Andean Gull

Least Concern

Spotted something wrong?

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.

Fun facts

  • It breeds above 4,000 metres, on puna lagoons that freeze overnight: it is one of the highest-living gulls on the planet.
  • Many populations never see the sea: they feed on invertebrates from the high-altitude bogs and on Andean cropland, and only some descend to the Peruvian and Chilean coast in winter.
  • It shares the puna lagoons with the Andean flamingos and the giant coot, an assemblage of high-altitude waterbirds found nowhere else in the world.
