Standing in a tropical forest at night, you might hear what sounds like a small bird calling from high in the canopy. Listen ...

New research has found that, unlike birds, the evolution of bats' wings and legs is tightly coupled, which may have prevented them from filling as many ecological niches as birds. New Cornell ...

Wing-beat-frequency data for a variety of flying animals versus the square-root of the animal mass divided by the wing/fin area. A single universal equation can closely approximate the frequency of ...

The dream of flying has always fascinated humanity. In evolutionary history, the ability to fly has emerged independently only three times: in birds, pterosaurs, and, uniquely among mammals, in bats.

To exploit a rich food resource that remains largely inaccessible to most predators, Europe’s largest bat captures, kills, and consumes nocturnally migrating birds in flight high above the ground, ...

One summer night three years ago, a chimney swift flitted over the Middle Creek Wildlife Management Area, where a scraggly-looking antenna sensed a radio frequency pulse given off by a transmitter no ...

A Black Skimmer uses its long wings to soar above the water. Every other Friday, the Outside/In team here at NHPR answers listener questions about the natural world. Today's question comes from ...

The Bats and the Bees The wording of your article1 was sufficiently imprecise to provoke a brain gag on my part. Bat and bird wings are homologous!? No! Analogous, I say. They do NOT use the same ...

Research teams studying bats and birds gather in Panama’s Soberanía National Park to celebrate the launch of a long-term census of bats designed to complement the bird census, which will celebrate its ...

Inspired by the remarkable flight capabilities of birds, bats, and insects, flapping-wing robotics represents one of the most promising frontiers in bio-inspired aerial systems, demonstrating enhanced ...

Birds, bats and bugs fly, but how? We take an in-depth look at the mechanics of flight. HERE’S THE THING: the humble locust can fly hundreds of kilometres without refuelling – 500km is not an unusual ...
