This is a coot.

When I was young, we called old people "coots." As in, "he's just an old coot." I think we mostly referred to males as old coots. Eccentricity intensified the quality of being an old coot. 

Then I moved to Virginia and discovered that there is another kind of coot. I see a lot of them on the water. They don't seem particularly eccentric. 

Another childhood image burst because of a new experience.
