Went to Blue Mash this morning hoping to find the OC Warbler reported
yesterday, but instead found a late Tennessee Warbler (white undertail
coverts, very faint wingbars), a "November Bird" for me, and the
latest Maryland eBird record (though Yellow Book indicates later
sightings).  Migration was supposed to have been heavy last night, and
there were good numbers of sparrows, including 5 Fox (FOS), and good
numbers of White-crowneds and Savannahs.

Good birding!
