At a glance, swallows and swifts, both graceful fliers, look much alike. But swifts — like this Chimney Swift — have longer, slimmer wings and short bodies, enabling them to glide for long periods. Their glides are punctuated by rapid, stiff bursts of wing-beats. Swallows, on the other hand, flex and flap their wings. Why do swifts have such a peculiar, stiff wing stroke? Picture a bird wing, with two halves jointed in the middle. Swift wings have a short inner “half” and a long outer half. This causes the stiffness. More info and transcript at BirdNote.org.

At the end of summer, the once-bright feathers of a male American Goldfinch look ragged. Growing new flight feathers in a process called molting makes him more vulnerable to predators. Before migrating to wintering grounds, many songbirds stop at a secondary location to undergo the awkward phase of feather replacement. It’s called molt migration. The places birds go to molt could be important targets for conservation efforts. More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

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 the Ridgway’s Rail to survive. More info and transcript at BirdNote.org. Want more BirdNote?

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 transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

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.

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 series of stork pairs nesting in one spot for 381 years! More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

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 were alone. More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.

In this episode, ornithologist J. Drew Lanham reads a letter he has written to an Olive-sided Flycatcher, a beloved bird that he pleads with to visit the dead pine tree on the edge of his home by a mountain lake.

In the summer of 2026, conservation photographer Gerrit Vyn visited a remote wilderness called the National Petroleum Reserve in Alaska. He spent much of June at Teshekpuk Lake, just 6 miles south of the Arctic Ocean. The vast wetlands in this region are critical for millions of birds that come from around the world to breed every year. In this episode, Gerrit shares the sights and sounds of three standout shorebirds: Dunlins, Semipalmated Sandpipers, and Pectoral Sandpipers. More info and transcript at BirdNote.org.

By early August, the rich yellow of the feathers of the Wilson's Warbler seems to flash in every forest thicket. Despite predators and weather, many pairs of adults have raised four young, which now flit about on their own. The young males hatched this spring learned their father's songs this summer. Next spring, they, too, will sing those songs. By buying shade-grown coffee, you can help preserve the wintering grounds of this bird and many others. Listen to this show in Spanish here.

In September, this Arctic Tern flies from Alaska all the way to Antarctica. Rufous Hummingbirds follow pathways of mountain wildflowers, from as far north as Alaska south to Mexico. Ruby-crowned Kinglets, migrate attitudinally from the mountains to the lowlands. Each of these birds migrates, but on a very different course. All make the most of food and breeding opportunities that change with the seasons. More info and transcript at BirdNote.org. Want more BirdNote? Subscribe to our weekly newsletter.
