Quick Answer
Iridescence is a shiny color effect that changes with viewing angle. In birds, it is caused by microscopic feather structures, not pigments alone.
The Full Story
Iridescence in bird feathers happens when light reflects from tiny structures in the feathers and interferes in ways that change color with angle. This is why feathers can look green, blue, purple, or bronze and seem to shimmer as the bird moves. Hummingbirds, peacocks, starlings, and many ducks are famous for iridescent plumage. The effect can help with display, mate attraction, and species recognition.
