Gray head, sharp bill, obvious white eyebrow, dark line through eye (no broken eye-ring), dark greenish back and tail. Throat and breast plain pale white (no streaking or yellow). Undertail coverts were white.
Song or call & method of delivery: none
Behavior: Foraging high in tree in clumps of leaves. Was only visible for short periods as it moved from clump to clump. From our position the tree was backlit, but the bird moved several times in front of leaves for us to see the details. Compared to nearby Yellow-rumped Warblers, the Tennessee's foraging was slow and thorough.
Habitat: Riparian, mix of trees along canal.
Similar species and how
were they eliminated:
Not a vireo because the bill was small, thin and sharp.
Orange-crowned Warbler has split eye-ring, no obvious supercilium, streaking on breast, yellow undertail coverts, lighter-colored back. yellowish tinged head, throat and breast(none of which our bird had).
