The infectious enthusiasm of these mother-daughter naturalists and the child-oriented organization of the text make this an agreeable jaunt Down Under. The Darlings' observations, acquired from several trips to Australia and Tasmania, are organized into short chapters discussing the kangaroos' unique movement, breeding, diet, and adaptability. Eight species are highlighted, from Lumholtz kangaroos, which dwell in and occasionally fall from trees, to quokkas, which resemble rats, to the more familiar grays and reds. Emphasis is on kangaroo behavior, described in the zesty, conversational text. Such "science" topics as classification, physiology, and habitat are adequately covered (to the satisfaction of middle-grade report writers) but are always introduced to support and illuminate discussion of behavior, never for their own sake. A small map of the Darlings' study sites, a fact page, and a brief index are included. At least one clear color photo accompanies each double-page spread and is well correlated with the text.
