@FunkyGibbon : It is not antelopes but empty markhors statues. The belly of some of them is used as container for large pieces of meat. When the "show" starts, the animator simply open the belly of the animal and all vultures come rushing on the piece of meat. While vultures are fed, the animator explain the scavenging role of vultures and how the four european species are "coordinated" around new carcass.
It is really specatcular and educationnal.
And I confirm Lintworm previous message, all vultures are "naturally" unable to fly. However some manage to fly a little bit and the team had to put a 2 meters high net on top of the steel wall.
