Why are female animals less colorful than males?

Sexual selection is responsible for many of the features unique to one sex in a given species. Darwin concluded that color differences between sexes in birds (also known as sexual dichromatism) result largely from female preference for bright colors in males.

Why are males more brightly colored than females?

Male animals are generally more colorful because they have to compete with other males to attract females. Bright colors can provide a “signal” to the females about the overall quality of a male and his genes.

Charles Darwin developed much of the theory that helps explain this.
