For the last week or so my hummingbird and oriole feeders and 1 birdbath(one without the fountain) have been just a buzz. Anyone have any idea what kind of bees these might be?? They are not at all aggressive, just seem to be happy sucking on the nectar that is in the feeders. I don't really mind since we are in such a drought I am sure the little guys need water.Interesting though, these feeders sit right in the middle of my flower garden and the bees don't go anywhere near the flowers. I'm just hoping they are not a "bad" kind of bee. Anyone else experiencing this problem??
