The term peacock is sometimes used to refer to both males and females. Strictly speaking, peacock refers to the male, and it does not lay eggs. The female or peahen lays three to five eggs at a time.

Peacocks are large, colorful birds with long tail feathers that can be spread out in a fan. Peacocks show off their beautiful tails during courtship to entice the females. Females choose their mates based on size, color and the beauty of the tail feathers. There are three species of peacocks: the blue peacock, the green peacock and the Congo peacock. The blue peacock is found in India and Sri Lanka. The green peacock lives in Java and Myanmar, while the Congo peacock is seen in African rain forests.
