Hummingbirds flying upside down. Slugs mating while suspended in midair. A muscular mole turning somersaults in its tunnel. So much is happening, minute by minute, in your own backyard. In this Uncommon Field Guide, author Patricia Lichen combines standard field guide information about habitat, appearance, and range with delightful and engaging descriptions of the little-known facts, surprising details, and amusing-even bizarre-tidbits rarely found in ordinary field guides.
