Although black is the most common color of this bear, its color can range from light brown to dark brown. There is even a population of white Ursus americanus living on a remote island off the west coast of Canada.
A solitary, predominantly vegetarian creature, the black bear uses its keen sense of smell to search out fruit, nuts, berries, and roots.
However, this bear will also eat insects, honey, fish, and small mammals when the opportunity arises.
It is an excellent tree climber and despite its size regularly ascends to the treetops to eat.
From late fall until early spring, the black bear exists in a state of torpor.
