Today was overall a bit less birdy, but there was some turnover of birds.  Four warbler species:

BLACKBURNIAN (singing male, continuing a good run for this species this spring)
Black-throated Green
Black-and-White (female, also may have heard a male singing)
Am. Redstart (singing first-year male)

Others:
Scarlet Tanager (2, male and female)
Cedar Waxwing (2, maybe more)
