The pink flamingos breed in large colonies that can gather up 200 000 monogamous couples during a breeding season (they change partners from one year to another). Males and females practice the nuptial parade: walking by groups, turn their heads, open suddenly their wings, feint grooming... A couple stays together during the whole breeding season. The nest is built, preferably on an islet which makes them safe from predators, with the substrate thereof (mud, silt, little stones...). The female lays a single egg (very rarely two eggs) which will be incubated by both partners for 29 days. The chick spends his first days in the nest, but join quickly the other chicks who stay together. Adults come regularly feed their babies. A chick is white and grey, and becomes pink between 2 and 4 years. They can fly around 80 days old.
