Every Spring the Wood Ducks come to Oakwood to nest and raise their young. There are at least four pairs of Wood Ducks that are seen in our backyard. Our mornings since March always include checking our trees for the ducks. Sometimes we get lucky and catch a photo of them, but never have we seen more than one female on a nest box at a time. Obviously Oakwood needs more Wood Duck boxes. Gunnar is working on it.
Here is one of the males hanging around in our trees. The ducks are definitely in pairs.
The females below are next door at my sister Linda's nesting box.
