Observation details
Like most large gulls, Kelp Gulls take 3-4 years or longer to reach definitive adult plumage. This is a first cycle bird. Those in Southern Africa are the distinctive race "L. d. vetula" which differs in having a dark eye, more sloping forehead, different bill shape and shorter wings. They are sometimes split as a separate species called "Cape Gull." This split was followed by SASOL until recent gene flow from South America was documented. The taxonomy is complex. Traditionally, two subspecies were recognized, but Jiguet (Bulletin of the BOC 122:50-71, 2002) has suggested there may be as many as five.
