Hartlaub's Gull
ID Features: A medium sized, pale-gray-backed gull of coastal waters and human settlements. Breeding Birds have dark eyes and a very faint chalky-gray hood, which non-breeding birds lack. The similar Gray-hooded Gull differs from Hartlaub's Gull by being larger, having a yellowish-white eye, a longer redder bill, and a discrete grayish hood in breeding plumage. Immature Gray-hooded Gulls have a black terminal tail band which juvenile Hartlaub's Gulls lack.
Habitat: This adaptable omnivore is the commonest gull of the Benguela Current, but it's penchant for eating offal means it is expending its range eastwards.
Locations: Mozambique, Namibia, South Africa
