MIke,

Good wildebeest it seems that the same family of animals are all inquisitive that is the hartebeest's, wildebeest's and the blesbuck and bontebok.

What also works is to lay down behind a bush and make some natural noises like breaking twigs or russteling some leaves they just need to know what it is making that noise. Whistling soflty also worked once. But don't try it if there is a whole heard of them only with one or maiximum 3 animals.
