This is Mr. & Mrs. Mallard who have taken a shine to our tiny little back yard pond. Sometimes they are out there swimming around at 6 a.m. Other days they show up around 7 p.m. and swim around and preen until the dogs chase them out. We don't mind as long as they don't try to lay eggs in the yard. That would be foolish. They don't strike me as particularly bright, but I love the duckies anyway.
