We bought this Oriole feeder recently and have been pleased with its ability to attract birds. We had a couple Orioles on it today and one of them was while I was sitting on the deck. We have also seen Humming Birds around it. We hung it on the old clothesline pole arm where the Finch feeder was and moved it to the other end of the arm. This feeder accommodates Grape Jelly jars that just screw into the feeder. It has a small agitator that brings the jelly down through some small openings and into the "plate". We have already got our money's worth by seeing the number of birds that we have. It seems that the more new birds we attract, the more the old ones show up. We spent quite a bit of time on the deck today and enjoyed Cardinals, Doves, Robins, Junco, Yellow Finches, Grackles, House Finches, Wrens, Humming Birds, etc. including some sparrows, Blue Jays, and a Starling or two.
