We bought this feeder, but anything similar would work. We don't fill the hopper with jelly, we just put a few of spoonfuls in the tray every morning. If you are lucky you might also attract little Orchard Orioles, which is cool because they aren't real common. Chickadees will also eat jelly.
I just took this photo (7:330 PM) and I had put three heaping tablespoons of jelly in it this morning. They are really chowing down.
