Jeff --
I would lean towards two Buntings. The first bird structurally looks like a bunting, but the wing is a bit tricky.
I think that first bird would have more color up in the shoulder (and maybe the wings generally) if it were a Grosbeak. There would be some structural differences in appearance also.
Also note the rest of the similarities in structure between your two birds, excepting the wing pattern.
That's my thought.
