Music producer So Wylie began transforming bird calls and songs into musical “bird beats” during the pandemic. The first bird beat she made was inspired by Rocky, a Northern Saw-whet Owl that was found bundled up in the Rockefeller Center Christmas tree in 2020. Since then, the Boreal Owl, Barn Owl and Eastern Screech-Owl have been featured in her upbeat tunes. Learn more at BirdNote.org.

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. Learn more at BirdNote.org.

The Common Murre is among the few species of birds that can "fly" under water. When above the water, the 18"-long murre must flap frantically to stay aloft. But beneath the waves, with its flipper-like wings partly extended, it is a streamlined, masterful swimmer. Common Murres, black and white torpedoes with feathers, chase down fish even several hundred feet below the surface. Cornell's Macaulay Library offers audio and video of Common Murres.

A blip on weather radar might not be a cloud — it could be thousands of birds! Biologists use radar to keep track of migratory birds, insects, and bats. An online resource called BirdCast combines decades of biological research, citizen science observations, and radar data to forecast the movements of migratory birds. You can use these predictions to help plan a birding trip. Learn more at BirdNote.org.

Collective nouns are a mixture of poetry, alliteration, and description. Victorians often made up creative names for groups of birds, as a parlor game. Many names bring a vision of the birds instantly to mind. How about this spring of teal? These are Green-winged Teal.

So what would a bunch of BirdNote listeners be called? A gaggle? A flock? A watch? Learn more at BirdNote.org.

No bird is better adapted for climbing up a tree trunk than a woodpecker. The foot of this Pileated Woodpecker is ideal for clinging, and its relatively short legs allow it to anchor itself securely. When traveling upward, the woodpecker’s a master. But hitching down? Not so much — usually they will fly. Nuthatches, however, can easily go up and down. This White-breasted Nuthatch walks over the bark of trees by grasping with one leg while using the other for a prop. It also has a rear-facing toe equipped with a long, sharp claw that’s ideal for hanging on while heading downward. Learn more at BirdNote.org.

On Block Island, 11 square miles of land off the coast of Rhode Island, Kim Gaffett catches birds and puts metal bands on their legs to track them. This has helped reveal how the birds use their island layovers. Having crossed the ocean without eating or drinking, birds need stopover sites like Block Island to eat and refuel for the rest of their journey.Hear more about how Block Island helps migrating birds on the Threatened podcast.

The Common Merganser is one of our biggest ducks, about the size of some loons. Although it’s not closely related to loons, it has evolved a similar overall structure and predatory behavior. But a merganser has a unique feature: tooth-like serrations along the edge of the bill that help the bird grasp slippery fish. Common Mergansers nest in the northern states and Canada. So do loons. But loons nest on the ground at the edge of a lake, while the mergansers nest mostly in tree cavities and rock crevices near large lakes or along rivers. Learn more at BirdNote.org.

Tim Arnold leads the Tybee Clean Beach Volunteers in keeping Tybee Island, Georgia, free of plastic pollution and other trash. His favorite bird is the Brown Pelican. Its bulky, awkward appearance contrasts with its agility as it dives for fish. But Arnold worries that pelicans are ingesting microplastics as they feed. On Bring Birds Back podcast, host Tenijah Hamilton explores what we can do to protect birds from plastics.

One of the easiest ways to keep a finger on the pulse of the seasons is to keep an eye on the birds. When do the Dark-eyed Juncos (like this one) return from the mountains, ready to pick up at the birdfeeder where they left off last year? When do migratory Canada Geese fly over on an autumn evening? Keeping a simple diary of the seasons can be gratifying and bring you in touch with the annual ebb and flow of nature just outside your window. Learn more at BirdNote.org.
