agreed on theory that its was a lightning strike followed by animals feeding on carcas later. The group were to tight together for an attack, also no tracks of them milling around. I do not know wolves but see no bike marks all over the carcas, like the heels, throat etc.
Wonderfull thread to track. The remoteness and beaty of the area is stunning. Some of the birds come all the way down to South Africa in summer, for excample, Red Footed Falcon.
