A bird known as Titanis walleri made its home in Florida just a few million years ago. Titanis, as its name suggests, was titanic indeed — a flightless predator, 5 feet tall, with a massive hooked bill. Titanis and other birds related to it belong to a group some paleontologists call the…

To hear a Common Loon in the wild during summer, you’ll need to find a northern, freshwater lake where a pair is nesting. But to find that same Common Loon in winter, you’ll likely need to look on a saltwater bay. This shift from fresh to salt water would kill most animals. But loons —…

In the depths of winter, when open water is frozen over, it can be challenging for birds to stay hydrated. Some birds eat the frozen water all around them. Cedar Waxwings catch snowflakes in mid-air. Black-capped Chickadees drink from dripping icicles. Plenty of other birds scoop up fresh…

Named for its rhythmic calls, the Black-legged Kittiwake is a dapper, oceanic gull. As described by conservationist Roger Tory Peterson, the tips of its pale gray wings "are cut straight across, as if they had been dipped in ink." Unlike many gulls, kittiwakes spend most of the year at sea…

There are five million bird eggs stowed away in museums across the world — and the study of eggs, called oology, can give us great insight into birds. The link between DDT and the decline of Peregrine Falcon populations was identified in part using museum and personal egg collections, and…

Sometimes, a species’ song changes over the course of a few decades. But a bird that lives in the mountains of eastern Africa, the Forest Double-collared Sunbird, appears to have kept the same song for at least 500,000 years. That’s the amount of time that two populations of the species…

Every summer, puffins — like this Horned Puffin — grow blazingly colorful layers over the bases of their huge beaks. But in the winter, puffins lead very different lives, and they shed their bright ornamentation. Puffins in winter are largely solitary — and silent. They spend about seven…

Gyrfalcons are circumpolar, nesting in the far north of Asia, North America, and Europe, including Iceland and Greenland. They evolved as a distinct species in the Pleistocene Era, around 100,000 years ago. Their large size and warm feathering gave them an edge for nesting high in the…

It’s early morning in Costa Rica. Tiny bats nestle in a tree after a night on the wing. A Great Kiskadee calls. Gray-capped Flycatchers sally forth from willow-like shrubs to catch insects in mid-air. White Ibis forage at the water's edge. Deep in a thicket, Black-hooded Antshrikes call…
