Good day to be at the Maintenance Yard, with a nice variety 
of warblers giving close-up looks for a number of birders: 
NORTHERN PARULA (female), MAGNOLIA (male, great looks), 
BLACK-THROATED BLUE (M&F), YELLOW-RUMPED, BLACK-THROATED 
GREEN (superb), BLACKPOLL, BLACK-AND-WHITE (F), AMERICAN 
REDSTART (F), OVENBIRD (heard only at the Yard; I saw one in 
the forest), COMMON YELLOWTHROAT (M&F), and CANADA WARBLER 
(singing and posing for us).  Others saw Blackburnian (M&F) 
and Chestnut-sided (heard only).  Also of note, many 
SWAINSON'S THRUSHES around, plus GRAY-CHEEKED THRUSH, and a 
LINCOLN'S SPARROW and SWAMP SPARROW at the Yard.  Heard a 
BARRED OWL from the Yard as well, and ACADIAN FLYCATCHER is 
back in the forest just down from the stables.

Off to Vancouver, Canada for a week tomorrow.  Someone else 
can take over posting for the park. :)

Location:     Rock Creek Park
Observation date:     5/21/07
Time:	06h00-09h45

Notes:  Probably my last visit to the park before heading to 
Vancouver for a week.  Started out mostly cloudy and calm 
(so I went to the Yard), but then sunny and breezy.  Lots of 
good looks at warblers around the dead vines at the Yard, 
plus Lincoln's Sparrow, kingbird, and another Gray-cheeked. 
A couple of mystery warblers, probably females (one likely 
Blackpoll).  Others reported Blackburnian (male and female) 
and Chestnut-sided.  The Acadian Flycatcher is back in its 
usual spot in the forest just down from the barn.  Also 
heard my first Barred Owl in a while at the park.  Deer and 
chipmunks also seen.
