Hi Kathy, I have no idea if this would work, it's just a thought, but you might try a decoy feeding station for the bees. I used to keep honey bees and would feed them a sugar water mix in a zip lock bag laid flat and slit with a sharp knife. The surface tension of the sugar water kept it from leaking out and the bees would line up along the slit opening like pigs at a trough. If you use a gallon size zip lock bag the slit would be about six or seven inches. The bag is not full to bursting, either, maybe a quart or two in a gallon bag. Have the bag elevated; resting on something that would bring it to a height the bees like.you might have to experiment. And, with luck, it would lure them from the bird feeder. Bonnie Jacobs Lexington, KY PS I've been aware of the effectiveness of decoys since I have blueberries and raspberries in my yard which were completely ignored by the birds for as long as the service berry tree had berries. Since the service berries finished last week, I haven't had any more ripe blueberries or raspberries.the birds get them all.
