H. G. C. Swayne, Seventeen trips through Somáliland
“ They are, I think, the most stupid and easy to shoot of all the Somáli antelopes, and their habits are identical with those of the Indian blackbuck, but they are not equal to it in beauty and grace of movement. Aoul often make long and high jumps when going away, presumably to look over the backs of the others; they look something like specimens of the Cape springbuck which I have seen in England. I have never observed them spring vertically to a great height, as the Indian blackbuck does. They are inquisitive like the hartebeests, and will follow a caravan in the open ”
