Standing less than six inches tall, with gray feathers and big yellow eyes, the Elf Owl weighs less than an ounce and a half — that’s a bit less than a golf ball. But don’t let their size fool you. The Elf Owl hunts beetles, crickets, and spiders, plus the odd lizard or mouse. Even larger prey like scorpions — with the stingers carefully removed — may end up cached in the nest for later dining. Mo...

At sunset, the male American Woodcock – a plump, robin-sized bird – walks slowly on short legs from the cover of the forest to a nearby clearing. After a few sharp calls, the woodcock takes flight. As he spirals upward, slim, stiff feathers at his wingtips create a curious twittering. At the apex of his flight, the woodcock circles, then descends in a slow spiral, putt-putting like a tiny car abou...

Birds evolved not only wings, but many other adaptations that make it possible to fly. Feathers provide insulation, waterproofing, and a lightweight means to become airborne. Birds have honeycombed or hollow bones, reducing body weight. And instead of weighty jawbones and teeth, birds evolved a light and serviceable beak made of keratin. Most birds consume energy-packed foods rich in calories – li...

Zone-tailed Hawks of the American Southwest look a lot like Turkey Vultures. And they often soar among groups of Turkey Vultures. By consorting with vultures, Zone-tailed Hawks gain a distinct advantage as predators. While doves and lizards would quickly flee the flight silhouette of a Red-tailed Hawk, they seem to ignore the shadow of a vulture overhead. So floating among the vultures, Zone-taile...

People often say that spring “bursts” forth. But this seasonal change isn’t like flipping a switch. It’s more like a series of waves breaking slowly. Robins and bluebirds return north in March. During April, more songbirds migrate north from the tropics, adding to spring’s growing chorus. As late as June, birds like Willow Flycatchers and Mourning Warblers arrive from South America. By this time,...

Buying enough birdseed to keep all your backyard birds satisfied can run up a big bill. Homegrown National Park co-founder Douglas Tallamy says growing native plants in your garden can provide a balanced diet for birds. While there’s a misconception that native plants lead to a messy garden, he says native wildflowers, shrubs and trees can provide both splashes of color and nutritious meals for bi...

Tracking devices revealed that Black Swifts spent over 99% of their time in the air during the winter, almost never touching the ground for months. What’s more, the swifts flew to incredible heights, reaching the highest altitudes on nights when the moon was full – sometimes over 13,000 feet! It’s the first time scientists have seen birds changing their altitude along with the cycles of the moon....

Field Sparrows make use of all the warm months of the year by building multiple nests each breeding season. Females will build their first, cup-shaped nest near the ground in dense grasses. As shrubs and trees grow their leaves throughout the summer, they will pick new spots higher off the ground each time — to protect their eggs from mammals and snakes. These birds avoid human activity and they’r...

Like a jazz player beating out a drum roll, a woodpecker uses its bill to rap out a brisk series of notes. Early spring resounds with the percussive hammering of woodpeckers. Their rhythmic drumming says to other woodpeckers, "This is my territory!" We also hear them knocking on wood when they carve holes in trees to create nest cavities or reach insects. For any woodpecker, it’s all about proclai...

Birds are often admired for their ability to fly. But braking just in time to avoid a crash landing is amazing by itself. How does a robin go from full-out flight to a dead stop at a tree? If we could watch in slow motion, we’d see it raising the angle of its wings higher and higher from the horizontal. A hawk dives a bit below where it wants to perch, then pulls into a steep climb, slowing its mo...

Identifying birds by ear means getting familiar with each species’ unique voice. And that means learning the other voices in the ecosystem, too. Squirrels and chipmunks make calls that can sound a bit like bird calls at times. With practice, each species’ voice becomes more distinct and familiar.

Rasheena Fountain studied environmental science and worked at her local Audubon Society. Now she writes about nature and diversity in the outdoors. And what got her interested in the first place? It all started in kindergarten, with a teacher named Miss Beak and the first robin of spring. More info and transcript at BirdNote.org .  Want more BirdNote? Subscribe to our weekly newsletter.

Alison Vilag has worked for half a decade as a fall and spring waterbird counter at remote migration hotspots around Lake Superior. For weeks, every day from sunrise to nearly sunset, Alison is outside in frigid and volatile weather, identifying species from afar and tallying them with a clicker. Working close to the elements puts Alison face-to-face with the reality of dwindling bird populations....

