The Chilean Flamingo is a large species closely related to Caribbean Flamingo and Greater Flamingo, with which it was sometimes considered conspecific. it is 125cm long.
It breeds in temperate South America from Ecuador and Peru to Chile and Argentina and east to Brazil; it has been introduced into Germany and the Netherlands. Like all flamingos it lays a single chalky white egg on a mud mound.
The plumage is pinker than the slightly larger Greater Flamingo, but less so than Caribbean Flamingo. It can be differentiated from these species by its greyish legs with pink knees, and also by the larger amount of black on the bill. Young chicks may have no sign of pink coloring whatsoever, but instead remain grey.
