註釋Outlining the differences and similarities among the various species of North American bears, this book makes a plea for the preservation of bear habitat that is quickly disappearing. It discusses in detail the natural history (including range, diet, personality traits, breeding and social structure), the present and historical interaction with mankind, and the threats to black, brown and grizzly bears.
