On the way to work this morning I spied (while Lisa drove) a flock of about 20 to 25 geese heading north.  The lead 6 or so appeared to be white Snow Geese, with white bodies and black primaries and secondaries.  The rest of the flock was pretty dark.  As I did not have binoculars with me, that is all I can say.  

Currently over Bethesda, small groups of Ring-billed Gulls are heading north.
