Definition of iridescence
1 : a lustrous rainbowlike play of color caused by differential refraction of light waves (as from an oil slick, soap bubble, or fish scales) that tends to change as the angle of view changes... (this may also apply to birds :) , in fact it does .. same bird top and bottom, but moments in time and angle difference.
