The giant coot is a species of bird in subfamily Rallinae of family Rallidae, the rails, gallinules, and coots. It is found in Argentina, Bolivia, Chile, and Peru.
Region
Andes Mountains
Typical Environment
Occurs on the Altiplano’s high-elevation lakes and marshes in Peru, Bolivia, northern Chile, and northwestern Argentina. It favors shallow, often semi-saline or brackish lakes with extensive emergent vegetation such as reeds and sedges. Pairs defend territories along gently sloping shorelines and protected bays. Nest mounds are placed in shallow water, sometimes forming conspicuous islands. They typically remain near reliable water bodies year-round, shifting locally as water levels change.
Altitude Range
3500–4800 m
Climate Zone
Highland
Ease of Keeping
Beginner friendly: 1/5
The giant coot is the largest coot, inhabiting high Andean lakes where pairs build colossal mound nests anchored with stones and vegetation. Adults are heavy-bodied and are reluctant fliers, often running across the water before becoming briefly airborne. They are strongly territorial around their nest mounds. The species is native to the Altiplano of Peru, Bolivia, Chile, and northwestern Argentina.
Temperament
solitary and territorial

reluctant flier with short rapid wingbeats after a running takeoff
Social Behavior
Usually found in pairs that maintain and defend territories, especially around their large nest mounds. Monogamous pairs cooperate to build and maintain nests using vegetation and stones. Nests and territories are reused and augmented across seasons when water levels permit.
