Behavior: Flitting on the outer branches of a large willow in full view, at first being chased out of sight by a yellow-rumped warbler. On second sight, again foraging on the outside of a large willow and then disappearing inside.

Similar species and how
were they eliminated:
Graces warbler has yellow lores and supercilium, gray cheeck area and no white patch. I consulted my Sibley after the first sighting to make sure my first impression was correct, and when I saw the bird again 15 minutes later, I paid close attention to the patterns on the head and throat and was made certain that this was indeed a yellow-throated warbler.
Previous experience with
this & similar species:
I have seen the yellow-throated in Kentucky, and the Graces several times in southern Utah.
