Sailors once believed Wilson’s Storm-Petrels foretold a dangerous tempest. There might be a grain of truth: the tiny seabirds might find a little shelter from the gusts near a ship. Wilson’s Storm-Petrels are found in every ocean. When foraging, their feet patter across the surface…

Eared Grebes eat brine shrimp and aquatic insects for sustenance, but rigid exoskeletons make them hard to digest. So these grebes – along with their other grebe cousins – evolved to use their feathers as a way to slow down digestion. The feathers form dense balls in the digestive tract…

Like the American Robin, the European Robin is a bird of yards and gardens. But it’s not much bigger than a chickadee. The robin’s likeness turns up everywhere from Mother Goose rhymes, Peter Rabbit stories, and whiskey labels to postage stamps and Christmas cards. On at least two…

Snow Geese nest from far northeastern Russia to Greenland, in the arctic and subarctic. They winter in large flocks on the deltas of rivers in northwestern Washington, areas along the Eastern Seaboard, and throughout the Mississippi Flyway. Watching Snow Geese in flight, author and…

The Eurasian Hoopoe isn’t picky about where it nests. But whether it builds a home in a tree cavity, termite mound, or nest box, it’ll be stinky. Mother birds coat their eggs in an antimicrobial secretion that smells like rotten eggs. Then, when the chicks are hatched, they paint the nest…

On this episode of BirdNoir, the Mayor of Bricksville calls the Private Eye with a bit of a problem. “Several dozen giant bird-punks loitering on top of City Hall!” The detective figures out the most likely reason why these birds have chosen the top of a building as their hangout, and…

For most birds, wings are for flying. But for Rock Pigeons, they’re also for clapping. When the pigeons erupt into flight, some may slap their wings together above their bodies in a “wing clap.” A male Rock Pigeon will also do this when courting. Short-eared Owls have evolved wing-clapping…

In North America, the European Starling has gained a bad reputation for competing with native bird species for nest cavities. But researchers in Ontario, Canada, were surprised to see three Hairy Woodpecker nestlings receiving care from both a female Hairy Woodpecker and a European…

Knowing when to hunker down and when to move on is a matter of survival for the Red-headed Woodpecker. This noisy bird spends its summers taking insects from the sky in flashy, acrobatic flight. But prey is harder to find in winter, and in most years the woodpeckers move south. A bumper…
