This looks like a Western.

One thing I learned from reviewing the identified/photographed Cassin's Kingbird a few months ago at Jordan Lake Dam -- Cassin's vs. Western -- is that on Cassin's, there is no darker face-mask appearance behind the eye. That is, the slate gray of the crown, nape, and cheek etc., is concolored on most or all Cassin's On most Westerns, there is a clear blackish face mask that extends onto the cheeks, a bit behind the eye. Thus, on a Western, the crown and nape are a tad softer or paler gray -- to medium-gray, but typically lighter than the cheek area.
> The white on the malar area -- side of the throat -- can be difficult to use. Westerns can show this. And, normally, you cannot see the white outer tail feathers on a perched Western Kingbird. Cassin's can have a pale gray tip to the tail, but this can also be hard to see.
> My thought on this bird -- and I saved the first and last ones to my computer so I could blow them up -- is that I see a blackish cheek area -- like a mask, that seems to extend beyond the eye -- a bit shrike-like. That -- and the not sharply-defined white throat when seen from the front (4th photo when blown up) -- leads me to believe this is, indeed, a Western Kingbird. Some of us have been fooled by a few previous iffy yellow-bellied kingbirds photographed by others and posted on eBird lists that we were hoping could be, or might be, Cassin's; the majority in such cases strongly supported Westerns. I should note here that the Jordan Dam bird on the photographs show a concolor head area -- crown, cheek, and nape, consistent with a Cassin's.

While it was reported as a western, I was wondering if it may have some characteristics of Cassins??? The images are distant and when I blow them up, I can’t definitively make out white stripes on the outer tail. The malar area in some seems to contrast quite a bit with the surrounding area as well. Thoughts???
