I was at the yard the other day and bees were flying real well. Then I noticed a couple of swallows working the air and picking off bees here and there. And then to my surprise came along a tiny cluster of agitated bees - maybe 50-100 - chasing a swallow. The cluster was all around the bird, and you could see her it trying to shake them off. I thought that was pretty cool, especially since I was to have some queens emerge in a day or two. Anybody else seen this before? I wonder if the bees were all from the same colony, or different ones? Either way, it was a pretty cool sight to see.
