Mostly there are only mallard ducks & canada geese around here. Those are the only birds I ever see on the Mississippi. But lately from time to time I’ve seen a couple of wood ducks around. Actually, I usually see them hanging around in little ponds next to the highways. They like to huddle in little groups of 3 or 4 on the edge of a dock & sleep, but if anything startles them they jump into the water & paddle away. Their feathers are a huge arrangement of different colors; of course the males are quite a lot more stunning than the females, but the females are a sort of shimmering blue-gray with white wing bars. Check out the link to hear their call. It’s not at all what you’d expect from a small duck: http://www.allaboutbirds.org/guide/Wood_Duck/sounds.
