A large species of flamingo closely related to the Greater Flamingo and Chilean Flamingo. 120–140 cm (47–55 in) in length, the males weigh 2.8 kg (6.2 lb) and females 2.2 kg (4.9 lb) kg. 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 a restricted black tip, and the legs are entirely pink. The call is a goose-like honking.
It is the only flamingo which naturally inhabits North America. The American Flamingo breeds in the Galápagos, coastal Colombia, Venezuela and nearby islands, besides the Guyanas and Cape Orange in Brazil. It also breeds in the Yucatán Peninsula of Mexico, and in the northern Caribbean in the Bahamas, Hispaniola, Cuba and the Turks and Caicos Islands. Most sightings in southern Florida are usually considered to be escapees, although at least one bird banded as a chick in the Yucatán Peninsula has been sighted in Everglades National Park, and others may be wanderers from Cuba. From a distance, untrained eyes can also confuse the Roseate Spoonbill with it. Its preferred habitats are similar to that of its relatives: saline lagoons, mudflats, and shallow brackish coastal or inland lakes. An example specific habitat is in the Petenes mangroves ecoregion of the Yucatán.
It was formerly considered conspecific with the Greater Flamingo, but that treatment is now widely viewed (e.g. by the American and British Ornithologists' Unions) as incorrect due to a lack of evidence. It has also been known as the Caribbean Flamingo, but the species' presence in the Galápagos makes that name problematic. 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 of up to 6 years when they reach sexual maturity. Their life expectancy of 40 years is one of the longest in birds. I visited NYC in July this year. Spent an entire day at the Bronx Zoo, where I must say, the animals were happier than I've ever seen (for zoo animals), and for good reason- the enclosures were spectacular and well-maintained.
