Elden Spring: Mystery bird
Elden Spring had one good warbler flock near it this morning that included, 4 Nashville Warblers (it seems to be a banner year for this species), 3 Wilson's, 1 orange-crowned, 1 Black-throated Gray, 1 MacGillivray's, and this bird:




I am interested to hear opinions. This bird was terribly uncooperative and largely foraged within the juniper in the pics. In the field the bird had an eye-catching patterned face, giving me a first impression of Warbling Vireo. The greenish uppers and warbler bill ruled this out. The backside of the bird showed very clear white undertail coverts and left me wondering if this is a Tennessee Warbler?

Red-breasted nuthatch was the only other bird of note.

RE: Elden Spring: Mystery bird
Hi Jason,

I'm not speaking with any type of authority - I can remember seeing one Tennessee maybe 14 yrs ago, and it was quickly forgotten when another, flashier warbler stole the spot light. I'm mostly hoping my reply will prompt others to chime in. That being said, everything I can see about the bird seems to line up with tennessee since I can't think of anything else - the greenish back, lack of wingbars, grayish head, bill shape, pale underside, your description of the face pattern, and the white undertail coverts. Interesting bird!
