Wikipedia Abstract

The Andean gull (Chroicocephalus serranus) is a species of gull in the Laridae family. As is the case with many gulls, it has traditionally been placed in the genus Larus.It is found in the Andes in mountainous regions of Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. It is unusual for a gull in that it breeds inland in mountain areas. It may be variously found around rivers, freshwater lakes, saline marshes, and pastureland.
