Field Marks and Identifying Characteristics: |
First noticed a warbler making an unfamiliar chip, found the warbler high in
elms above me. Overall very drab, buffy yellowish on the back, head, throat and
breast, 2 white wingbars on dusky wings, faint streaking on flanks, faint eye
arcs and supercilium, dusky eyeline, white undertail coverts. Legs and feet
appear mostly yellowish. As we were watching the birds disusing ID possibility,
Cameron Cox showed up and promptly settle the ID as a Blackpoll, he has
extensive experience with this species and similar warblers, I have little with
this eastern complex. (see photos) |
