South Shetland Islands (probably = Falkland Islands).
Some authors place this species and other “hooded gulls” in genus Leucophaeus (see L. modestus). Has sometimes been combined with L. pacificus in genus Gabianus on basis of strongly hooked bill. Previously thought probably to be most closely related to L. belcheri and L. atlanticus, or to L. heermanni; speculated that its unique behaviour, plumage and chick pattern may advocate placement in a monospecific genus. Monotypic.
S South America from SC Chile (Chiloé I) and SC Argentina (Punta Tombo, in Chubut) to Tierra del Fuego; also Falkland Is. Outside breeding season, occurs slightly farther N on both mainland coasts.
