Observation details

[Kellen: A continuing individual, found here yesterday by Lucas and Mark Stephenson. We saw it not long after arriving, foraging at mid-level in the willows with a mixed group of passerine birds. I mostly noted that it was a very grayish vireo overall, but my views were fragmented and brief (though decent overall), so I never really had an extended opportunity to study the bird well. It was generally gray above and whitish below with a yellow wash on the flanks that was reminiscent of Warbling Vireo. I didn't get a good look at the head, but there seemed to be somewhat of a pale supercilium and dark eyeline pattern going on that appeared to be very muted. The bill was stout and pale, sort of grayish. The bird did not vocalize. I am not familiar with Bell's Vireo subspecies (and probably not even the whole species) but the Eastern group looks to be the emerging agreement. Based on the yellow wash to the flanks, that seems right.]
