The American flamingo is a large species of flamingo closely related to the greater flamingo and Chilean flamingo. It has also been known as the Caribbean flamingo.
This flamingo lives on the coast, salt marshes and lagoons in the islands of the Bahamas, Cuba, Haiti and the Dominican Republic and the Galapagos, as well as in Central America and the north of South America.
It is the only flamingo which naturally inhabits North America.
It differs from the common and Chilean flamingos in that it has bright red plumage.
Although its numbers are still quite large -there are about 80-90.000 remaining- they are gradually decreasing due to the constant destruction of their environment (like many other species).
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).
