In this volume Stanley P. Young completes his series of monographs on the major predatory mammals of North America. As in his earlier works, The Wolves of North America; The Puma, Mysterious American Cat; and The Clever Coyote, Mr. Young writes with the authority of a field biologist who has studied his subjects for more than a quarter of a century in the intimacy of their own habitat, from coast to coast and from the northern limits of their range in Alaska and Canada to the deserts of Mexico.
