The species is abundant and widely distributed; it faces no significant short-term risk.
The Andean gull is a high-mountain gull that breeds on the lagoons of the high Andean puna, far from any sea. In the breeding season it has a black hood and a red eye-ring. It descends partly to the Pacific coast in winter, but many populations stay at altitude all year, on lagoons that freeze overnight.
