BLACK BEAR SCAT MANUAL
J Wildl Manag 59:584–594Īdorian AS, Kolenosky GB (1969) A manual for the identification of hairs of selected Ontario mammals. The preference displayed by wolves provides insight that wildlife managers can use to guide further investigation and assist with the development of strategies to ensure continued elk reintroduction success, and moose and white-tailed deer population sustainability.Īdams LG, Singer FJ, Dale BW (1995) Caribou calf mortality in Denali National Park, Alaska. Although we found black bear diet to be opportunistic during the summer, wolves in our study heavily utilized both juvenile and adult ungulates, however, among ungulate species, displayed preference for elk. Wolf diet was comprised mainly of ungulates (~ 73.2%), muskrat ( Ondatra zibethica ~ 8.5%), and beaver ( Castor canadensis ~ 14.6%), and although moose were at least 1.5 times more abundant then each of the other ungulate prey species in the study area, wolves preferred elk, using moose less than expected. We found that black bear diet consisted of more than 87% vegetation, and they were opportunistic, not selecting for any particular ungulate species in either adult or juvenile age class.

In addition, non-ungulate diet items were identified to obtain full diet composition profiles. We applied correction factors to frequencies of occurrence of prey items found in predator scat and related diet composition to the availability of ungulates, determined by fecal pellet transect surveys. We analyzed the presence of prey items in black bear and wolf scats collected over 3 years by examining prey hair cuticular scale patterns. We examined black bear ( Ursus americanus), wolf ( Canis lupus), and hybrids ( Canis spp.) prey preference in Ontario based on the availability of three ungulate species-elk ( Cervus elaphus), moose ( Alces alces), and white-tailed deer ( Odocoileus virginianus). Although black bear and wolf diets have been investigated extensively, prey preference has been less commonly examined, especially in analyses that take into account age class (i.e., juvenile and adult) of the ungulate prey. Ungulates often serve as a significant source of prey for many large mammal predators, and patterns of predation are known to influence population dynamics.
