Now available in a mobile version, the official Peterson Field Guide to Mammals of North America app goes where you go.

Time-tested and uniquely useful, the Peterson Field Guides series has key features that set it apart from the competition.

THE PETERSON IDENTIFICATION SYSTEM
▶ Roger Tory Peterson's exclusive system shows exactly what features to look for to tell one species from another.
▶ Designed to work in the field, every illustration and every word, is directed to that end.

DETAILED DESCRIPTIONS
▶ The most comprehensive, in-depth, and current guide to North American mammals. Includes extensive information on mammal behavior.
▶ Covers the more than 450 species of mammals found in North America north of Mexico, including those that live in near-shore waters.
▶ Includes vocalizations of more than 100 species of mammals.

ACCURATE ILLUSTRATIONS

▶ Includes full-color illustrations, black-and-white drawings, and detailed range maps.

EASE OF USE
▶ Swipe through page after page of illustrations grouped together by similarity so you can identify mammals faster.
▶ Not sure what you’re looking for? Browse species by mammal type or alphabetically and then toggle the display between animal groups, tracks and skulls.
▶ Looking for something specific? Search by species name, family, or mammal size, and refine your search by location, habitat, abundance, and mammal type.
▶ Make our app YOUR app — make custom lists of mammals via email or social media, add your own photos, share lists with friends, record your sightings, and maintain a life list.
