Birdnote

Willistown Conservation Trust in Pennsylvania carries out bird banding to help researchers understand bird populations. Led by licensed bird banders, a team of volunteers catches birds using mist nets — 8-foot tall nets made of fine nylon string that practically disappear when strung out between poles. After carefully untangling birds from the net, volunteers weigh and measure the birds, affixing a small metal band to their legs with a unique ID. Compiling records for many banded birds helps keep track of whole species.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Although we may think of autumn as the end of the growing season, a sort of winding down in the natural world, for birds it’s as much a season of renewal as the spring. In the colder months, we welcome back our winter birds — juncos, swans, and more — which spent the summer in their breeding territories to the north. Offering the right kind of food and environment in the winter months can attract these migrants to your yard!More info and transcript at BirdNote.org. Want more BirdNote?

When courting in spring, male and female Cedar Waxwings communicate with distinctly different calls and, perched side by side, often pass back and forth between them a berry or other small fruit or even a flower petal. Waxwings display a wealth of eye-catching plumage. If you relish the company of Cedar Waxwings, plant fruit-bearing trees and shrubs.

Despite their name, Prairie Warblers nest in tree farms of recently planted pines, in fields overgrown with scattered shrubs, and in clearings under power lines. Biologists call these “early successional” habitats. They’re characterized by plants that are the first to return to land altered by clearing or fire. Prairie Warblers and similar birds have declined rapidly during the last 50 years, being pressed from all sides. But they’re now benefiting from conservation on several fronts, including the Michael Huber Prairie Warbler Preserve in New Jersey’s Pine Barrens and the Albany Pine Bush Reserve in New York.More info and transcript at BirdNote.org. Want more BirdNote?

An online tool called BirdNET uses artificial intelligence to identify bird songs and calls. And Cornell’s well-known Merlin Bird ID app now has sound ID, too. It’s as simple as opening the app, choosing “Sound ID,” and hitting record. It can pick out multiple species in the same recording.More info and transcript at BirdNote.org. Want more BirdNote?

Sooty Terns have long been called "wide-awakes" because of their calls. But it may describe their sleeping habits, too. When young terns leave their breeding grounds, they don't return for several years. They do not rest on the water, and only rarely land on floating objects. They feed while aloft, grabbing prey from the ocean's surface. On the fly, they also capture fish that have been chased out of the water by predators. In other words, Sooty Terns live in the air for years at a time.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

During migration, Snow Geese gather in the tens of thousands. They coordinate their movements, flying in a big, compact flock, which makes it harder for a predator to pick off a single bird. It is truly something to see.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

Due to trapping for the pet trade, the talkative and showy Yellow-crested Cockatoo is now considered critically endangered. But scientists recently discovered a stronghold for the species: Komodo Island — yes, the one with the dragons. The Komodo population of Yellow-crested Cockatoos appears stable. The island has been an Indonesian national park since 1980. Park rangers may have helped deter poachers, but community support for conservation and the literal dragons have played a role, too.More info and transcript at BirdNote.org. Want more BirdNote?

Puffins fly under water into schools of slender fish, filling their large beaks. Fish are wedged into the gape, the stretchy skin at the beak hinge, but the bill edges still line up neatly. The dangling fish won’t slide out because the puffin’s tongue and roof of the mouth are heavily lined with backward-angled spines. When its beak is full, the adult flies back to its nest and feeds it all to a single chick.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

In autumn, hundreds of thousands of Swainson's Hawks migrate to South America.

Long, upward slopes called escarpments offer a good chance of seeing some of the many raptor species found in Belize. Shaped like a compact Red-tailed Hawk, White Hawks are white overall with black markings and scan the landscape for reptile prey. Bat Falcons have a darkly barred chest and cinnamon belly, and chase down swifts, dragonflies, and the bats that give them their name. Ornate Hawk-Eagles stand over two feet tall and are capable of catching monkeys.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

A female Wood Thrush will carefully choose each piece of nest-building materials because her eggs will depend on it for warmth and protection. But even the best-made nest couldn’t exist without the support of a sturdy shrub or tree. Much like a bird’s nest, BirdNote depends on having a solid foundation on which to build.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

The Purple Martin is the largest swallow that nests in the US and Canada. During fall, Purple Martins from western North America migrate to a distinct wintering area in southeastern Brazil — a travel distance of more than 5,000 miles! Scientists believe that Purple Martins started out as a South American swallow species. Over time, they evolved a seasonal migration to North America because the longer days of summer sunlight provided extra hunting and feeding opportunities during nesting season.Listen to this episode in Spanish here.More info and transcript at BirdNote.org. Want more BirdNote?

To figure out the source of a hummingbird’s hum, scientists built a special rig to measure air pressure, twelve high-speed cameras, and over 2,000 microphones to observe hummingbirds fluttering in place at an artificial flower. The researchers found that the hum derives from the difference in air pressure between the top and bottom of the wings, which alternates forty times a second as the hummingbird flaps. The rapidly shifting air pressure produces a harmonic set of sounds, from low to high, creating that iconic, musical hum.More info and transcript at BirdNote.org. Want more BirdNote?

Some migratory songbirds such as European Robins have special light-sensitive proteins called cryptochromes in their eyes. New research suggests how the cryptochromes could alter their behavior in the presence of magnetic fields, giving birds a visual cue for north and south. Other birds can navigate with the help of a mineral called magnetite in their beaks.More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.
