"Whether we are able to look at them face to face, on television, or in the hundreds of illustrations provided here by Daniel Otte, this guide allows us to understand what animals do and what their behavior means. Drawing on his own extensive fieldwork and on the research of many other scientists, Richard Despard Estes describes and explains the behavior of four major groups of mammals. Estes's remarkably informative guide is as up-to-date (as of 1992) for the zoologist as it is accessible for the interested onlooker."
