This book will make children feel as if they have access to their own nature museum, with seven different US habitats on display: desert, grassland, alpine tundra, arctic, salt marsh, kelp forest, and swamp. For each habitat, Duncan (illustrator of Susan Cooper's Unseen Rainbows, Silent Songs, 1995, etc.) provides two introductory spreads of descriptions and small colored vignettes of typical plants and animals, and then presents a scenic spread of those same plants and animals in context. She is careful to note areas in which she took artistic license: by cramming so many species into one scene, and by portraying nocturnal and diurnal animals together. Readers will delight in locating dozens of creatures hiding and hunting in the landscapes; the realistic drawings are a trove of information to observe and digest.
