Olrog, 1958Olrog's Gull (Larus atlanticus) is a species of gull found along the Atlantic coast of southern Brazil, Uruguay and northern Argentina. It was formerly considered a subspecies of the very similar L. belcheri. It is a medium-sized gull with a blackish mantle, white head and underparts, a black band in the otherwise white tail, and a yellow bill with a red and black tip. Non-breeding adults have a blackish head and a white eye-ring. The species is named after Swedish-Argentine biologist Claes C. Olrog.[1][2]
It is threatened by habitat loss. This bird eats small fish, crabs, and people's garbage.
