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.

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…

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…

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…

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…

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…

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…

In Lafayette Park in St. Louis, Missouri, a dozen or so Eurasian Tree Sparrows from Germany were released. But unlike other introduced species such as the similar-looking House Sparrow, they did not spread very far and remained in a limited area in the Midwest. It’s not fully clear why…

Birds called prions have an especially creative approach to getting their food. They pass seawater through their mouths and filter it to catch tiny animals such as krill and other small crustaceans. It’s similar to how baleen whales feed, leading to the prion’s nickname: the whale-bird…
