This is an eastern warbler, not a bird that I was expecting.  I did see one previously at the swamp in the Fall of 2014, but this is quite an unusual bird.  They are very uncommon but not exceptionally rare along the coast in fall and winter.

This species superficially resembles the common western migrant, the Black-throated Gray Warbler.
