Grizzly Bears [PDF ebook] 

They’re huge, dangerous, and can smell food from miles away-they’re grizzly bears. Grizzlies are found in many parts of North America. Known by the powerful hump of muscle on their backs, grizzlies spend much of the year bulking up their body fat in preparation for their winter hibernation. This book takes a glimpse into the fascinating lives of these fierce predators, from catching fish to raising cubs.
