New paper on bat flight

Morphology of the bat wing

Bats are mammals that took to the wing around 65 million years ago. Some 15 million years later, they evolved the ability of powered flight. By the aid of particle image velocimetry, recent research on bat flight has revealed many intriguing facts  - for example that bat wakes are more complex than those of birds and that their aerodynamic efficiency is lower than in birds.

This, and much more is discussed in a recent review paper on bat flight, by Christoffer Johansson and Anders Hedenström, published in Journal of Experimental Biology.
