The Kelp Gull, known scientifically as Larus dominicanus, is a robust seabird with a commanding presence along the coasts and islands of the Southern Hemisphere. This species exhibits a striking contrast between its black upper parts and wings, and the pure white of its head, underparts, and tail. The wingtips are adorned with small white "mirrors," adding a touch of elegance to its flight. Adult Kelp Gulls have a yellow bill marked with a red spot and legs of a greenish-yellow hue, which become more vivid during the breeding season.
To identify the Kelp Gull, look for its size, which is intermediate between the lesser and great black-backed gulls of the northern Atlantic. Adults typically measure 54 to 65 cm in length, with a wingspan of 128 to 142 cm. The bill and tarsus measurements are also distinctive, with the bill ranging from 4.4 to 5.9 cm and the tarsus from 5.3 to 7.5 cm. Juveniles can be recognized by their black bill, grey-brown plumage with whitish edges, and a dark band in the tail. They mature over three to four years, gradually acquiring the adult's pale bill base and predominantly white head and underparts.
