Distinctive, but rather local and uncommon in Chile (more common in Argentina and elsewhere) in grassy wetlands, reedy marshes, and on lakes. Associates with other waterfowl, but usually is not out on open water and is easily overlooked. Readily identified by small size, dark cap, pale cheeks, and blue bill with yellow patch at base. Range does not overlap with the larger and more boldly patterned Puna Teal.
