The largest wild member of the dog family, the grey wolf stalks much larger mammals, such as the elk, caribou and moose. How does it succeed? Built to run, the long-legged wolf on the hunt uses its powerful sight, hearing, smell and physical strength. But, like the domestic dog, the wolf is a social animal: it lives in a pack. In this fully illustrated introduction, young readers will learn how group living makes sense for the wolf, allowing it to form strong bonds and share tasks like rearing its young, finding food and communicating over long distances. They'll also find out how habitat destruction, poisoning campaigns and hunting have reduced grey wolf populations in much of North America. Full-colour photographs provide close-ups and action shots, while the engaging text, sidebars and captions tell the life history of an animal that researchers agree has one of nature's most engaging personalities.
