Phoenicopterus roseus
Unmistakable, except in areas where other Flamingo species occur. Differs from Lesser Flamingo by greater size, paler and less red plumage, pink (not deep red) bill, and more contrasting coverts. From Chilean Flamingo by less black on bill, and pink legs without contrasting joints. Immature birds first brown with white belly. Later dirty white with coverts tipped black.
Nasal, di-syllabic, gooselike honking. Sometimes pure and high-pitched, other times deep and with peculiar, raspy, frog-like quality.
