The Perky-Pet Prohibition Top-Fill Glass Hummingbird Feeder is a favorite of birders and hummingbirds alike. The wide-mouth opening and Top-Fill design ensure that filling is always easy and mess-free! Simply remove the lid and pour 36 oz of nectar into the wide-mouth opening to get your feeder up and running - there's no need to invert the bottle! The feeder is also easy to clean because it can be completely disassembled, ensuring that you can access every nook and cranny. While you enjoy time saved from filling and cleaning, your hummingbirds won't be able to resist the feeder's lifelike flower-shaped feeding ports. They are bright, soft and flexible just like the flowers they flock to in nature! Plus, with five ports, multiple hummingbirds can easily be accommodated at the same time. The flowers' long stem design also acts as a natural bee guard to keep bugs out. For your convenience, this feeder also comes complete with a gasket in the base to prevent any frustrating leakage.
