Utilizing straightforward and informative text with a sprinkling of "Fun Facts," the Animals of North America series introduces American wildlife to elementary-school readers. Though not identically organized, each volume uses four brief chapters to describe an animal's diet, habitat and range, physical traits and adaptations, social disposition (solitary versus group living), and life cycle. Most chapters dive straight into their topic of choice and then add supporting details. The chapter "Made for Water" in American Beavers notes several useful adaptations for their aquatic lifestyle, including transparent eyelids and watertight flaps that cover their ears and nostrils. With a clean, spacious design, a typical spread pairs accessible text with a large photo, diagram, or map. Each book also includes a short quiz in the back matter, making these books appropriate learning tools for the classroom or research projects.
