Marys Feeders has been making quality bird feeders since 1987 and they are still the best! The uni-body design makes this feeder exceptionally easy to fill and clean. By using hexagonal raised diamond geometry of ports we are able to prevent bees from taking over the feeder which makes it even more desirable to your hummingbirds. We designed this feeder to hold 12 oz of nectar (sugar water). Marys Feeders hummingbird feeders are handmade in Wisconsin from impact resistant plastics and they come with instructions for making your own nectar. Pair this feeder with our SCH-61 Suction Cup Bracket for up close, 360 degree viewing. Expect a lot of activity!
