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.
