A poetry collection introducing animal architects that build remarkable structures in order to attract a mate and have babies. Many animals build something—a nest, tunnel, or web—in order to pair up, lay eggs, give birth, and otherwise perpetuate their species. Organized based on where creatures live—underground, in the water, on land, or in the air—twelve poems bring fish, insects, reptiles, mammals, and birds to life. Back matter includes more information about each animal.
