Although I'm still counting (not dusk yet!!), I thought I'd 
submit this report now of what I've seen today in our yard 
in West Laurel (PG County).  The highlight was yard bird 
#105: a first-year female CHESTNUT-SIDED WARBLER.  Overall a 
*lot* of variety for us, including a big kettle of 
BROAD-WINGED HAWKS (at least 115 individuals), an adult BALD 
EAGLE, 3 more warbler species: MAGNOLIA, YELLOW-RUMPED, and 
BLACK-AND-WHITE (our first fall warblers in the yard BTW), 
and a female ROSE-BREASTED GROSBEAK.  Conspicuously missing 
(so far) are Ruby-throated Hummingbird and Hairy Woodpecker.
