Modern birds capable of flight all have a specialized wing structure called the propatagium without which they could not fly. The evolutionary origin of this structure has remained a mystery, but new ...

“Awkward” would probably be the most benevolent word I could use to describe the explosive launch into flight of the California quail. Certainly, the words graceful or athletic do not come to mind.

The Wright Brothers studied bird flight before they designed the first airplane. Now modern aircraft fly higher and faster than any bird, yet no manufactured device matches the graceful movements and ...

Scientists undertook a study of dragonfly wings in order to better understand the relationship between a corrugated wing structure and vortex motions. They discovered that corrugated wings exhibit ...

Hi-res X-ray movies reveal that despite having extremely underdeveloped muscles and wings, young birds may acquire a mature flight stroke early in development by initially relying more on their legs ...

Small birds are more energy-efficient than bats when flying. Researchers previously believed this was due to air resistance created by the bats' ears. However, biologists at Lund University in Sweden ...
