In this book Matthias Breiter takes us on a fascinating journey through an entire year in the life of North America's great bears - the black bear, the brown bear and the polar bear. Beginning in February when the bears first wake from hibernation and give birth, we watch these magnificent animals hunt, feed, play, mate and breed until the return of winter, when the need to hibernate begins the cycle again. Bears are, by nature, solitary creatures and prone to fight only if threatened. They have no significant natural enemies. But human beings have reduced a once great population to a small remnant. Bears is packed with facts and details gained over a lifetime of study and photography by its internationally renowned author.
