Holy cow. I'm holding a very blue, Bluejay's tail feather in my hand. I can make it go from blue to brown and back to blue again simply by changing the angle between it, me, and the light coming through the window. Great example of how the play of light and structure of the feather combines to produce the blue color in the bird. Who needs pigment when you've got sunshine!!!??!! (Smile). Incredible. Sar
