A special feeder that attracts small birds like Chickadees, Titmouses, Nuthatches and Goldfinches. Eliminates large birds such as blackbirds, starlings, pigeons and Blue Jays, since there is not enough space for them to stay on the feeder. Easy to fill and clean this "Clingers Only" feeder protects the birds we love from disease. The entire lid of this feeder comes off (enabling you to fill from the top) and easily locks back into place. The large capacity holds 3.5 to 4 cups of seed. Made of heavy UV resistant thick plastic construction, this feeder will last for years.
