Stokes Select Deluxe Hummingbird FeederThis 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. 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. Includes S-hook (stored in the base) to hang from any hook or hanger.Stokes Select Tips: Tip 1. Keep ant moat filled with water to deter ants from reaching nectar, since ants are reluctant to swim.Tip 2. Remove feeder perch in cold weather so hummingbirds will be warmed by flying before they drink the cold fluid.
