Description
The sexes are similar in grey gulls. Adults grow to a length of about 45 cm (18 in) and weigh some 360 to 400 g (13 to 14 oz). The head is white in summer but brownish-grey in winter. The body and wings are grey with the dorsal surface rather darker than the ventral region. The flight feathers are black and the inner primaries and the secondaries have white tips, visible in flight. The tail has a band of black with a white trailing edge. The legs and beak are black and the iris is brown. The call is similar to that of the laughing gull (Leucophaeus atricilla).

Feeding Habits
Grey Gull primarily feeds on mole crabs, supplemented by fish, nereid worms, and offal. Grey Gull forages along the shore, exhibiting a preference for intertidal prey, often captured via a unique run-and-grab technique.
Habitat
Grey Gull is commonly found in barren montane deserts with scarce vegetation and little to no fresh water. This species is also associated with sandy coastal beaches, where it often feeds and may join mixed feeding flocks with other seabirds over the nutrient-rich waters of the Humboldt Current. Grey Gull's typical breeding sites are located in desolate inland montane areas, however, occasional coastal breeding activity has been noted, particularly during environmental anomalies such as El Niño events.
