Orientation Behavior of Four Species of Waterfowl

Abstract

Initial investigations of the orientation of Mallards (Anas platyrhynchos) by the sun and stars were made in the fall of 1956 (Bellrose, 1958a). Since then, data from continuing experiments with this species, as well as initial experiments with Blue-winged Teal (Anas discors), Pintails (Anas acuta), and Canada Geese( Branta canadensis), have added materially to the information available on the orientation behavior of waterfowl
