iridescent feathers

Rainbow-shifting bird coating

Iridescent feathers display shifting colors that change with the angle of light or viewing—the shimmering greens and purples of a peacock's tail, the throat patch of a hummingbird.

The effect comes from microscopic structures in the feather that refract light rather than from pigment.

The grackle's iridescent feathers gleamed in the sun.
