| Caption | The wings of a Boat-tailed Grackle (Quiscalus major) shimmer in iridescent hues of blue, violet, and teal. The grackle's flashy plumage is an example of structural coloration - color that arises, not from the absorption of light by pigments, but rather from the interaction between light and nanoscale structures, resulting in diffraction, scattering, and interference. This grackle was perched in a willow tree in Paynes Prairie Preserve State Park, near Gainesville, Florida. | |
