Birds Flock to Grape Jam-boree

Baltimore orioles are well-known grape jam/jelly eaters. But several other birds are acquiring a liking for this sweet concoction. Namely, rose-breasted grosbeaks, house finches, male & female (and fledglings), catbirds, and, believe it or not, even robins! They keep me busy filling the jelly ports on my oriole feeder.
