Black bears, the most common and widespread in Canada, may also be brown, cinnamon or even white. Males weigh 80-250 kg: females are 10% lighter.
In the United States, black bears mainly live in the Ricky Mountains and the Appalachian Mountains, in the Northeast and on the West Coast. Black bears also live in parts of Alaska.
Bears live a solitary life for the most part. Bears are only found in groups in families, during the breeding season, or at sites with abundant food. Black bears maintain defined home ranges or territory that overlap and may be defended against intruding.
