How can a bat pick a small insect off of the surface of a leaf in total darkness? Why do shrews no bigger than a thimble eat more than their body weight each day? And how did a prehistoric pig-like animal evolve into the pronghorn antelope, one of the world's fastest creatures? Profiling more than 150 animals of Canada and the northern United States, Adrian Forsyth provides substantial yet accessible information on the habits and most interesting characteristics of these creatures, and outlines the threat posed to them by humans. Here too is basic information on the animals' diets, evolution, habitats, and geographical distribution, and all of the animals are depicted in stunning color photographs.
