Experienced and novice birders will delight in David Allen Sibley’s colorful bird portraits as they find favorite backyard birds while piecing together a 1,000-piece jigsaw puzzle. Each of the birds in this piece of art–from the Great Horned Owl to the Goldfinch–is displayed in proportion to the flock of birds around it, making this puzzle a unique educational look at the sizes of a variety of North American birds. The colorful, challenging puzzle promises hours of fun packaged in one sturdy box, and the assembled result spans a generous 20 x 27 inches.
