This delightful hummingbird feeder with its metal rooster and four blue glass votive-style nectar holders will be the toast of the town and a favorite of hummingbirds. The Avant Garden Harvest hummingbird feeder, part of our Heritage Collection, is constructed from metal and glass. The four pot-style glass nectar containers hold a total of 10 oz. of nectar and contain a feeding port on each one. For best results, use the Perky-Pet™ Instant nectar. This specially blended nectar is easy to use, and requires no boiling. The feeder may be cleaned with the Perky-Pet™ Cleaning Mop. Remember to clean your feeder at least twice a week, more often in very warm climates or seasons.
