Found originally by Jim Pawlicki, who had questions at first about this bird--i.e that it had some aspects of juvenile/first fall LUWA. Description: Tail -pumping warbler with faint yellowish wash on upper chest & flanks, slightly darker yellow on under tail coverts. Uniform darkish gray undertail feathers. Dove - gray above, including wings (no wing bars) , dirk-like small horn-colored bill, thin white eye-ring, though not as defined as in an adult VIWA. I did not get to see the upper tail coverts of this bird, both others in the group may have. Audubon's warbler-like chip, but maybe a little higher in pitch and drier. Jim Pawlicki was there to kindly confirm, discuss and help. [SES]
