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.

Related to shearwaters and petrels, the Northern Fulmar will eat just about anything it finds on the surface of the ocean, from fish and squids to dead whales. While some have snow-white bodies and gray wings, others are dark gray all over. That’s because fulmars are polymorphic, which is to say they come in multiple colors or “morphs”. The difference is genetic and doesn’t depend on age, sex, or season. Thi...

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 ...

It’s a wistful moment when your backyard birds — like these Black-capped Chickadees — depart their nestboxes. By October, it’s time for one last duty as nestbox landlord: to clean it out. Cleaning will reduce the incidence of parasites in the box and make it more inviting to next spring’s tenants. It will also help you know for sure if it gets used again.

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 al...

Evolution works with what's at hand. So if you start with a normal bird skull – bill pointing forward, eyes oriented front or sideways, ears behind eyes – and introduce the challenge of seeing behind your head while your bill is pushed deeply into the soil, what do you get? The American Woodcock! With its long bill constantly probing the soil for earthworms, its entire skull has been rearranged. Relative to other birds,...

When Chidi Paige moved from Nigeria to the U.S., she began running a youth STEM program and had to teach lessons on bird identification. She was in for a challenge: she had to learn the local bird species quickly. On a birding trip, she spotted a Northern Yellow Warbler in a pine tree. The beautiful warbler got Chidi hooked on birding. She has designed several games to make learning bird identification fun for kids.

Gnatcatchers are tiny, black and gray songbirds native to the Americas. Though they don’t typically catch gnats on the wing, gnatcatchers are often found moving rapidly through the high canopy as they glean insects from leaves. There are four species found in the U.S. and Canada: Blue-gray Gnatcatchers, Black-tailed Gnatcatchers, Black-capped Gnatcatchers, and California Gnatcatchers. It takes time and effort to find them all...

Morning is a great time for birding – that’s the peak of singing and foraging activity for many species. But it’s not the only time to experience birds. Some species, such as American Robins, sing for much of the day. Daytime predators such as hawks and cormorants are active in the middle of the day. Some birds such as Common Nighthawks sweep the sky for insects at dusks. And many owls come awake at night!

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...

The crocodilians — crocodiles and their relatives, like the American Alligator — are the closest living relatives of birds. About 250 million years ago, the ancestors of all crocodiles split off from the dinosaur group that gave rise to modern birds. While crocs these days are mostly short-legged ambush predators, before mass extinction there were ocean-dwelling crocodilians and even species that ran around on two legs.

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 othe...

The Purple Martin is the largest swallow that nests in the U.S. 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...

Saturday October 10, 2026, is World Migratory Bird Day, a celebration of one of our planet’s most marvelous natural phenomena. It occurs twice a year, on the second Saturday of May and October, in observance of peak spring and fall migration in the Americas. This year’s theme is “Every Bird Counts,” which highlights the importance of community science to migratory bird conservation worldwide.

Smaller than a pigeon — but fierce enough to knock one from the air — are the powerful, compact falcons known as Merlins. Climate change is pushing ranges of many birds farther north, but more and more Merlins have been nesting farther south, in towns and cities across the northern United States. Merlins will take over old crow nests, especially in conifer trees, in parks, cemeteries, and neighborhoods.

This Bar-tailed Godwit makes one of the longest migrations of any animal — a 7,200-mile non-stop flight each autumn from western Alaska to New Zealand. In his book A World on the Wing, Scott Weidensaul explores the remarkable transformation godwits undergo to make this migration possible. Their digestive organs shrink as their weight more than doubles in stored fats and muscle mass.

 When you think of bird migrations, you might think of a bluebird or a robin first. But some owls do migrate – such as the Short-eared Owl, which flies south for the winter. Northern Saw-whet Owls were once thought non-migratory, but in fact they travel at night, unseen. Snowy Owls breed in the Arctic then wander toward the south, staying wherever they can find food. Some Burrowing Owls spend their whole life in one plac...

Biologists with Manomet tagged a Whimbrel named Lindsay with a GPS tracker. She has spent the summer breeding in the Arctic National Wildlife Refuge on the northern coast of Alaska. As fall migration begins, she heads straight into a storm in the Gulf of Alaska. The tempest slingshots her toward British Columbia, where she picks up a tailwind down the California coast. Landing near San Francisco, she rests and refuels.

In the October sunlight, a Lincoln's Sparrow – like this one – sings energetically from a hedgerow. Soon a Fox Sparrow chimes in. Both nested in Alaska last summer but will spend the winter farther south. The Snow Geese are moving, too. A massive movement of birds takes place in the fall. The exodus of summer visitors to the tropics has given way to a surge from the north. And predators can't be far behind.
