I have posted shots of coots on Juanita Bay getting attacked by bald eagles and trying to get away while staying as a pack. I was back there a while back and there was a large flock of them out on the lake and they seemed to be constantly taking off and landing. They seemed to be spooked by something and bolting but then settling down before being spooked again. Strangely, there was nothing there. I think they were spooking each other. I did get some shots but it seemed that a video was a better way to convey what was going on so the clip below gives you some idea of how they were behaving.
