Occurrence Remarks The documentation form by Mike Dooley is the only one submitted and forms the basis of this record. Other observers include Bill Scheible, John Havilcek, Joyce Havilcek, and Jim Durbin. | Elimination of similar species: None eliminated on-site. Possible mis-identifications, given the premium conditions and extended period under which this bird was studied, might be as follows (consulting the National Geographic Society field guide): (1) fall adult Blackburnian Warbler: bird in question was strongly streaked on breast and sides, not just flanks; (2) female Townsend's Warbler: streaking on breast and sides of bird in question did not have semi-necklace effect of Townsend's; olive of head and back much grayer; (3) female Praire [sic] Warbler: bird in question had extended yellow post-occular stripe; streaked breast, not just sides and streaks bolder; had white belly; (4) fall Blackpoll Warbler: bird in question was much more boldly streaked on breast and sides; had extended post-occular yellow stripe, clearly defined cheek patch. All of above eliminated due to bird in question having wings similar to back color and not of a contrasting charcoal, as well as having a bold yellow-olive rump. All but Praire [sic] Warbler eliminated due to bird in question's virtual lack of wing bars. | The original documentation form event lasted from 13:45:00/15:00:00.

Event Remarks Viewing Conditions: Viewed from indoors through a picture window onto a feeding platform no more than nine or ten feet away. Bird was in bright afternoon winter sun when perched outside the covered feeding platform, a little more shaded when inside the feeding space (thought not enough to be a factor). Very long looks, both through binoculars and with the naked eye.
