Cannibalism of a yearling polar bear (Ursus maritimus) at Churchill, Canada

Abstract

An adult male polar bear (Ursus maritimus) was observed on 17 October 2000 consuming a yearling polar bear at Churchill, Manitoba, Canada. On 21 October 2000, a subadult male fed on the remains of the same bear carcass. Circumstantial evidence suggests that the adult male killed the yearling, although it is possible that he took the kill from another bear.
