(CN) — Scientists have discovered two distinct subspecies of fork-tailed flycatchers that communicate with each other by producing a high-pitched frequency with their feathers — and exhibit regional ...

A new study into the flight characteristics of condors — the largest soaring birds on Earth — finds that they rarely flap their wings once airborne. Condors are capable of flying for over a hundred ...

Charles Darwin once posited that birds might flap their wings to communicate, not just to fly. However, this has always been pretty tricky to test. Now, 150 years later, researchers have discovered ...

NPR's Scott Detrow speaks with Matthew Medler of the Cornell Lab of Ornithology about the best bird sounds of 2025 from their vast collection of recordings, and why their selections made the list.

A drone prototype that mimics the aerobatic manoeuvres of one of the world's fastest birds, the swift, is being developed by an international team of engineers in the latest example of biologically ...

Andean condors, at 10kg or more, are among the world’s heaviest flying birds. Once birds get this big, the energetic costs of flapping are so high they instead rely on currents of rising air to travel ...
