It's been an especialy productive nesting season on my property this year (with my property being but 1/3 an acre). More than anything, developing/planting a native woodland garden has helped immensely. Early spring found 2 robins nests (in a threadleaf cypress and a cedar), 2 separate catbird nests (in yews on either side of the property), my first ever Balt. Oriole in one of the oaks. I found one of the Catbirds carrying food (this weekend) which to me is indicative of a second brood. Also found another robins nest in the crotch of a styrax. Today, I found a cardinal book out of that part of the garden on the north side of my house. Figured it was hunkered down nesting in a huge skimmia (40 yo) patch. Later today found that the nest was in the crotch of a sizable Rh. nova zembla. Carolina & house wren nested nearby (though I cannot say definitively they were on the property proper). The ruby throated hummingbird was also quite clost to the property. Just a terrific year.

I also have a larger than normal population of Catbirds this year. Usually I see one every now and then, but this year I'm seeing four at a time.

The orioles that pass through here, if given the choice of nectar, orange, and grape jelly, almost always choose the jelly. Only the first oriole this season ate a small amount of orange when the jelly trays were empty. The only problem is I don't get many orioles(8 total in 7 weeks) and it doesn't take them long to eat the jelly. I've had one oriole for the last week so he must be nesting in the area(I haven't seen a female so maybe she's sitting on eggs all day). However, he only visits my feeder for about ten seconds a few times a day. The catbirds, on the other hand, spend MUCH more time at the feeder eating jelly. I have seen them less in recent days as they have shifted to some other foods like serviceberries.

Our catbird loves jelly too (Welch's grape)! Maybe one of those pretty jars you hang up with sugar water in the bottom, hung in the general vicinity of the feeder, would help distract the wasps/bees (and eliminate them). The necks on these jars are narrow, a bird couldn't go in but a bee could. I suppose you could even put jelly in the jar? Good luck!
