A newly discovered feathered dinosaur fossil in China, named Jianchangmaensis, reveals a previously unknown species of ...

A fossil found in what’s now northwestern China belonged to a microraptor, a gliding dinosaur that hunted ancient birds.

A dinosaur cousin of the velociraptor may have glided through ancient forests on four wings to hunt early birds, scientists ...

New fossil reveals a bird-hunting, four-winged microraptor that expands scientists' understanding of dinosaur flight ...

An air-filled sac within the birds' lungs is believed to increase the force the birds use to power flight muscles while soaring. Soaring birds -- like osprey, eagles, falcons, even vultures -- can ...

A frigate in flight. Some of the juveniles in the study stayed continuously aloft for more than two months. How do frigate birds—seabirds with a 7-foot wingspan—stay aloft for months at a time? Their ...

While it had been assumed that unstable gliding was the key to agility in bird flight, a collaboration between aerospace engineers and biologists has revealed that stability plays a role. While it had ...

Engineers are finding new ways to make wind turbines more efficient by stealing design cues from one of the world’s heaviest aerial birds, the Andean condor. This is according to new research ...

Soaring birds — like osprey, eagles, falcons, even vultures — can stay aloft in the air seemingly forever, rarely flapping their wings. They glide along rising air currents in a way that has ...
