Detailed description of bird: A obvious Warbler. The sides of the head were yellow with a olive gray smudge in the auricular area. The crown, nape and the back were olive brown. The wings were dark with two white wing bars. The throat was white. The underparts were buffy white with a stronger buffy wash to the side and flanks. The undertail coverts were white. I didn't see the tail well.
Song or call & method of delivery:  
Behavior: Feeding in the lower part of a willow tree toward the ends of the branches.
Habitat: Riparion corridor with willows,cottonwoods and a thick understory.
Similar species and how
were they eliminated:
Elimination: Lack of yellow on the breast,streaking on the sides and the back color ruled out a hybrid with Townsend. A first year female Black-throated green would also look more like a Townsend X Hermit hybrid then a pure Hermit.
Previous experience with
this & similar species:
Living on the West coast I've saw a lot of immature Hermit Warblers. I've also seen a few Townsend X Hermit hybrids.
