Predation of a Bat by American Crows, Corvus brachyrhynchos

Kara L. Lefevre


This report documents predation and possible group hunting of a bat by American Crows (Corvus brachyrhynchos). I observed a group of several crows appear to cooperate in order to ground and catch a bat. Predation of bats by birds in North America is relatively rare, and bat predation by crows has not been previously reported. A cooperative attack would be consistent with other group behaviours of the species, including territoriality, breeding and foraging.
