Rather local and declining; found at salt lakes and bogs in the high Andes. Associates readily with Chilean and James’s Flamingos, although each species often stays slightly apart within mixed groups. All plumages show clean-cut black triangle on closed wings, unlike other flamingos. Adult has long bill “hook” and diagnostic yellow legs. Like other flamingos, immature often noticeably smaller than adult, but has long bill “hook”, unlike the stubby bill of smaller and shorter-legged James’s Flamingo.
