Japanese researchers said Monday they had developed a "hummingbird robot" that can flutter around freely in mid-air with rapid wing movements.
A newly constructed family tree of the hummingbirds, published today in the journal Current Biology, tells a story of a unique group of birds that originated in Europe, passed through Asia and North America, and ultimately ...
Hummingbirds rank among the world's largest and most accomplished hovering animals, but how do they manage it in gusty winds?

The twirling seeds of maple trees spin like miniature helicopters as they fall to the ground. Because the seeds descend slowly as they swirl, they can be carried aloft by the wind and dispersed over great distances. Just ...
Each year, a new bird is found and every four years a new mammal discovered in the Peruvian Amazon, a haven for biodiversity where conservation and danger often go hand in hand.
