Why Are Birds So Colorful
The Science of Bird Colors Bird coloration arises from two primary mechanisms: pigments and structural colors. Pigments are chemical compounds within feathers that absorb certain wavelengths of light and reflect others, determining the color we perceive. Pigments produce color by absorbing specific wavelengths and are one of the two ways birds get to be so vividly colorful, the other being the physical structure of the feather.
For Dr. Shultz, most birds that appear green to you and me are actually a combination of blue feather structure and yellow pigment. Not so with the verdant turaco.
