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 bottle holds 29-Ounce of nectar for your beautiful hummingbirds. You can fill your feeder with less nectar if you have fewer hummingbirds visiting. The life-like flowers with red coloring are a sure attractant for hummingbirds. This feeder easily disassembles for thorough cleaning and the wide-mouth bottle opening makes filling easy.
