All the same individual bird, but you can see how the lighting conditions affect the perceived colors. I think this is a Swainson's? The tail was rusty, but didn't seem to contrast as sharply with the back as I usually see on Hermits. Then again, refer to my above comment on the lighting conditions.

Normalized to -3db

Black-headed Grosbeak or American Robin? (ignore the robins chipping in the background; the subject of this observation is whatever is making the differently-pitched chip call between its bouts of song)
