Hartlaub's gull is a small seabird that lives only on the coasts of South Africa and Namibia. The adult bird has a white head, light gray back, and bright red beak and legs.
Hartlaub's Gull differs from other gulls by its completely white head during the breeding period and small body size. It is important for nature because it eats waste and regulates the population of small marine animals on the coast.
