To find out if a crow can recognize an individual human face, Professor John Marzluff of the University of Washington wore a mask while trapping, banding, and then releasing seven American Crows on campus. Later, when he walked through the campus wearing the mask, it was automatic! A big group of birds scolded and divebombed him. He thinks it's a benefit to the birds' survival to point out and rec...

A blip on weather radar might not be a cloud — it could be thousands of birds! Biologists use radar to keep track of migratory birds, insects, and bats. An online resource called BirdCast combines decades of biological research, citizen science observations, and radar data to forecast the movements of migratory birds. You can use these predictions to help plan a birding trip. More info and transcr...

Hooded Mergansers, affectionately known as “Hoodies,” nest across most of the northern US and well into Canada. They’re especially prevalent around the Great Lakes, though some winter as far south as Florida. By November, courtship and pair formation is well under way. And by early spring, Hoodies will seek out secluded woodland ponds, where they nest in tree cavities or manmade nestboxes. Hooded...

In this episode, ornithologist J. Drew Lanham reads a letter he has written to a wood-pewee, a flycatcher with an “understatedly simple and definitive” song that says the bird’s name.

After hawks and eagles, some of the sharpest eyes belong to hawk-watchers, experienced spotters who count raptors during spring and fall migration. Groups like HawkWatch International organize census counts of hawks (like this Red-tailed Hawk) and other raptors. HawkWatch sites lie along primary migration routes like mountain ridges and coastlines, where updrafts of rising air funnel the birds’ no...

The song of the Black-capped Chickadee pretty much the same throughout the U.S. and Canada — with just a few exceptions, like on some Massachusetts islands. Chickadees on Martha’s Vineyard and tiny Tuckernuck Island nearby have developed songs entirely their own. It’s likely that the birds’ isolation from mainland birds led them to develop unique behaviors. More info and transcript at BirdNote.org...

Monk Parakeets, also known as Argentine Parrots, are native to South America but have become popular as pets – thanks in part to their intelligence and ability to mimic human speech. But in some areas, such as Mexico, these birds have become invasive. After being released or escaping, some Monk Parakeets have formed feral populations that have quickly spread, competing with native bird species for...

Millicent Ficken spent her career studying bird behavior and communication. The first woman to earn a PhD in Ecology and Evolutionary Biology from Cornell in 1960, Ficken authored over 100 scientific papers. She discovered that male hummingbirds have a whole repertoire of songs rather than just one, outlined the linguistic differences between penguin species, and showed that chickadees take turns...

Chickadees and titmice, nuthatches and jays, and woodpeckers, like the Pileated pictured here, all love suet. As do birds whose beaks can’t open seeds, like tiny kinglets, and almost any wintering warbler. The Brown Creeper, usually creeping up tree trunks, is a cool bird to discover at your suet feeder. And in the West, look for mobs of tiny Bushtits, taking a break from their normal diet of inse...

Many Brown-headed Nuthatches make their home in the tall longleaf pines of the Apalachicola National Forest in Florida. Twittering constantly, the birds probe for tiny insects or extract seeds from cones in the trees’ upper branches. Forests of longleaf pine once dominated the sandy coastal plain from Virginia to Texas, but the tall, straight pines proved irresistible for their lumber. Now, much o...

Waved Albatrosses produce such slow-growing, needy offspring that females lay only a single egg every two years. And both parents need to share the load until youngsters can hunt on their own. Albatrosses tend to pair for life, and reunited pairs go through an elaborate, synchronized ritual of braying, wing spreading, and bill tapping to reaffirm their bonds.

Mair Marsiglio is an avid birder, and they are also a psychologist with a background in trauma therapy. A few years ago Dr. Marsiglio worked with the San Francisco Bay Bird Observatory to facilitate mindfulness birding walks for veterans in a trauma treatment program. The walks helped participants ground themselves and provide a sense of connection. More info and transcript at BirdNote.org .  Want...

Found in Southern Mexico and Central America, Resplendent Quetzals have a striking blue tail up to three times the length of their bodies. That's probably why the Aztecs considered this bird a representation of Quetzalcoatl, the feathered serpent, one of the most worshiped gods across ancient Mesoamerica. But no matter how sacred, Resplendent Quetzals are currently considered near threatened due t...

The songs of two common finches provide a steady soundtrack in cities across North America: the House Finch and the American Goldfinch. While they can sound similar, a couple of key features help set them apart. House Finches sing sweetly but often have a sharp, buzzy note near the end. Goldfinches sing rapidly, often repeating a note several times. They also often make their distinctive call, whi...

American Robins (like this male seen here with its young), House Finches, and Song Sparrows may all nest within one small garden. By selecting different nesting strata, the species avoid competing for the same nesting sites. If you plant your garden in multiple layers – trees both short and tall, shrubs, and ground-hugging thickets – you may be rewarded with a multi-layered medley of bird song. Mo...

Desert raptors get most of their water from eating prey animals. Biologist Blair Wolf explains, “if you think of any insect or a mouse or something like that, they’re maybe 75% water.” Those animals become less plentiful in a hotter, drier climate. Extreme warming poses a direct danger to the raptors (such as this Harris's Hawk) and leads to lower rates of reproduction. Lacking sufficient water, t...

For years, biologists have been seeing migratory birds arriving earlier in the spring due to the effects of climate change. But surprisingly, the effect on arrival time is different for members of the same species. Male birds are changing their arrival dates faster than females in many species of birds that breed in North America. While it’s still unclear what effect this has on bird populations,...

The American Dipper stands on a rock in a stream, bobbing up and down on its long legs - "dipping" - hence the name. But watch! This nondescript bird steps off a small boulder right into the torrent, and begins to peer under water. What the American Dipper might lack in bright color it more than surpasses with amazing aquatic abilities. You can learn more about river restoration and protection at...

We make it a habit to detail the broad and beautiful spectrum of bird colors, but iridescent feathers are undoubtedly among the most mesmerizing. When sunlight hits the Bufflehead’s dark head feathers at the right angle, their colors transform into shades of the rainbow, from deep violet to green and gold. Common Grackles, caught in natural light, gleam gold, green and blue-purple. Starlings, too....

A pair of Bald Eagles will reuse their nest each year and repair it with new tree branches. But recently in British Columbia, scientists came across an eagle nest made largely out of dried kelp. Back in the ‘90s, that very nest had been made out of tree branches. What changed? Sea Otters were reintroduced to the landscape, which helped kelp forests flourish — and occasionally wind up in an eagle’s...

In spring, we often hear woodpeckers hard at work, carving out nest holes in tree trunks. And now that fall has arrived, we may hear that excavating sound again. Some woodpecker species stay year round in the region where they nest, while others migrate south in winter. Those that remain, like this Pileated Woodpecker, are chiseling out roosting cavities, snug hollows where they’ll shelter during...

This Bar-tailed Godwit makes one of the longest migrations of any animal — a 7,200-mile non-stop flight each autumn from western Alaska to New Zealand. In his book A World on the Wing , Scott Weidensaul explores the remarkable transformation godwits undergo to make this migration possible. Their digestive organs shrink as their weight more than doubles in stored fats and muscle mass. More info and...

As most young male birds get ready to leave the nest, they learn their species’ song by hearing their male parent sing it again and again. They imprint on their father’s song. So how does a Brown-headed Cowbird, raised by parents of a different species, learn to sing the correct song? The “chatter call” of an adult cowbird triggers something in the young bird’s brain. Like a kind of “password,” th...
