Bats go quiet during fall mating season

Giving someone the "silent treatment" during courtship might not be the best strategy for romance. But, new research shows hoary bats fly with little or no echolocation at all as a possible mating-related behavior.

The findings challenge the long-standing assumption that bats are reliant on echolocation, the use of high-frequency sounds to detect objects, for nocturnal navigation. The research also might help explain why thousands of bats are killed each year by wind turbines.

"Inconspicuous Echolocation in Hoary Bats," a new study by Wake Forest University research assistant professor of biology Aaron Corcoran and Theodore Weller of the USDA Forest Service's Pacific Southwest Research Station, appears in this month's Proceedings of the Royal Society B.
