Gr 4-8 This well-written and magnificently illustrated account of the wolf pack discusses the social hierarchy among group members, care of the young, communication, hunting and the relationship with competing packs. One especially fascinating chapter gives a historical perspective of the wolf in mythology as well as attitudes toward these often misunderstood animals and how they have led to the wolf's present endangered status. A final section explains how biologists locate and observe wolves in the wild by using airplanes and radio tracking collars. The combination of clear, well-organized text, diagrams and good quality color photographs make this an excellent candidate for school or public library collections. The addition of the historical background makes this book a good complement to Scott Barry's The Kingdom of Wolves (Putnam, 1979) and Jane Rockwell's Wolves (Watts, 1977; o.p.), both of which are good studies of behavioral patterns in wolf packs.
