A little addendum...The Dog Run at Rock Creek had 2 singing Canadas and a Redstart, and there were also Blackpoll in quite a few areas round the park.  But a quiet morning, as Gail noted, saved only by the Olive-sided.  Obviously a lot of stuff moved on from there last night.

  Hi --

Otherwise, VERY slow -- both in the Yard and at the Ridge -- just a handful of warblers at the Maintenance Yard and Nature Center, which included Canada, Black-throated Blue, Ovenbird (heard), Nashville, Chestnut-sided and Yellowthroat.

Thrushes were in evidence, with both Veery and Swainson's but no Gray-cheeked yet(?) Lots of Red-eyed Vireos.
