Chroicocephalus hartlaubii (Hartlaub's Gull)

Synonyms: Larus hartlaubii

Wikipedia Abstract

The Hartlaub's gull or king gull, (Chroicocephalus hartlaubii) is a small gull, which is a non-migratory breeding resident endemic to the Atlantic Ocean coastline of South Africa and Namibia. Although it is predominantly coastal or estuarine, it is not a pelagic species, and is rarely seen at sea far from land. It was formerly sometimes considered to be a subspecies of the silver gull (C. novaehollandiae), and, as is the case with many gulls, it has traditionally been placed in the genus Larus but is now placed in the genus Chroicocephalus.
