I looked at the Chipping Sparrow, but in photo #3 it looks like this sparrow has a crest (white, yellow, or buff), which a Chipping Sparrow lacks). Of course, it may be just the way the light is playing off the bird's head, but I think it's meaningful.
Kaufman's field guide shows a (winter) color variation which looks similar. Without being able to download & zoom in it's a little hard to see for sure. Very few sparrows with the dark line going thru the eye.
