DISTRIBUTION, POPULATION-SIZE AND CONSERVATION OF HARTLAUBS GULL LARUS-HARTLAUBII

Hartlaub’s Gull Larus hartlaubii is endemic to southern Africa, where it breeds between Swakopmund, Namibia and Dyer Island, southwestern Cape Province, South Africa. The species has been re breeding at 48 localities within this range. Between 1984 and 1989 an estimated 12000 pairs bred at 31 localities. Twenty-eight percent of the population breeds at Robben Island off the Cape Peninsula, south Africa. Hartlaub’s Gull frequently has low breeding success and is considered endangered in Narmbia, where 12% of the population occurs. However, the population is increasing around the urbanized Cape Peninsula where Hartlaub’s Gull has the potential to become a pest species. © 1990 Taylor and Francis Group, LLC.
