Gemsbok - new antelope species in Bojnice

Which species exactly is this?

These are 'proper' South African Gemsbok, Oryx gazella (gazella). The easiest way to spot this form is that neither Beisa (O. b. beisa) nor Fringe-eared Oryx (O. b. callotis) have the black patch at the top of the hind leg.

Beautyful picture, and anilopes, congratulation

Nice picture.
