When a Northern Saw-whet Owl spreads its wings, many birds can see something our human eyes can’t: the owl’s flight feathers glow with ultraviolet light. It’s invisible to humans without the help of a UV blacklight. While the glowing feathers on parrots might help them attract mates, the reason for the owls’ glowing feathers still isn’t clear. However, scientists realized that they could estimate an owl’s age based on the pattern of luminescent color on the wings, which changes predictably as bi...

Compared to many birds, Great Horned Owls remain with their parents a long time. They hatched in early March, from eggs laid in late January. By April, both parents were hunting through the night to feed their young. But for the last two weeks, the adults have not fed the young. The owlets have learned the skills they need to hunt for themselves. And any night now, the young owls will strike out on their own. More info and transcript at BirdNote.org . Want more BirdNote?

Novelist Kira Jane Buxton has written several books about a pet crow navigating a post-apocalyptic world. But her writing is full of real-world bird behaviors. She has taken inspiration from how sparrows line their nests with cigarette stubs — which can deter mites — and many other bits of animal trivia. “I maintain that anything I took liberties with, in terms of the more fantasy or fantastical elements of the novel, they're not half as exciting as what's really happening in nature,” she says. ...

Superb Fairy-wrens teach their embryonic chicks a secret code. This incubation call contains a special note that will later serve as a password. When the chicks have hatched, this password enables the adult birds to identify their babies in the darkness of their domed nest. A species of Australian cuckoo lays its eggs in the wren’s nest, hoping to pawn off the task of parenting. But wren chicks learn their mother’s song and incorporate the password note into their begging calls. More info and tr...

In Lafayette Park in St. Louis, Missouri, a dozen or so Eurasian Tree Sparrows from Germany were released. But unlike other introduced species such as the similar-looking House Sparrow, they did not spread very far and remained in a limited area in the Midwest. It’s not fully clear why, but it’s possible that they just behave differently. And the aggressive House Sparrow may have helped prevent the tree sparrows from spreading further by competing for the same nesting sites. More info and transc...

Birds called prions have an especially creative approach to getting their food. They pass seawater through their mouths and filter it to catch tiny animals such as krill and other small crustaceans. It’s similar to how baleen whales feed, leading to the prion’s nickname: the whale-bird. The sides of their bills have comb-like structures. Small food items get trapped in the combs as water flows past. In Greek, the word “prion” means saw, which refers to the bird’s highly specialized mouth. More i...

In addition to their scientific names, birds are also given "official" English names. Take the bird commonly known as the rain crow, for example, officially referred to as the Yellow-billed Cuckoo by the American Ornithological Society. Its scientific name is Coccyzus americanus. Of course, the bird doesn’t care what you call it, so long as it has plenty of hairy caterpillars to snack on. More info and transcript at BirdNote.org . Want more BirdNote?

During migration, some birds change orientation, often by a full 180 degrees, and travel almost the same distance — but in the opposite direction — as the rest of their species. The phenomenon is called misorientation. First-year birds are particularly susceptible. Many vagrant birds never find their way back on course, but some do, getting more comfortable with the route each year. More info and transcript at BirdNote.org . Want more BirdNote?

Once nesting season ends, swallows know it's time to party! Whether they nest as single pairs or in large colonies, both adults and juveniles now gather on electrical wires by the dozens, socializing before they migrate. Migrating by day – and foraging for insects as they go – swallows (including this Violet-green Swallow) head south to Mexico and Central and South America. More info and transcript at BirdNote.org .

The White-vented Storm-Petrel is a small black and white seabird found off the coasts of Chile and Peru. Storm-petrels spend their entire lives at sea, except when nesting. Scientists had long been mystified about just where this species nests. A search lasting eight years led them to a site 50 miles inland in the Atacama desert, a place often compared to the surface of Mars. They employed dogs specially trained to sniff out seabirds. The dogs helped locate White-vented Storm-Petrel nests tucked...

Brown-headed Cowbirds have a sneaky approach to parenthood. They lay eggs in the nests of other songbirds, and the songbird hosts often raise the cowbird chick as their own. It’s called nest parasitism. But sometimes the hosts throw out the odd-looking egg. And when that happens, the cowbirds sometimes retaliate by destroying the hosts’ other eggs. Scientists call this “mafia behavior,” likening it to organized crime groups enforcing their demands on unwilling business partners. More info and tr...

