The designer kept making improvements until he figured this feeder was perfect — both for hummingbirds and for you! The two-piece plastic base makes cleaning and filling quick and easy, and it does not drip. The feeder's four ports have built-in bee guards and will accommodate more than one bird at a time. The top has a hook that makes it easy to attach to a hanger, so hanging from a branch or pole is easy; and the top unscrews so you can set the feeder upside down on a flat surface for filling. Plus, the perch has a double ring so hummingbirds can choose just the right spacing to perch on. The glass bottle is colored red, so it attracts the eye of hummingbirds without you having to use dye in your nectar. It even has decorative etching of a hummingbird and flower just to please the eye! Holds 12 ounces of nectar. 7¼″ H, 6″ W.
