Similar species and how
were they eliminated:
Cassin's Vireo. Cassin's vireo is at its brightest at this time in fall but this bird was exceptionally bright. Not as bright flanks or back color on CAVI. Contrasting Yellow-green back consistent with BHVI where CAVI usually not as contrasting (head and back blend together)
Plumbeus vireo. PLVI displays plain gray plumage, not as contrasty as either CAVI or BHVI.
Previous experience with
this & similar species:
I have seen Blue Headed Vireo in Texas, New Hampshire and Maine.

I have seen Cassin's vireos in the west in New Mexico, Texas, Arizona and Utah. I have seen bright Cassin's vireo in fall including in the hand while banding in New Mexico, as well as

I have seen lots of plumbeous vireo throughout the west. I have only seen the very plain gray individuals not the brighter central american individuals.

Additional comments: Notes taken from ebird checklist (https://ebird.org/checklist/S273176374) submitted after sighting. Mckay Olsen made original ID. Initially we dismissed the bird as an extremely bright CAVI but after reviewing photos BHVI seemed to be more consistent with the feild marks and extremely bright coloration.
