I’d heard of coots. I’d seen a few coots. But, before we anchored at Mildred Island this month, I never experienced entire flocks of coots swimming and dancing on the waters around me. Here’s a link with information about the American Coot:

You never know what the flock is going to do. After a few days anchored, I did notice that they were especially fun to watch at sunset. So I turned on the video setting in my little camera and this is what I saw. Swimming, dancing, and chasing each other. That’s what they do, it seems.
