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).
In your answers to this photo quiz, don't forget to explain your logic, other people might like to learn from your line of reasoning.

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.
