Here in Pennsylvania they aren't hunted and are considered inedible. In a handful of states, hunting them is considered sport and the birds are heavily hunted, though the meat still isn't eaten. I read one report that indicated about 720,000 were killed for sport in a recent year, especially in the south. I come from a family of hunters and hunted myself when I was younger. I've never understood the idea of killing something you didn't (or couldn't) eat.
I saw two of the coots move into the sticks you can see in the background of this photo and walk out of the water, balancing just above the water line. Coots are related to moorhens and even remind me a bit of the southern waterbird, the jacana, when they are out of the water. I see them often enough in open water, but they seem to especially like areas where they can hide in bushes and shrubs along the the edge of the water. They aren't glamorous by any means, but they are still a cool bird to see and watch.
