XiXi Shop Mary's Feeders has been making quality bird feeders since 1987 and they are still the best We have been making these great feeders for 34 years now and our hummingbird feeders have stood the test of time. The NJ-1 works better than any other feeder because we use hexagonal raised diamond geometry of ports that allows the hummingbirds to visually locate the nectar-like they do when they look into a flower. 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. The unique design of our Mary's Feeders NJ-1 allows you to watch hummingbirds using their beaks and tongues within the tube so you can actually see the feeding process happen. Did you know a hummingbirds tongue can reach almost an inch past its beak? Each feeder has a 12 ounce capacity for Nectar General dimensions (Red lid is 8 inches by 8 inches).
