Occurrence Remarks |
The documentation form with an addendum by Ann Johnson is the only one submitted and forms the basis of this record. | Elimination of similar species: Palm Warbler - no streaking on breast; chestnut cap not evident; streaking was black; breeding plumage unlikely on this date Pine Warbler - belly and undertail coverts bright yellow; wingbars not as distinct as the wing was not as dark nor the bars as white: streaking on the sides darker than a pine [...] Magnolia Warbler - Magnolia's body and wings too dark; adult eliminated because of no streaking on breast (only sides) and no black facial mask; immature does not have heavy enough streaking nor yellow extending up the face and around the eye far enough and the wingbars are too contrasting (black and white) Cape May Warbler - vibrant yellow undertail coverts would seem to by and large eliminate the Cape May, especially when combined with no streaking on the breast and belly; wing bars were two distinct pale yellowish markings, not white or blotched together Blackburnian Warbler - unstreaked back; no distinct cheek patch; no white wing bars on dark wings Blackpoll/Bay-breasted Warbler - unstreaked back; primary identification of fall blackpoll is white undertail coverts which eliminates this bird immediately. Also this complex normally has more distinct white wing bars on darker wings and the streaking on the sides is not the stark black on brilliant yellow but a more muted yellowish wash. | The original documentation form event lasted from 18:45:00/18:45:00. |

Event Remarks |
Viewing Conditions: Bird was high in 40' elm so at 20' (paced) light against the sky wasn't particularly good with naked eye. Even looking SE against a SW sun, the resolution of my 7x26 Bushnell binoculars alleviated the lighting problem. |
