I've tried other oriole feeders but never had any visit. Since I have been using this feeder, I have been getting 2 - 3 orioles. The feeder holds sugar water and has indentations in the cover to hold jelly. (I use apricot preserves). You can add an orange half to the top by screwing the hanger through the orange and then into the feeder. In addition to orioles, I get catbirds, red-bellied woodpeckers, downey woodpeckers, and even a hummingbird using it. Easy to clean between fillings.
