There were a few in a pen at a convalescent home at which I worked summers and vacations in CT. More than once I wondered if someone was in trouble! Killed many work hours chasing them through the woods when they escaped! There are also several on Pine Island here in SW FL.Loud, obnoxious - yes. Also a great source of fly tying material and in some regions table fare. They have one cry that sounds just like someone screaming "Help!" and if you hear it for the first time belly deep in the river and wrapped with fog it'll lift the little hairs on the back of your neck.
