Black bear Cub picking white bark pine cones from top of snowy tree. The American black bear, Ursus americanus, is one of eight species of bear in the world and one of three on the North American continent. It presently lives in much of the forested parts of the U. S. and Canada. They can be black or cinnamon brown, and rarely blue or white. They are like people and will eat almost anything. The Whitebark pine is considered a keystone species in the Yellowstone ecosystem. In fact, a bear’s fall nutrition is intertwined with the availability of whitebark pine seeds.