The world is full of poisonous creatures. Some butterflies, beetles and frogs use bright colors to warn birds and other predators that they’re full of toxins. But you might be surprised to learn that some birds are poisonous, too. Birds called Hooded Pitohuis carry toxins produced by a beetle that they eat, Ruffed Grouse can pick up a poison from a plant called mountain laurel, and Common Quail so...

Some of the largest populations of Tufted Puffins are in the Aleutian Islands of Alaska and other northern coastlines. But University of Puget Sound professor Peter Hodum says the smaller colonies that breed off the coast of Washington and Oregon could provide key insights to conserve the whole species. The challenges facing birds at the fringes of their range could be the same ones that will affe...

Weighing about as much as four paperclips, Bushtits are smaller than many hummingbirds. And they take full advantage of their diminutive size. While larger insect-eaters forage on the upper surfaces of leaves, Bushtits hang beneath them, plucking all the tiny insects and spiders hiding out of sight. They pair off to nest. (This male Bushtit is working on his nest.) Where they live in Western subur...

Imagine an Ostrich, an Emu, a roadrunner, and the world’s fastest man and woman, all lined up for a race. Olympic sprinter Usain Bolt holds the men’s record for the 100-meter dash — 28 mph — and Florence Griffith-Joyner ran it just a shade slower. But in this race, Africa’s Ostrich takes gold, crossing the finish line at an incredible 43 mph. The Emu from Australia takes silver, topping 30 mph. Th...

A captive breeding program has helped set California Condors on the path to recovery. But when biologists reviewed the family tree for the breeding program, they found a big surprise. Two chicks had DNA that linked them perfectly to their mothers but didn’t match a single male. They arose through parthenogenesis, developing from unfertilized eggs without sperm from a male. These condors are the fi...

The sight and sound of the Bare-throated Bellbird—the national bird of Paraguay—inspires wonder and delight. Its presence as an indicator species and seed disperser also bodes well for ecosystem health in the Alto Paraná Atlantic Forests that stretch from Southeast Brazil through eastern Paraguay and into Northern Argentina. The loud, metallic call of the Bare-throated Bellbird also inspires music...

When biologist Danielle Whittaker started studying bird odors, some scientists tried to discourage her, claiming that birds can’t smell. But that only deepened her curiosity. Once, she caught a whiff of a cowbird, which smelled to her like sugar cookies. Danielle and her colleagues studied Dark-eyed Juncos and found that they produce many odors that help influence breeding behavior. Learn more in...

The Black-billed Magpie is a familiar sight throughout much of the west. The magpie's bulky nest is a rough sphere of sticks nearly three feet across, with entrance ports on the sides. Take a field trip with your local Audubon and see what you can see! More info and transcript at BirdNote.org .  Want more BirdNote? Subscribe to our weekly newsletter.

Shortly after the Russian invasion of Ukraine in February of 2022, zookeepers at the Kyiv Zoo shared audio recordings from the animal enclosures with BirdNote. The Zoo staff maintained care for the animals even as they slept in bomb shelters. Two and a half years later, Zoo Program Manager Olga Baratynska shares new audio of animals at the zoo and a report on their animal therapy program, called “...

Kingbirds are robin-sized flycatchers that excel at plucking insects from the air. They’ll even tackle prey as big as cicadas. Finding naturally-camouflaged cicadas hidden among the leaves is hard work. But two species of kingbirds in Arizona found a shortcut — stealing them from cicada-killer wasps! The female wasps, nearly two inches long, paralyze cicadas and bring them to their burrows for the...

The glorious song of the male Sage Thrasher rings out every Spring from tracts of sagebrush throughout the west. Sagebrush was once widespread in the Great Basin region, and so were the thrashers. But huge areas of sagebrush were turned into alfalfa and potato farms, and the songs of the thrasher aren't so common today. Sagebrush badly needs advocacy. The Important Bird Areas program works to prot...

House Finches are familiar birds all across North America. Researchers have shown that the red coloration of males is produced from carotenoid pigments in the birds' diet. Male House Finches develop brighter plumage when they are growing in new feathers, if they eat more fruits containing carotenoids. Females prefer more brightly colored males. Redder males also attract females in better condition...
