LETHAL INTRASPECIFIC BEHAVIOR BY ANNA'S HUMMINGBIRD

Abstract

Abstract Intraspecific agnostic behavior is well-known in hummingbirds; however, lethality in North American species is unreported. Here we describe an observation of a lethal attack by a male Anna's Hummingbird (Calypte anna) on another male of the same species during mid-winter near the northern extent of the species' winter range.
