American Coot, Fulica americana. Admittedly, they look nothing like their white beaked, solid black parents. I suppose they're kind of cute in a bald, frizzy sort of way. Certainly, nothing on the level of duckling cuteness. The parents are hyper aggressive in chasing away the other birds from the nest. I almost thought one of the parent coots might hop out and give me a nip but, at the last minute, it swam on by, apparently deciding against leaving the water to chase the tourists.
