Andean Flamingo

The Andean Flamingo (Phoenicoparrus andinus) is a species of flamingo native to the Andes mountains of South America. It is closely related to James's flamingo. The Chilean flamingo Andean flamingo, and James' flamingo are all sympatric, and all live in colonies (including nesting areas). 
Description
It is the largest flamingo in the Andes and is one of the two heaviest living flamingos alongside the taller greater flamingo.
The flamingo has a pale pink body with brighter upperparts, deep pink lower neck, breast, and wing coverts. It is the only flamingo species with yellow legs and three-toed feet.
Behavior
Feeding
These flamingos are feeders and their diet ranges over the entire spectrum of available foods, from fish to invertebrates, from vascular plants to microscopic algae.
Vocalizations
Very poorly known; the available recordings fall into three call types. Peep a surprisingly high-pitched, short, clear note that sounds rather Passerine-like. Most often given in a quick series that slightly descends, but sometimes also singly. Quack a rough quack or honk-like note that can be given individually or in series. Lower-pitched and shorter in duration than the analogous call in Chilean Flamingo, but higher-pitched than in James's Flamingo. Often heard in flight. Chuckle a quiet call made up of short, low-pitched quack-like notes. Lower-pitched and less nasal than the Quack call, and typically given in a faster series.
