The Grey Gull is a medium sized gull found along the west coast of South America. They are dark grey and during breeding their head is white. Their legs and bill are black and the iris is brown. Juveniles are brown with paler brown on the undersides and parts of the head.

:Diet:

They mainly eat mole crabs and some fish. They will also scavenge at fishing boats and fish plants.

:Courtship: No information on courtship but the Grey Gull has an unusual breeding ground for gulls. They breed in the Atacama Desert in northern Chile which has almost no rainfall during the year. This probably limits the number of predators.

:Nesting: Nests colonially. The nest is a scrape in the sand. While one adult attends the nest, the other flies to the coast for food to feed the chicks.

:Habitat and Range: The Gray Gull is the most common gull along the South American Pacific coast from Ecuador to Chile.

:Plumage/Molt No alternate plumage.

:Migration: Not a true migrant, but daily movement between the nesting site and the coast.

:Tongue/feet: The feet and legs are black.
