Abstract

Recently-metamorphosed leopard frogs (Rana pipiens) showed an ability to orient along their Y-axis when able to view the sun, but appeared to move randomly under nocturnal skies. Froglets trapped moving away from their natal pond in the season's first dispersal wave oriented in the direction of their movement when tested immediately after capture with the sun visible; the directional choice gradually reversed over a period of five days. In later dispersal waves froglets preferred the homeward direction.
