This is the only field guide to provide comprehensive coverage of the mammals of Central America and Southeast Mexico. This edition features 21 new species accounts, including nine for bats. Four new full-color maps show parks and protected areas, biomes, elevations, and habitat loss. From Funnel-eared Bats and Spider Monkeys to Climbing Rats and Pocket Mice, Anteaters and Sloths to Sperm Whales and Ocean Dolphins, the guide fully describes every known regional species. Over 150 range maps have been updated along with present conservation status and habitat information. The new book features descriptions and measurements, where and when each species might be found, what type of nests or dens it uses, feeding habits, and reproductive cycles. Highlights include the 49 (previously 48) vibrant full-color animal illustrations, most painted directly from live subjects. Tracks and feet appear on facing-pages. A glossary and updated bibliography round out the usefulness of this indispensable guide.
