Default Interesting Hummingbird Behavior

It appears that the male Ruby-throated Hummingbird has the same ability as the Red-winged blackbird has in that it can control how much red he can show. Take a look at this series of photos I shot today, all within seconds of each other.

Hi Gary, what you see is simply the bird shifting position, and the light striking the feather from a different angle.

"Hummingbird Color
No other bird possesses such a wide spectrum of breathtaking colors as the hummingbird. This is due to the structure of the feathers. While most birds can attribute their color to pigmentation, the hummingbird's shimmering color is structural rather than pigmented in origin. The iridescent colors of the feathers arise from layers of special cells within the top layers of the feathers. Light that hits these cells is broken apart; some wavelengths are reinforced and intensified, while others are nullified through interference. The resulting colors are amazingly vivid, but, unlike pigmented colors, can be seen only when the light is hitting the feathers at precisely the right angle. Thus, a hummingbird can shift its position just a little, and what was once black will become blazing red."

Whatever the description for what it is, the color changing from image to image is very cool. Nice shots, Gary!

Great series. As much as I like trying to shot the little guys I have to admit the really are kinda ugly and scruffy looking.
