RP, I was interested in your comment regarding the largest herd being 1,500 near Tshokwane in the 80's.
On the 13th July 2010, we saw a large herd moving Southwest across the H1-7 between Babalala and the Sirheni turn off at Boyela. Others at the sighting said they had been passing through for half an hour and we stayed another half hour and there were still more Buff making their way across as we left, but in less numbers by then. We counted a range of 25 to 50 animals per minute passing us over a twenty minute period, giving a rough estimate of 1,500 to 3,000 animals if the same numbers were to have passed by over an hour. It was impressive to watch and even if we over-estimated how many were there, I still believe there were over 1,000 animals involved in this movement. We speculated at the time that this was probably several herds that had come together to find food or water. I wonder if anyone else recorded this movement?

With reference to their ears being tattered, they often tear them on the thorns when they move through thick cover as well as other factord being involved.
