I saw a lot of tracks of black rhinos, but I have never been able to see one in real.
The first time, it was in a big private farm along the Nyae-Nyae conservancy in Namibia where rhinos were placed by the government. I don't remember how many black rhinos there was in that farm but tracks were everywhere. That farm also had the biggest population of leopards I have never seen. We also saw tracks everywhere and everyday. It was in that farm where I was able to see my first leopard, a female, in the daylight. That place was a true heaven with a great management. When we stalked plains game, my PH told me if there was a rhino charge, run ! He told me, it happenned to him a couple of times.
The second time, it happenned in a farm along Etosha. A black rhino escaped from the park, because elephants broke the fence few days before my arrival, and the black rhino arrived on the farm where I was hunting. People from the park spent a lot of time patroling on the farm to locate the animal, and bothered us. Despite a lot of walk and glassing from hills, we never spotted the rhino with my PH despie we crossed its tracks several times a day. But when rangers located it, they called the helicopter to dart the animal and to transfert it into the park. I saw the helicopter very far away, but not the animal. I heard Pohamba Chifeta was there.
I saw a lot of white rhinos but they were not wild at all.
