Black Bear (Ursus americanus)
Black bears prefer mixed deciduous-coniferous forests with dense under stories, but also are found foraging in a variety of habitats. During spring to autumn seasons, black bears tend to be more active during daylight and dawn/dusk periods, but in the month or so before and after the period of winter dormancy they are less active overall and more nocturnal. Bears overwinter in a dormant state in dens. Den sites are commonly under stumps and logs or in holes in hillsides, but may include hollow trees, rock caves, and drainage culverts, abandoned buildings, or in some regions even unsheltered depressions.
The use of the landscape changes with the season as food sources change. They become more active around wetlands and early green-up areas in the spring. Areas with large quantities of berries or tree mast crops attract bears in the late summer and fall. Bears often bed under large conifer trees with low-hanging branches on the edge of a feeding area.
