Booklist Review

Gr. 5-8. The title of a study conducted by twin-brother naturalists Frank and John Craighead, Operation Grizzly Bear observed silvertip bear behavior in and near Yellowstone Park between 1959 and 1971. Balancing the scientific methodology with the drama of the animal-human encounters, Calabro's well-written chronicle recalls how the wildlife scientists utilized ear tags and, for the first time, electronic tracking collars to enable them to chart the bears' migration patterns. This hard data, coupled with visual observations, that took the humans miles cross-country, provided the basis for current scientific knowledge about grizzly bear diet, mating and cub rearing, hibernation, and life cycles. Introducing student readers to the political realities of wildlife preservation and research, this review will do just what the naturalists set out to do in their research--spur further study of grizzlies and inspire determination to preserve the species. --Beth Herbert
