This attractive hummingbird feeder includes a built-in ant moat and has a removable ring perch. The ant moat, when filled with water, deters ants from reaching the nectar openings on your feeder. The large capacity, fluted, glass bottle holds 27 oz of nectar for your beautiful hummingbirds to reenergize from. The red base and ant moat, along with life-like flowers with red coloring, will attract many hummingbirds. This feeder easily disassembles for thorough cleaning and the wide-mouth bottle opening makes for easy pouring of nectar.
