Andean Gull

Chroicocephalus serranus

The Andean Gull (Chroicocephalus serranus) is a medium-sized gull found in the high Andes of South America, particularly in Peru, Chile, Bolivia, and Argentina. It has a white head and body, with a grey back and wings, and a distinctive black hood during the breeding season. This gull is well adapted to high-altitude lakes and marshes, where it feeds on small fish, insects, and scavenges for food. It is known for its striking aerial displays during courtship, with pairs engaging in synchronized flights and vocalizations. The Andean Gull is a resilient species, but it faces threats from habitat degradation and disturbance at its breeding sites.
