On a hot summer’s day, watch a bird such as a crow — or this Bald Eagle — very carefully. You’ll never see them sweat, because birds don’t have sweat glands. So how do they keep cool? One way is panting. As the bird breathes rapidly, heat is carried out of its body through the lungs and air sacs. Bare skin on the legs, face, and beak also help with cooling. So do puffing out feathers, fluttering w...

The Tower of London has a long and notorious history of murderous political intrigue, dungeons, and famous beheadings. And for more than 300 years, the tower has also been home to a set of royally maintained ravens. Since the time of Charles II, at least six ravens have — by royal decree — made their home in the tower. They are given ample food, comfy quarters, and private burials in the moat near...

Brown Pelicans fly just above the surface of the water. They circle high, then diving headfirst, plunge under water to catch fish. But doesn't that hurt? Several adaptations protect pelicans as they dive. First, they have air sacs beneath the skin on their breasts, which act as cushions. Pelicans have also learned that a steep dive angle, reduces aiming errors caused by water surface refraction. M...

Gambel’s Quail and California Quail are both well known for the comma-shaped tuft of inky black feathers poised atop the crown of their heads. For both species, this decorative “topknot” is formed from six individual feathers that contour together into a single structure. Yet they’re hardly the only quail with a fashionable updo. Though we don’t know exactly why so many quail evolved elaborate hea...

By late summer, the male Mallard’s need for fancy feathers to attract the females has passed. These birds have molted, and their bright feathers are replaced with mottled brown ones. Subdued colors help camouflage the male ducks, protecting them from predators. Come fall, the male Mallards will molt again and become the colorful dandies we remember.

Burrowing Parakeets excavate deep nest tunnels in sandstone and limestone cliffs in Argentina and Chile. The colony’s many tunnels zigzag and interconnect, creating an intricate labyrinth. Their nesting colonies are among the largest of any parrot — one in Argentina has 70,000 birds! ¡Escuche este episodio en español aquí! More info and transcript at BirdNote.org . Want more BirdNote?

Most birds possess the ability to see color. But birds can also see in the ultraviolet spectrum! Hummingbirds — like this Violet-crowned Hummingbird — may zero in on certain flowers because their petals strongly reflect in the ultraviolet range. Migrating birds may use ultraviolet light to navigate on overcast days, because the sun's ultraviolet rays pass through the cloud cover. This episode is s...

Found in Australian forests, male Superb Lyrebirds can mimic calls well enough to convince the bird they’re imitating that the lyrebird is one of their own! While males sing to attract mates, females imitate the calls of predators, which could help frighten other birds off their territories. Listen to this episode in Spanish here .

National Battlefield Parks are grassland habitats worth writing home about. Tall grassy fields aren’t typically considered beautiful, much less valuable to conserve. But battlefield monuments and military parks are maintained as historic sites, with the side-effect of preserving excellent habitat. Today, rather than the roar of cannons, battlefields like Gettysburg, Antietam, and Monocacy are fill...

Brooklyn’s Prospect Park covers more than 500 acres — many of them covered in trees. One bird species that calls the park home is the strikingly beautiful Blue Jay, which nests, forages, and roosts in trees. In the eastern U.S., you can invite Blue Jays into a small yard with just a decent tree or two. It’s the volume of branches and leafy habitat overhead that matter to the jays. More info and tr...

If you’re trying to spot a bird, you should look up — right? While it’s true that there are many beautiful birds to see in the sky, plenty of species are easier to find by keeping your eyes and ears to the ground. You may encounter towhees using their powerful feet to kick up leaf litter beneath dense underbrush. American Pipits and small shorebirds often look like clods of mud before they start r...

The Steller's Jay is a jay... and it's blue. But it's not a true Blue Jay with a capital "B." The bona fide Blue Jay is primarily a bird of eastern North America. Blue Jays and the Steller's Jays have similarly raucous personalities. Like their larger cousins, the crows, ravens, and magpies, they are intelligent opportunists.

At the close of a summer day, the songbirds go silent. As if on cue, the birds of the night make their voices known. In an Eastern woodland, the eerie trills and whinnies of an Eastern Screech-Owl are among the first sounds of the night. Meanwhile, as night falls west of the Rockies, a Western Screech-Owl calls out. But there’s another bird whose voice will drown out the loudest of screech-owls: t...

