Abstract

The various species of bats analyze the acoustical parameters of their orientation sounds in order to detect and localize targets. Behavioral studies indicate that echolocation also enables bats to obtain information on other target features which they can use to distinguish different targets and perhaps even to identify behaviorally relevant targets (summarized in Schnitzler and Henson 1980).
