How Bats Keep Out Echo Clutter (2 of 7)

Caption

A big brown bat (Eptesicus fuscus) flies in an obstacle test with rows of vertically hanging plastic chains. The bat's head, ears, and sound beam are aimed toward the open path to the front. This image relates to an article that appeared in the July 29, 2011, issue of Science, published by AAAS. The study, by Dr. Mary E. Bates of Brown University in Providence, R.I., and colleagues was titled, "Bats Use Echo Harmonic Structure to Distinguish Their Targets from Background Clutter."
