Bears are North America's largest and most impressive land mammals. The sight of a grizzly or black bear in its natural environment inspires fear and awe in the hearts of hikers, campers, tourists, and mountain residents alike. Mountain Bears follows a year in the life of North American grizzlies and black bears in their mountain habitat. The lively text and spectacular colour photographs of adult bears, cubs, and families provide a fascinating glimpse into the behaviour of bears, including details on mating and battles of the breeding season, hibernation and the feeding frenzies of autumn, and the complex and vulnerable lives of newborn cubs.
