"Wood ducks, buffleheads, barrow's goldeneyes, common goldeneyes, hooded mergansers and common mergansers are all cavity nesting ducks.
These ducks build nests in abandoned woodpecker holes or natural tree cavities caused by disease, fire or lightning. They will also use a constructed nesting box.
Don't have wood ducks in your area? A duck box may even attract other cavity nesting birds such as kestrels, tree swallows, great crested flycatchers or screech owls."
