To see a fog shrew, should a mammal watcher go to Muir Woods National Monument? If a family is planning to visit Yellowstone National Park, what animals can they expect to show their children? When should a photographer visit to get a shot of a gray fox? A finder's guide (rather than an identification guide), this book tells people interested in observing mammals how to look, where to go, and what they are likely to find there. The bulk of the book is made up of two sections: the first includes regions of North America, highlighting the best places to look for mammals. The second section's accounts of each of the more than four hundred species of mammals covered include detailed directions to specific parks, refuges, and other locations; the best times of day (or night) to look; and much more information specific to each mammal.
