Glowing Feathers

BirdNote Daily ·

2024/09/30

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 birds

Great Horned Owl Family in Autumn

BirdNote Daily ·

2024/09/29

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?

The United States is home to more than 550 National Wildlife Refuges – havens for wildlife, including the Canvasback.

Bird Facts Stranger Than Fiction

BirdNote Daily ·

2024/09/27

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.More

Fairy-Wrens Sing Secret Passwords to Unborn Chicks

BirdNote Daily ·

2024/09/26

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

The Eurasian Tree Sparrow

BirdNote Daily ·

2024/09/25

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 transcript

In a clearing where an ancient Mayan city once stood, the Montezuma Oropendola perches and sings.

Prions Filter-Feed Like Whales

BirdNote Daily ·

2024/09/21

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 info

Yellow-Billed Cuckoo or Rain Crow?

BirdNote Daily ·

2024/09/20

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?

Migrations: You're Going the Wrong Way!

BirdNote Daily ·

2024/09/18

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?

Swallows on Wires

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.

Seabirds in the Desert

2024/09/15

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

Cowbird Mafia

BirdNote Daily ·

2024/09/14

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

Playful Keas

BirdNote Daily ·

2024/09/13

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 they

The Women Who Fought the Feather Fad

BirdNote Daily ·

2024/09/12

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, which

The Surprising Secret of Hummingbird Tongues

BirdNote Daily ·

2024/09/11

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.More info and transcript at
