IMPORTANCE OF SCAVENGING ON MOOSE BY WOLVES IN ALGONQUIN PARK, ONTARIO
This paper addresses the importance of winter scavenging on moose (Alces alces) by gray wolves (Canis lupus) in Algonquin Provincial Park, Ontario. A high incidence (83%, n=30) of scavenging on moose was recorded in mid to late winter in 1987-1992. Moose fed on by radio-collared wolf packs and winter wolf food habits (n=892 scats) are related to sources of non-predatory mortality in the Park, namely winter tick (Dermacentor albipictus), train kills, and human hunting. Food habits of wolves imply that seasonal scavenging on tick-related moose carcasses is important to this wolf population during periods of tick infestation.
The role of scavenging is discussed in the context of a relatively small-sized predator (the Algonquin type of Canis lupus lycaon) limited to a large-sized prey species, the moose. Incidences of wolf scavenging in other studies are also presented.
