Like today’s swans, the extinct species Annakacygna hajimei and Annakacygna yoshiiensis were quite large. But unlike their modern relatives, these birds lived most of their lives out at sea, and their fossils reveal remarkable adaptations to this unusual lifestyle. This led the researchers who first

Both this Eastern Towhee and the Spotted Towhee of the West sport a black or dark brown hood and back. And when they fly, their tails flash white. When a hawk gives chase, the towhee's flashing tail-feathers draw the predator's attention. Momentarily distracted, the hawk may come up with just a

Roosters don’t need to set an alarm to tell them when it’s time to crow — their internal circadian clock lets them anticipate sunrise with remarkable accuracy. To us sleepy humans, it may seem like they all start crowing at once. But scientists have found that roosters follow a strict social

Hudsonian Godwits are tough birds to find, and they were once thought extinct due to overhunting. After nesting at sites scattered in the High Arctic, they migrate south on a route that takes them over the ocean from Canada to South America. In spring, they head north through the Great Plains

In August 2008, Kasatochi Island erupted in the middle of auklet breeding season, burying tens of thousands of chicks in hot ash. At first, the auklets’ future on the island appeared bleak. But in just a few years, the birds had returned in force. Thousands nested within the innumerable chambers
