Like all flamingos, it lays a single chalky-white egg on a mud mound, between May and August incubation until hatching takes from 28 to 32 days both parents brood the young for a period up to 6 years when they reach sexual maturity. Their life expectancy of 40 years is one of the longest in birds. Adult American flamingos are smaller on average than greater flamingos, but are the largest flamingos in the Americas. They measure from 120 to 145 cm (47 to 57 in) tall. The males weigh an average of 2.8 kg (6.2 lb), while females average 2.2 kg (4.9 lb). Most of its plumage is pink, giving rise to its earlier name of rosy flamingo and differentiating adults from the much paler greater flamingo. The wing coverts are red, and the primary and secondary flight feathers are black. The bill is pink and white with an extensive black tip. The legs are entirely pink. The call is a goose-like honking. Learn more about Greater Flamingo
