[edit] Distribution

This smart-looking small gull is endemic to areas where it has access to the Humboldt Current off western South America: found in Ecuador, Peru and Chile.

[edit] Taxonomy

This is a monotypic species[1], which is sometimes placed in genus Larus.

[edit] Habitat

Rocky coasts for resting and feeding in the sea, but usually breeds far from the coast in flat desert areas filled with small rocks. A few recent reports of coastal breeding in a year with poor food availability.

[edit] Behaviour

[edit] Diet

Their diet consists mostly of mole crabs; also fish and offal.

[edit] Breeding

Colonial breeders. Nesting season is November to January. The adults stay with the chicks during the day, but one adult heads for the coast at night to forage.
