WOLVES

Varieties, life cycle, pack and hunting behavior, and the current status of this endangered predator—although with what may seem too many transparently rhetorical questions (``Are wolves savage and destructive hunters of people and livestock?'') and fillers (``After wolves kill a large animal, they may rest for a brief time or eat right away''). Without attribution, Simon states that ``...there is no record of a healthy wolf ever trying to kill a human in North America.'' In Gray Wolf, Red Wolf (1990, for slightly older readers), Patent is more precise: ``there is no record of a healthy wild wolf attacking a human.'' Patent also does a better job of stating the case for and against reintroducing wolves in national parks. Still, though his text isn't up to his usual high standard, Simon again selects outstanding photos—this book's strongest and most appealing feature. (Nonfiction. 8-10)
