Hi all --

The frontal passage brought out a few birders and also, a few birds, to Rock
Creek Park DC. Diversity was pretty good, just numbers being low. Wallace
Kornack and Jim Lemert started at the Ridge and Equitation Field, while
Barry and I went directly to the Maintenance Yard. Stephanie (the grad
student who is doing the cell-tower survey) worked the area around in cell
phone tower and into the woods on her regular transect. All of us saw
migrants and the mix was different -- in total 10 species of warbler and
several other migrants were observed -- highlighted by a first-year MOURNING
WARBLER foraging in a tangle of vines in a large clump of Devil's Walking
Stick off Military Rd, seen by Barry and me. Quite a surprise! We also had
another YELLOW-BELLIED FLYCATCHER, this an worn adult still showing its
yellow throat, gray upper breast wash and pale yellow lower breast and
belly, with a prominent yellow eye ring.
