(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 ...

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 ...

(CN) — Engineers from an international research team have developed a new high-tech drone capable of mimicking the calculated yet erratic flying patterns of the swift, one of the most high-speed and ...

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.

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 ...

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 ...
