[QUOTE="Mike Richardson, post: 3557687, member: 43216"] The conspicuous nose spot is also mentioned as an Acacia identification feature in [I]Bovids of the World[/I], along with the darker flank stripe (to differentiate it from the Dorcas). There are at least 6 head on photos of Dorcas Gazelles in the book (both subspecies are illustrated; male, female and young of each) and none show a nose spot like that seen in the Acacia Gazelle. However, as you say some Dorcas do clearly show a darker patch on the nose, although perhaps not as distinctive. I think your method of looking at a suite of features to pick out the Acacia Gazelles works best. Any gazelle without an obvious nose spot can be safely assumed to be Dorcas. [/QUOTE]
