The Way Bats Fly.

Scientists found out that bats fly very differently from the way birds fly, and underscored the different evolutionary paths bats and birds took in developing flight:

A bat, Glossophaga soricina, in flight in a wind tunnel at Lund University, Sweden. The velocity field induced by the wingbeat is shown superimposed and to scale. The bat wake reconstructions have features that have not been observed in similar-sized birds. Membranous and feathered wings of natural and engineered flyers may have significantly different aerodynamic properties.
