The pink or reddish color of flamingos comes from carotenoids in their diet of animal and plant plankton. American flamingos are a brighter red color because of the beta carotene availability in their food while the lesser flamingos are a paler pink due to ingesting a smaller amount of this pigment.
The largest male flamingos have been recorded to be up to 187 cm (74 in) tall and to weigh 4.5 kg (9.9 lb). [6] Most of the plumage is pinkish-white, but the wing coverts are red and the primary and secondary flight feathers are black. The bill is pink with a restricted black tip, and the legs are entirely pink. The call is a goose-like honking.
