About the Hartlaub's Gull
Hartlaub's gull is a small gull in the genus Chroicocephalus. It was formerly placed in the genus Larus until genetic research demonstrated that the old broad view of that genus was paraphyletic. In the past it had sometimes been treated as a subspecies of the Australasian silver gull, but is now treated as a separate species; current genetic evidence suggests its closest relative is not the silver gull but the African and South American grey-headed gull, and in particular the African subspecies of it C. c. poiocephalus.
