Abstract

Female green tree frogs readily localized an elevated sound source. Prior to hopping on sticks that formed a three-dimensional grid, females usually scanned laterally with their heads elevated after first scanning in the normal, nonelevated fashion. Unlike mammals and owls, frogs lack external anatomical features specialized for resolving vertical and horizontal components of source direction.
