Grey Gull

Leucophaeus modestus

Medium380 gDesert

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).

Laughing Gull

Leucophaeus atricilla

307 gMarine

This species is 36–41 cm (14–16 in) long with a 98–110 cm (39–43 in) wingspan and a weight range of 203–371 grams (7.2–13.1 oz). The summer adult's body is white apart from the dark grey back and wings and black head. Its wings are much darker grey than all other gulls of similar size except the smaller Franklin's gull, and they have black tips without the white crescent shown by Franklin's. The beak is long and red. The black hood is mostly lost in winter. Laughing gulls take three years to reach adult plumage.
