Description of the Bird
Small overall and slender gray bird. First observation was it's lighter colored throat in comparison to its back and wings. I want to say that the face seemed mottled with white and gray patches. Overall, though, was this was a very pale gray bird. Final confirmation was the brown rump patch visible when it flitted between trees. I was never able to view a crown patch. Shape was definitely that of a warbler and never once thought of it being a vireo or other bird. No eye ring or eyebrow excluded Warbling Vireo and Gray Vireo. No apparent wing bars.
Behaviors: Yellow Jacket Canyon is a heavily wooded riparian area of Cottonwoods and Tamarask. There were many Yellow-rumped Warblers all calling along this whole stretch of woods, almost became a background sound. At one point I heard a distinctly different "chink" come from a bush right next to me, and out flew a small gray bird. It flew up into a cottonwood where it continued calling (never stopping to sing) as it fed. It never stopped and rapidly flitted from branch to branch while feeding. It favored the lower branches of the canapy the entire time observed, never being in the higher portions of the cottonwoods. For ten minutes I followed this bird from tree to tree downstream trying for a photo, but was not successful. It never stopped moving enough for me to catch up with it in the camera viewfinder. At one point it finally flew to another cottonwood and abrubtly stopped calling. I was not able to relocate. During the ten minutes, I was able to see it's rump patch several times.
Call: Calling was a very sharp "chink" in comparison to all the Yellow Warblers present and their "chips"
