The Birds Choice 12 Oz. Oriole Fest Oriole Feeder works perfectly with great functionality and aesthetically pleasing.  It holds half an orange, has four feeding ports, jelly trays, a built in ant guard, 12 oz  necter capacity and on top of all that is dishwasher safe.  So far we've had Orioles, House Finches and Hummingbirds using the bird feeder.  Considering the variety of birds using the feeder we will be buying additional ones in the future.
