Took a walk with a birding friend this afternoon on the River Trail above
Great Falls.  On the Potomac, a short ways up, just opposite Riverbend Park
in Fairfax County,Va.,we saw our first-of-the-season Bufflehead ducks; there
were about fifteen total, mostly males. Soon there should be many more
individulas and species on the river.
