Oftentimes when we glimpse an animal in the wild, we have no idea what we’ve seen. We want to know, and field guides are an ideal aid for identification. But when we want to know more about the lives of these animals—their natural histories, their place in the larger ecological community, and where to look for them in the future—we can turn to Behavior of North American Mammals. This exciting addition to the Peterson Reference Guide series is highly readable and full of fascinating facts. For example, when an opossum plays dead, it isn't pretending: opossums actually do enter a catatonic deathlike state. Armadillos sequester air in their guts, blow up to twice their normal volume, and paddle across the water. And beavers stockpile food for winter by catching it in beneath a raft of branches, which gets frozen in place and keeps them well supplied until spring. A guide not to identifying mammals, but to understanding what they do, Behavior of North American Mammals provides detailed information on more than 70 species of mammals and includes illuminating and attractive photographs and drawings. Comprehensive, authoritative, and accessible, the book includes information on daily and seasonal activity, food and foraging, home range and habitat, communication, courtship and mating, development and dispersal of young, interactions with their own species, and interactions with other species.
