Answer to Previous: This bird is not a Yellow-breasted Chat because the yellow on a chat stops before the legs further up near the breast. The answer is Blue-winged Warbler and not Prothonotary because of the wing patch (which is hard to discern from the background in this photo).

I think that this is a Song Sparrow, Southwest population. It does not have a yellow bill like a red Fox Sparrow would have, and it appears to have less rufous on the face.
I can’t decide between American Tree or Rufous-winged Sparrow, but am fairly sure it is one or the other.
OK, I’ve made up my mind- Rufous-winged Sparrow
Yeah, I think you might be right. The vent is yellowish, which is definitely a characteristic of Rufous-Winged. Also, it has more of an eye-ring than a southwest Song Sparrow should have. But this bird has a grey beak, and a Rufous-Winged Sparrow’s beak should be yellowish.
I say rufous-crowned sparrow because rufous cap and eye stripe gray back and white eye ring
I say a coastal rufous-crowned sparrow, not a rufous-winged, because of the grey bill, the white eye ring, the rufous cap, the rufous eye line, and the barely visible rufous and grey splotches on its mantle.
