Introduction: The Phenomenon of Male Birds’ Bright Colors

One of the most striking features of many bird species is the difference in coloration between males and females. In many cases, male birds exhibit bright and flamboyant plumage, while females are more subdued and drab in color. This phenomenon has puzzled ornithologists for centuries, and has been the subject of much scientific investigation. Why are male birds prettier than females, and what purpose does their colorful plumage serve?

Historical Context: Early Observations of Male Bird Coloration

Dating back to ancient times, people have been fascinated by the beauty of birds, and have noticed the striking differences in coloration between males and females. The Greek philosopher Aristotle wrote about the colorful plumage of male peacocks, while the Roman naturalist Pliny the Elder described the brilliant colors of male birds of paradise. In the 19th century, Charles Darwin became interested in this phenomenon, and proposed his theory of sexual selection to explain why male birds have evolved to be so colorful.
