Coots, sometimes called Mud Hens, are fun to watch. The coot is mainly an herbivore. But not entirely. In the video you can see it diving.
The camera, a Canon Rebel, did a good job. You can actually see the silvery body of the coot coming up from under the surface in one of the video clips. They stay underwater quite a while. Not as long as cormorants. The coot dives down and fetches vegetation which is a large part of its diet.
They have ruby red eye eyes and their adult feathers are slate grey. Their feet look like chickens feet that tried to be a ducks foot and gave up when it was half way done. When they congregate in the yard they look like a flock of black chickens.
They're fun to watch and quickly learn if they can expect a hand out.
