This is the only field guide to provide comprehensive coverage of the mammals of Central America and southeast Mexico. The fully revised second edition includes 21 new species, as well as updated illustrations and distribution maps. Each species account provides measurements, descriptions, and comparisons with similar species, and is accompanied by a range map showing where the species can be found in the region.

The 49 full-color animal plates contain similar species portrayed to scale on the same plate, with tracks and feet shown on the facing-page. 4 new full-color maps provide visual views of parks and protected areas, biomes, elevations and habitat loss, as well as a political map of the region. The book also features a detailed introduction with sections on how and where to find mammals and a listing of the most endangered species in the region.
