@FBM,
I was thinking of the coots that used to play in the Venice (california) canals..
I've got photos somewhere. The moorhens reminded me of them.
I used the word cootie, as a made up adjective - that's my way, toy with words - referencing from my childhood word cootie and the word cutie, but I don't really know the meaning of that word, cootie. I think "he's got cooties" was something like "that boy has lice", but I don't know that for sure.
