INTRASPECIFIC AGONISTIC BEHAVIOR BY ANNA'S HUMMINGBIRD

Abstract

Abstract In a previous general note we described lethal intraspecific behavior by a male Anna's Hummingbird (Calypte anna) during winter near the northern extent of the species' breeding range. This note reports another observation of agonistic behavior by a male of this species, under similar conditions, that resulted in “near death,” but which the victim apparently survived.
