The food habits of two packs of Vancouver Island wolves were studied between February and November 1978. Analysis of guard hairs in 616 scats showed that the major food of these wolves was black-tailed deer, Roosevelt elk, and beaver, respectively. Seasonal variation in the wolves' use of these three prey species and of different age-classes of ungulates were found. Composition of scats from den and rendezvous sites were significantly different from scats collected during equivalent periods along logging road and trails.
