Hey Moose, what can you tell me about the changing color of the neck and head feathers of the adult male Anna's? They
can change from dark, almost black to bright red from one frame to the next when shooting 3 frames per second bursts.
Fascinating
It's because the color is not from simple reflection from a colored surface, but by iridescence from the structure of
the feathers. <http://en.wikipedia.org/wiki/Iridescence>
The slightest movement of the head may change the color.
