One of eighteen in the “Crabtree Connections,” a series of short reference books for early readers that focus on a particular area of geography, science or history. This edition takes readers on a backyard tour of fauna and invertebrates that contribute in various ways to building a green environment. Some of the kinds of critters include Backyard Heroes, Marvelous Munchers, Hungry Hunters, Amazing Movers and Radical Recyclers, for instance. The two pages devoted to each area include three or four short paragraphs about the animals, boxed items of particular focus and various color photographs.
