Flamingos mate in pairs each year; however, these pairs can change from year to year. The male builds a nest with his female mate, and the female lays one egg each season. The male and female flamingos stay together after the egg hatches to care for their offspring.
When a flamingo is born, it has grey feathers and a pink beak. Flamingos become pink at about 2 years of age. Flamingos get their pink color from their diet, which consists of algae and shrimp containing the carotenoid pigment.Learn more about Birds