The Ross’s Gull is a dainty seabird that’s rarely found south of the High Arctic. Though their bodies are mostly gray, their breast feathers and underparts glow a satiny pink thanks to pigments from the marine crustaceans they pluck from the ocean’s surface. Every so often, a Ross’s Gull drifts into southern Canada and the U.S. — and almost always attracts an adoring crowd. More info and transcrip...

By August, many birds have just completed the intense rigors of nesting and raising young and now undergo a complete molt. Molt is a cyclic process of feather growth. As new feathers grow in, they push the old ones out. Why molt? Because feathers wear out. Songbirds that migrate long distances need to complete this process on a tight schedule, to be ready when it's time to strike out in September....

Many bird species can eat the fruits of plants that are toxic to humans — even the white berries found on poison ivy. These birds just aren’t sensitive to the compounds in the berries that are irritating or poisonous to people. While you probably want to stay away from poison ivy, you can improve habitats for birds by planting native fruit bushes and advocating for wildlife-friendly gardening in p...

Some believe the song of the Wood Thrush to be the most beautiful bird song in North America. Others select the song of the Hermit Thrush. Still others name the singing of the Swainson’s Thrush. How do thrushes like this Veery create such fine music? The answer is that the birds have a double voice box, unique to them, called the syrinx. A fine singer like a thrush can voice notes independently an...

At Charity Birds Hospital, a small staff takes care of approximately 2,600 birds at a time, providing antibiotics, medicine, food, and a safe place to rest for injured or sick birds. The hospital is run entirely on donations, mostly from the Jain community, which follows the philosophy, “live and let live.” More info and transcript at BirdNote.org . Want more BirdNote?

Canyons, whether large or small, can host a spectacular variety of birds! Consider Swakane Canyon, in central Washington State. It cuts west from the Columbia River into the Entiat Mountains for nine miles, while gaining nearly 3,000 feet. Steep slopes wall in the canyon floor, several hundred yards wide. A slender creek runs through the canyon, nurturing shrubs like blue elderberry. The plant pro...

In the rural Southeast, roadside ditches – known as “bar ditches” – carry on for miles. The term bar ditch probably comes from their construction, when dirt was "borrowed" to build up the road. The ditches are full of water and full of life, these narrow wetlands. Herons stalk the shallow water, stabbing at minnows. Common Gallinules, like this one, swim on the surface. Reeds and bulrushes provide...

For as long as humans have been solving problems, we’ve looked to nature for inspiration. In some cases we’ve even imitated other organisms in our inventions through a process called biomimicry, says Billy Almon, a futurist and biomimicry expert. Billy discusses how the Wright brothers modeled their early airplane designs from the flight mechanics of turkey vultures and how there’s still a lot we...

In June of 2022, Adé Ben-Salahuddin worked as a volunteer research assistant on a tiny island off the coast of Maine at a Common Tern breeding colony. Every once in a while, the colony would suddenly go dead silent as all the adult terns took flight and dove over the rocky cliffs, returning soon afterward. This strange behavior is called a “dread,” and sometimes occurs without a predator nearby. I...

Bird nests can be hard to find, often hidden in plain sight. Is the clever camouflage simply the result of using building materials that the birds happen to find? A Scottish research team used birds popular in the pet trade, Zebra Finches, to try and find out. The team gave nesting Zebra Finches two sources of paper to build their nests from: one that matched the papered walls of their cage, and o...

The Florida Keys extend from the state's peninsula like a string of pearls, and pearls they are, in their uniqueness and value. Stands of hardwood trees rise above the islands' level ground. These trees draw many birds of the Caribbean to the keys' tropical habitat. One of these is the White-crowned Pigeon. It's a fruit-eater that eats native figs and the fruit of the poisonwood tree. White-crowns...

Migratory birds connect the Northern Plains with many parts of the Western Hemisphere. Lark Buntings, Baird’s Sparrows, Upland Sandpipers, and many other birds winter from Central to southern South America. But their reproduction depends on the bounty of the prairie spring. Disrupting any part of their annual life cycle — breeding habitat, stopover places during spring and fall migration, and wint...
