    Is that a clay-colored sparrow? The white breast and something in the stripes on the face suggest that, but I haven't seen one in person.

    I want to say that this is a grasshopper sparrow, though photographed at an angle that obscures the more classic head profile as a field mark.
    It does have a pale medial crown stripe. It doesn't have a throat stripe. And are those the barest hints of rufous at the shoulders?
