ve been almost as rare as pterodactyls — until relatively recently! Birders began reporting cranes scattered throughout the region. When a Sandhill Crane chick hatched in Maine in 2000, it was evident the New England birds were not just strays. Cranes now breed in several parts of New England, especially Massachusetts.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Do you ever see flocks of birds in your yard that show up in droves one year, but are completely absent the next? Some nomadic species such as Pine Siskins move based on the availability of food and habitat. It’s called “irruptive” migration, and it sometimes leads to backyards full of siskins. While these flocks are a delight for bird watchers, the dense groups can easily transmit diseases such as salmonellosis.More info and transcript at BirdNote.org. Want more BirdNote?

Roads can get people where they need to go. But they often run right through wildlife habitat, creating a deadly hazard for animals on the move. Liz Hilllard, who’s the Senior Wildlife Biologist for Wildlands Network, says roadkill takes a huge toll on birds and other animals every year. Wildlands Network helps transportation agencies create wildlife-friendly designs and build animal-centric bridges and tunnels for their safe crossing. The goal is to create a connected landscape that Liz and her colleagues call a wildway.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Brown-backed Solitaires are ordinary-looking: medium-sized, gray-brown birds. But they have one of the most melodic, complex songs in the world, ringing out year-round in high-altitude forests from Mexico to Central America.More info and transcript at BirdNote.org. Want more BirdNote?

Look for the stories birds tell with their tracks in the snow. A crow swaggers, leaving right-and-left steps much as a walking human would. Juncos under a birdfeeder leave a hopping pattern of tiny footprints in side-by-side pairs. Look for beak marks, where a bird picked up a choice morsel or probed the ground. Tell-tale signs sometimes tell stories of life and death. You might see mouse tracks end suddenly, just where you find the imprint of an owl's wings. Find out more about animal tracking at the Wilderness Awareness School.

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.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

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 BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

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?
