This little bird-watching kit from Outdoor Discovery has everything kids need to find feathered friends outside. Each Little Birder Kit includes 1 pocket-sized, 20-page Guide to Backyard Bird Watching booklet and a pair of 4.5 x 4.5-inch sport binoculars. The binoculars have a center-focus design, making them usable on close-range objects and easier for kids to view through, with 4X power to bring kids up close to birds in a whole new way. All 20 bird identification cards include a photograph of a unique bird species and some fun facts.
