Greenish back, two white wing bars, Oval yellow face with yellow seperated by dark area through eye and broadening behind eye. Mostly white underside with yellow breast and yellow continuing down side with dark streaking that seemed faint - perhaps due to distance.

 

On December 3, 2009, in this woodlot, I observed briefly- less than 1 second with a clear view- a warbler that I thought could be a Townsend\'s if my impression of what I saw was correct. It was moving with a feeding group of the same composition as the one of Dec 29. I observed it from about 15 ft at eye level getting only a side view. From that angle, I could see only black, yellow, and white. The head above the yellow face appeared very dark. I did not notice the broad ear patch area. The black line through the eye seemed more narrow, but I did not have time to really focus in on that feature. The black throat continued down the side as prominent black streaking through the yellow on the side. The lower belly and undertial area was white.
I have not yet seen any of the video or stills taken on Dec 29, not even my own brief video. My visual impression on Dec 29 was of a bird with much less black than on Dec 3. Distance and angle of view may be responsible for the difference.
