Habitat

Habitat in Breeding Range

The breeding sites, first discovered in the 1970s, are barren, mostly flat, montane deserts, which lack vegetation but have big rocks that provide shade for the chicks when the parents leave the nest in search of food (31, 19, 20).

A coastal breeding event was exceptionally recorded in northern Chile during a developing El Niño event (17, 19), but this colony no longer exists (20).

Habitat in Nonbreeding Range

Gray Gull feeds along sandy coastal beaches and offshore, within the Humboldt Current, often feeding with flocks of other seabirds.
