I was out by one of my hive stands this morning and got to watch a flock of Purple Martins flying back and forth threw the flight line of the bees. They are obviously eating bees!. I read that the Purple Martin will eat it's weight in bugs daily. I hope this is not going to be a constant thing. I don't see as there is any thing that I can do, short of some wing shooting, and that is illegal. And I thought Varoa mites were bad!
