Chipping Sparrow (Four Photographs) and some comments on Processing

I believe this to be a chipping sparrow. When I looked at the raw files of this bird three things stood out: part of its throat and some of it white feathers were bluish; there was Moire´ in the feather pattern, and the lighting on the face of the bird was not consistent. For the first, a hue saturation adjustment in Photoshop worked well, for the second, some selective sharpening helped and for the third, the radial filter in Lightroom worked nicely. I was fortunate that my exposure and the dynamic range of the original raw file had the latitude I needed. I am beginning to think there is no such thing as bad light. (See comments below, I am told this is an American Tree Sparrow).
