Tractor birds

Today as I was coming back from getting lunch I passed a large flock of cattle egrets gathered on the side of the road. Of course I pulled off to the shoulder to get a few pictures since I had my point & shoot with me. I noticed as I pulled off a tractor across the little pond was starting to cut the grass. The birds started to fly over to where he was cutting. He must have been stirring up the bugs. I'm sure he's used to having birds following him around when he's cutting the grass but it looked so funny to me to watch. There was a great blue heron hanging out with the cattle egrets.
