More seasonal sightings come in.
We have a quarter acre pond in our back yard and have several year-round mallard residents. This was the first time we've seen the mergansers. One male kept close watch on the female and kept the other males at bay, sometimes just circling and a few times with outright tussles. They stayed Tuesday and Wednesday, disappeared Thursday when a coat of ice covered the pond and so far one has returned today. They did lots of diving and sleeping.
