American black bear (also called American black bear). Widely distributed in the forests of North America, it is active both in trees and on the ground. Omnivorous, it eats a high proportion of plant material and consumes a diverse range of foods depending on season and region, including fruits and acorns, insects, and fish. Usually solitary, most populations hibernate. Breeding involves mating in spring, with females giving birth and caring for young during hibernation; cubs are weaned at about six months of age. Because of its broad distribution and reproductive capacity it is assessed as having a low risk of extinction, although regional threats such as vehicle collisions exist.
