The Perky-Pet Grand Master Feeder features six feeding ports, a wide-mouth design and holds 48 fl oz of nectar. The Grand Master truly is the Granddaddy of them all. With its large capacity for nectar, hummingbirds from all over the neighborhood will be flocking to your house! The clear, shatter resistant plastic reservoir makes it easy to monitor nectar levels. The wide-mouth design allows for easy refilling and cleaning and unscrews easily from the feeder base. Remember to clean your feeder at least twice a week, more often in very warm climates or seasons.