Keas are large alpine parrots from New Zealand. Intelligent and social, they have olive-green plumage, a red rump, and a long, curved beak. Keas produce a distinct warbling call, a “play call,” that sounds — and functions — much like a human’s contagious laughter. Scientists made recordings of captive Keas making warbling calls, then played them for wild Keas. They began playing harder and even engaged birds that hadn’t been playing. Hearing it seemed to put them in a playful mood, even when the...

In the late 19th and early 20th centuries, the human fascination with bird feathers went a little too far. Women’s hats and dresses featured extravagant feathers from birds both near and far. The trade in feathers drove several species, from the Little Egret to the Great Crested Grebe, to near-extinction. Fed up with the killing of wild birds for fashion, a group of British women met to put an end to this cruelty. The organization became the Royal Society for the Protection of Birds, or RSPB, wh...

Hummingbirds use their long tongues to sip nectar from flowers. They’re able to roll their tongues into a tube-like shape. Since the 1800s, scientists thought those tongues worked through capillary action, like how water instantly rises into a straw in a full cup. But when scientists spent years using slow-motion cameras to capture hummingbirds drinking in greater detail, they uncovered a completely different story: the tongues act like a tiny but powerful pump.

Sculptor and musician Walter Kitundu first became enraptured by birds in 2005 when a Red-tailed Hawk flew four feet above his head. He named the bird Patch, after the white patch on the back of her head, and kept returning to the park to see her. Patch became used to Walter, accepting him as part of the landscape. He documented her transition from juvenile to adult, learning her quirks and mannerisms. More info and transcript at BirdNote.org . Want more BirdNote? Subscribe to our weekly newslett...

Birds are part of the complex web of Nature, and each fits into this web in its own way. Some even pollinate flowers! While feeding at a flower, this Rainbow Lorikeet gets pollen on its forehead and throat. When it visits another flower of the same species, it transfers the pollen to that flower. The pollen fertilizes the plant's eggs to produce its seeds, and the plant's reproduction is assured. More info and transcript at BirdNote.org . Want more BirdNote?

Once abundant around San Francisco Bay, the Ridgway’s Rail — formerly known as the California Clapper Rail — is now endangered. In the 19th Century, unregulated hunting plundered the species. In the 20th Century, rampant development reduced salt marsh habitat by 85%. But in the 21st Century, the Ridgway’s Rail has allies. Restoration is under way to increase healthy saltmarsh habitat for these endangered birds. Also, efforts to control the number of predatory cats are improving the chances for t...

With their excellent sense of smell, pigs are renowned for sniffing out truffles, a fungus that grows underground and is prized for its taste. But it turns out that some bird species can also find their way to a truffle treat. Researchers working in the Patagonia region of Chile had noticed truffles with little beak-sized bite marks, and even watched a bird eat a truffle. They found truffle DNA in the birds’ droppings, suggesting that truffles are a staple of the birds’ diet. Some of the fungi s...

Let’s talk about nests. Every spring, robins build their cup-shaped nests using grass and mud. Orioles weave a hanging sack. It’s hard work, and yet once the chicks fledge, the structures probably won’t be reused. But bigger birds, such as herons, hawks, and eagles, often reuse a nest for many years. Europe’s migratory White Storks — like those pictured here — get the award for best reuse. One nest site, still used in 1930 and likely seeing many repairs, dated back to 1549. That’s a continuous s...

The American Crow’s rattle call is uncommon, and researchers aren’t sure what it means. It could be a gathering call, a predator alarm, or a call between mates. But if you hear it, you might think it sounds like cackling laughter. However, no one has identified a crow noise that indicates glee at the expense of another creature. It’s just a coincidence that the rattle sounds like a laugh. However, crows can play pranks on other animals: egging on cats to fight and yanking on dog tails for their ...

How does a robin know a worm is in one exact spot? Does it see the worm or hear it? Smell it? Sense its movements through its feet? To find the answer, researchers buried worms in soil in a tray. They covered the soil with a thin but opaque sheet of cardboard, followed by more soil, so the robin couldn’t see the worms. Still, the robin found them with ease. The scientists concluded the birds are listening for their prey. There’s always more to learn about birds! More info and transcript at BirdN...
