Taxonomy of the Kelp Gull Larus dominicanus Lichtenstein Revisited with Sex-Separated Analyses of Biometrics and Wing Tip Patterns

sub-Antarctic islands) and L. d. melisandae (from Madagascar). We failed to find differences among birds from Antarctica, South Georgia, and the Falklands Is., and suggest that the range of L. d. austrinus could extend from the Antarctic Peninsula to these sub-Antarctic islands. Populations sampled in southern Patagonia appeared close to L. d. austrinus, although they might also represent populations intermediate between L. d. dominicanus and L. d. austrinus. The subspecific status of L. d. antipodus from New Zealand populations was suggested by phenotypic characters, while a recently published molecular study of Kelp Gull populations suggests wellseparated clades for birds breeding in New Zealand, Antarctica, and the Kerguelen Is., while the genetic separation of birds from South America (L. d. dominicanus) and Namibia (L. d. vetula) needs further study. We recommend further molecular studies of this widely distributed species before making further definitive taxonomic recommendations. http://zoolstud.sinica.edu.tw/Journals/51.6/881.pdf
