For anyone who's wondered which bird is singing, or eating the sunflower seeds, this informative, beautifully designed set of cards will answer the call. The stunning photographs adorn 36 cards representing 18 pair of backyard birds. The birds are identified with facts, and categorized into color-coded groups of songbirds, woodpeckers, hummers, little chirpers, tricksters, and water birds. The 32-page booklet describes how to identify birds by color pattern, habitat, behavior, or field marks, and offers a map and resources. Oh, lest we forget, there are rules for three different card games.
