Feeding hummingbirds can be an incredibly rewarding experience, but it can also be time consuming. With the Perky-Pet yellow flower top fill hummingbird feeder, feeding the birds has never been easier. The unique top fill technology allows you to simply unscrew the cap, pour in the nectar and you're ready to feed the birds. This design also makes it easy to clean. The four soft flower shaped feeding ports offer a more natural feel and hummingbirds will be attracted to the bright yellow color. The shatter-resistant plastic bottle has a 16 oz nectar capacity to keep your hummers full and happy. Plus, with a built-in ant moat, ants will never be a problem for this feeder.
