This classic birdfeeder with its pinch waist design has been a fashionable favorite of hummingbird enthusiasts. The Perky Pet Clear Plastic Hummingbird Feeder features 3 feeding ports and holds 8 ounces of nectar. The clear, shatter-proof plastic reservoir of this birdfeeder makes it easy to monitor nectar levels and unscrews easily from the feeder base for quick cleaning and filling. For best results, use Perky-Pet Instant High Energy Nectar. This specially blended nectar is easy to use, requires no boiling and stays fresh longer. This birdfeeder may be cleaned with the Perky-Pet Cleaning Mop. Remember to clean your birdfeeder at least twice a week, more often in very warm climates or seasons.
