Except for the fence and the metal pole, this shot looks like it could have been taken in South Luangua National Park in Zambia.
Good point, but the Thornicroft's giraffes in Zambia look like they are very closely related to the Masai giraffes, if not directly a geographically isolated population of Masai giraffes. This is based on mitochondrial DNA sequences found in Russell Seymour's PhD thesis.
@DAVID Brown: Good point too. As in so many cases when classifying species/subspecies, it is a question of which scientist you will follow/believe (No matter how your decision is, a few years later it will be wrong either, because another scientist will have found "evidences" for another kind of relation)...
