title: Sensory biology: echolocation from click to call, mouth to wing.
abstract: Echolocators use echoes of sounds they produce, clicks or calls, to detect objects. Usually, these signals originate from the head. New work reveals that three species of bats use their wings to generate echolocation signals.
