Gentoo Penguins live in the frigid waters of the Atlantic. Only recently have scientists begun to unravel why penguin feathers don’t freeze. An electron microscope revealed tiny pores on the feathers that trap air, making the surface water repellent. This feature, plus a special coating oil from the preen gland, prevents water build-up and delays freezing. Engineers could attempt to apply these principles to prevent icing on plane wings.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Driving down a country road in eastern Ontario, there’s a surprising sight by the roadside: dozens of vibrantly coloured, eclectic birdhouses sitting atop 12-foot poles. It’s called Birdhouse City, and it’s in a conservation area boasting close to 100 birdhouses, with 30 under renovation. The initial birdhouse designs were based on nearby historical buildings, from the general store to the courthouse. About a third of them are occupied, with several species reliably taking up residence.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

When Juan Pablo Culasso spends time outside, he often encounters people thinking he doesn’t belong out there as a blind person – despite the fact that he’s a renowned nature recordist. He helped design nature trails in Colombia with features that make them more accessible for people who are visually impaired, including guide ropes with textures that signal points of interest and QR codes that provide info. But Juan Pablo says these are not simply trails solely for blind people to enjoy — “we need to share the same places in society,” he says.More info and transcript at BirdNote.org. Want more BirdNote?

Trumpeter Swans land in a plowed field to forage for remnant potatoes, grain, and other waste crops. This swan is among the largest of all waterfowl; the Tundra Swan is somewhat smaller. These swans migrate in family groups each fall from nesting sites in Canada and Alaska. Learn more about these swans, and view a map to the Skagit Flats of Washington where you can see them. When you go, please be courteous, and if you stop, pull completely off the roadway. Always respect private property.

The Cuban Giant Owl, now extinct, was 3½ feet tall and weighed 20 pounds — the largest of all known owls. It had very small wings, running after its prey on long, powerful legs. Similar large owls, with long legs and small wings, have been unearthed in places as disparate as Georgia and Hawaii. Very little is known about why giant owls died out.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Esha Munshi co-founded the Feather Library, a digital library that collects and documents the feathers of Indian birds. Launched in 2021, the library has high-resolution photographs of about 90 bird species. This library is open to everyone — whether you’re a researcher, birdwatcher, conservationist, or an ordinary person who came across a feather.More info and transcript at BirdNote.org. Want more BirdNote?

Pigeons — and other birds with eyes on the sides of their heads — have a different view of the world from that of creatures with forward-facing eyes. The images from a pigeon’s eyes overlap slightly, so the bird can see in front of itself, even though it has worse depth perception. But these laterally placed eyes have a big advantage for prey species: they provide a much wider view of the world. A pigeon has a remarkable 340º view without moving its head, including a wide area behind its head!More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

The tiny Common Redpoll, one of the smallest members of the finch family, weighs only as much as four pennies, yet it survives the cold and darkness of winter in the far North. Most birds depart in autumn to warmer climes. But redpolls feed on birch and alder seeds that are available throughout the winter, no matter how deep the snow. This little bird typically eats 40% of its body weight in seeds every day to keep itself alive. Redpolls are survivors.More info and transcript at BirdNote.org. Want more BirdNote?

In temperate climates like North America, it’s often male songbirds that sing the most. Typically the males migrate north before females and establish territories for the short breeding season, using their songs as a way to claim a spot. But many female birds do sing, even in colder climates. And in warm tropic zones, female birds often have a big role in defending a territory, and many of them sing just as loudly and artfully as the males. More info and transcript at BirdNote.org. Want more BirdNote?

Birds like male turkeys or barnyard roosters have a wrinkly, bumpy flap of red skin called a wattle. But what are wattles for? Birds can’t sweat, so wattles help release excess heat. Wattles are also key to courtship displays. Many other birds, including some storks and plovers, also have wattles.More info and transcript at BirdNote.org. Want more BirdNote?

Many jays, including this California Scrub-Jay, store food for sustenance in harsher seasons. An individual bird may cache nuts, insects, and even worms in several thousand spots. If jays visit your yard, here’s a game you can play with them. Each day, preferably when the jays aren’t watching, place a dozen peanuts in different parts of the yard. They should be visible, but scattered. When a jay arrives, watch how long it takes to find the nuts. The next day, place the nuts in a different array and watch again. Do the jays find them quickly? They might already have a mental map of everything in the yard, so anything new — like a peanut in a novel spot — seems to jump out at them.More info and transcript at BirdNote.org. Want more BirdNote?

Red Warblers only sing on sunny mornings during the breeding season — so hearing their song is as good as checking the weather forecast. Weighing less than a triple A battery, Red Warblers are endemic to the highlands of Mexico and live in humid forests of pine, oak, and fir. More info and transcript at BirdNote.org. Want more BirdNote?

A fine woodworker has a chest full of tools, each designed for a specific task. Birds also have highly refined tools-their bills. The size and shape of a bird's bill match perfectly the food they seek and the way in which they obtain their meals. Different species of shorebirds that forage shoulder to shoulder in tidal estuaries (like this Marbled Godwit and Willet) have bills of different lengths. As a result they don't compete for the same food. More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

The Red-backed Fairy-Wren, a tiny songbird living the Australian scrublands, is highly territorial and promiscuous. The male can’t be sure the eggs in his nest are his own. One way to help avoid this problem? The male may rough up a rival who approaches his territory. But research shows when Red-backed Fairy-Wren pairs sing a duet in order to deter rival males from intruding on their territory, those pairs had more of their own genetic offspring in their nests. For the male, aggression might not ensure paternity, but singing a duet could.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

If a young American Robin survives its first winter, its chances of survival go up. But robins still don’t live very long. The oldest robins in your yard might be about three years old (although thanks to banding, we know of one bird that lived to be almost 14).More info and transcript at BirdNote.org. Want more BirdNote?

When BirdNote’s Executive Director Nick Bayard joined BirdNote, he knew it would involve sharing the joy and wonder of birds with our listeners, but he didn’t expect it to inspire his kids to become avid birders. Now, his children Piper and Keaton are the ones asking to go on bird walks! In this show, Piper and Keaton share their favorite birds. More info and transcript at BirdNote.org. Want more BirdNote?

Songbirds in winter flocks benefit from having other birds nearby. They can recognize warning signals from other species and follow them to sources of food. We think of BirdNote’s audience as our flock, and we’re much stronger together than as individuals. But every single member of the flock counts, and every action is important. Support from our listeners is what keeps BirdNote in the air and on the air. BirdNote is an independent nonprofit organization that relies on support from listeners like you. This week, we are asking you to keep us flying strong by making a donation now.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.
