Have had the oriole feeder up for a few years and it has always been worth every last jar of jelly we have gotten.
This year I have two sets of Baltimore's and one set of Orchard Orioles. Pretty interesting. But tonight was a first for me. Had a pair of grey catbirds enjoying the jelly. In years past from time to time I've had a humming bird decide it liked grape jelly better than it's own private nectar, but I've never seen other birds dip into the jelly before.
Anyone else have odd customers at their feeders? Just wondering.
