The Sky Cafe Bluebird Feeder, with its beautiful sapphire blue dome, is designed to attract bluebirds, orioles and their fledglings. Carefully protected from larger birds like robins by its wire-formed cylinder, mealworms are held within a removable cup in the center of the feeder. The durable 100%-recycled Plexiglas lasts for years and years. Comes with 2-ft hanging chain and is pole mountable.
