About 8 AM: Lots of activity with everyone in breeding plumage.  Saw a dozen or so ring-
necked ducks who have been hanging there for some time.  Two pairs of hooded 
mergansers, a pair of Common loons, two pair of Bufflehead, a lonely pied-billed female 
grebe, and hundreds of swirling tree swallows.  Gusty north winds made the south end of 
pond pretty rough and barren.
