The attractive Deluxe Hummingbird Feeder includes a built-in ant moat and has a removeable ring perch. The ant moat, when filled with water, deters ants from reaching the nectar openings on the feeder. The large capacity bottle holds 33 oz. of nectar for your beautiful hummingbirds. This feeder easily disassembles for thorough cleaning and the wide-mouth bottle opening makes filling easy. Feeder includes a S-hook to hang feeder from any Stokes Select accessory.
