Black bears are large mammals, averaging between 100 to 150 pounds for females and up to 300 pounds or more for males. Some black bears weighing more than 600 pounds have been reported. The general coloration of the black bear is bluish black but occasionally they may be brownish or even cinnamon colored. The muzzle is brown and there may be a white patch on the upper region of the chest. The tail is short, the eyes are small, and the ears are small and rounded. Black bears walk flat-footed and are known as plantigrades. Each foot is tipped by long, powerful, non-retractable claws.
