Construction continues in and around the Nature Center at 
the park.  That plus cloudy skies and a stiff breeze made 
for a slower day overall, but I still managed 13 warbler 
species: NORTHERN PARULA, CHESTNUT-SIDED, BLACK-THROATED 
BLUE (many), YELLOW-RUMPED WARBLER (dwindling), 
BLACK-THROATED GREEN (also many), PRAIRIE (thanks to 
some other birders at the Yard), BLACKPOLL, 
BLACK-AND-WHITE (several), AMERICAN REDSTART, OVERBIRD, 
COMMON YELLOWTHROAT, and HOODED WARBLER (first of year for 
me).  Others reported Nashville and Yellow while I was 
there.

Also finally got my first WHITE-EYED VIREO of the season 
(heard only).  May have heard Acadian Flycatcher (once; 
did not repeat).  Full eBird report:
