American black bear [SEP] Dietary habits
American black bears often drag their prey to cover, preferring to feed in seclusion. The skin of large prey is stripped back and turned inside out, with the skeleton usually left largely intact. Unlike gray wolves and coyotes, American black bears rarely scatter the remains of their kills. Vegetation around the carcass is usually matted down by American black bears and their droppings are frequently found nearby. American black bears may attempt to cover remains of larger carcasses, though they do not do so with the same frequency as cougars and grizzly bears. They will readily consume eggs and nestlings of various birds and can easily access many tree nests, even the huge nests of bald eagles.
