A Mourning warbler's still flying around the weeds in front of the 
maintenance yard tangle and sang invisibly at least once from the low 
branches in front of the tuliptree to the right of those weeds before 
putting in a brief second appearance (I missed the first) among them.

Today's male Cape May sang a Bay-breasted-like fast trill from the ridge 
before being relocated in the maintenance yard parking lot a half hour 
later.  I heard him there another 15 minutes after that before he flew 
toward the nature center.

Here are the rest of today's RCP warblers, skipping over thrushes, vireos 
(all red-eyed), tanagers, and orioles.  The olive-sided flycatcher was not 
apparent, nor were Empidonax other than Acadian flycatchers.

American Redstart, Northern Parula, apparently no Black-and-white.

Blackburnian (on ridge seen by others), Bay-breasted (seen in maintenance 
yard by others and just across from my car in the nature center lot by me 
as I was giving up on them), Yellow-rumped still, Magnolia, Black-throated 
green (heard), Black-throated blue (heard, maybe seen), Blackpoll (now 
ubiquitous).

Tennessee (seen by others on ridge).

Canada (seen by others on ridge, heard in woods to maintenance yard and 
around nature center lot), Hooded (heard by others near equitation field).

Ovenbird (heard everywhere), Common yellowthroat (who never enjoyed so 
much attention before hosting a mourning warbler in their weed patch).
