I'm having a bit of a problem narrowing down what type of kingbird this is.

Both Western and Cassin's Kingbirds are native to my Southern New Mexico area; but they're both supposed to have a more dull yellow belly.

As for the Couch's Kingbird, which does have a bright yellow belly, its range isn't supposed to extend this far north or west; and it isn't supposed to have any white tail feathers.

I'm hoping that one of you bird experts can tell me for sure what this one is.
