Iceland Gull vs Short-billed Gull

Iceland Gull

Larus glaucoides

Large693 gCoastal

The Iceland gull is a medium-sized gull, although relatively slender and light in weight. In length, it can measure from 50 to 64 cm (20 to 25 in), wingspan is from 115 to 150 cm (45 to 59 in), and weight is from 480 to 1,100 g (1.06 to 2.43 lb). Among standard measurements, the wing chord is 37.9 to 44.3 cm (14.9 to 17.4 in), the bill is 3.6 to 5.4 cm (1.4 to 2.1 in), and the tarsus is 4.9 to 6.7 cm (1.9 to 2.6 in). It is smaller and thinner-billed than the very large glaucous gull, and is usually smaller than the herring gull. It takes four years to reach maturity. Voice: The call is a "laughing" cry like the herring gull, but higher pitched.

Short-billed Gull

Larus brachyrhynchus

The short-billed gull has a length 40–45 cm (16–18 in) and a wingspan 100–120 cm (39–47 in). It is smaller than other gulls in the Common gull complex, with a shorter bill and longer wings. Its wings appear long and narrow in flight relative to its short body. In breeding plumage, adults have a white head, pale eyes surrounded by a red orbital skin, yellow legs and bill with no markings. In winter, the head is marked with brown mottling, the eye orbital skin becomes grayish and the bill becomes duller with a faint dark marking.
