Structural Color

Look at the way the color changes with angle in this Resplendent Quetzal (Trogonidae: Pharomachrus mocinno) feather:

This is produced by structural color. Instead of pigment, the fine structure of the feather reflects certain wavelengths of light, producing a specific color that changes depending on the angle viewed. This effect is most obvious in hummingbird gorgets, but this is a pretty neat example too.

  1. Very neat example of structural color... you can't not love that bird.
