During the winter, we had an unusual problem with large numbers of bees coming all over the feeder. They seemed to be desperate and would crawl inside the ant guards. Once inside them, it was hard to get them to exit the bee guards. Those things didn't keep the bees from swarming all over the feeders anyway, so I stopped using them. And the titmouse likes it this way.
We had that one Audubon Oriole at the bird feeder for one day earlier in the year, but don't know if it came to the hummer feeder.
