The kelp gull ("Larus dominicanus"), also known as the Dominican gull, is a gull that breeds on coasts and islands through much of the Southern Hemisphere. The nominate "L. d. dominicanus" is the subspecies found around South America, parts of Australia (where it overlaps with the Pacific gull), and New Zealand (where it is known as the black-backed gull, the southern black-backed gull, mollyhawk – particularly the juveniles, or by its Māori name karoro). "L. d. vetula" (known as the Cape gull) is a subspecies occurring around Southern Africa.
