It was wood ducks I was thinking of.
Look up “wood duck house,” they have a couple around the lake as part of the wildlife tax exemption.
I also have a pair of wood ducks that lives around my farm property. I’ve seen them many times, swimming with my ducks. We built a box year before last, something built a nest in it, but it was some kind of bird, not the wood ducks lol!
The wood duck pair did return this year, but I have not seen any ducklings with them. The males are outstanding!
