The Perky-Pet Top-Fill Hummer’s Favorite 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, including the ports and perches, ensuring that you can access every nook and cranny to prevent mold buildup. 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! Each port is accompanied by a removable perch so birds can rest while they dine. Plus, with six feeding stations, multiple hummingbirds can easily be accommodated at the same time. The flowers’ tapered design acts as a natural bee guard to keep bees out of the nectar reservoir. There’s also a built-in ant moat. Simply fill the cap with water to prevent ants from making their way to the ports. For your convenience, this feeder also comes complete with a gasket in the base, creating a nice tight seal to prevent any frustrating leakage.
