A Rainbow of Colors

The male Rufous Hummingbird is capable of displaying a rainbow of colors.  His normal pose may be seen as rather drab, as shown in the above photo, but is an instant he can flash additional brilliant colors, as shown in the lower two photos. 

These photos are of the same bird within a one minute time frame from 6:29 to 6:30 last evening. I think the reason for such a dramatic display is that his territory at the feeder was being challenged by a second male Rufous Hummingbird.
