Beloved birds of North America take center stage in this large jigsaw, featuring illustrations by bird expert and artist David Allen Sibley. Each of the 50 species here—from a swan, pelican, and heron to a warbler, chickadee, and hummingbird—is depicted in proportionate size to the others, letting you compare them directly. (The background offers an extra challenge, as there is only a faint visual texture to guide you.) When finished, the puzzle measures 27 x 20 inches, and a large folded poster of the full image is provided.
