This pride male was calling the other pride male, who was under a tree that had a leopard kill in it. The leopard (female - we saw her later) had killed an impala and the 1st male had followed the scent of the kill to the tree. The male in the video crossed the water, called again, and then met up with the other male. Soon after this we found one of the females of the pride with her cubs - the same ones I had seen exactly a month earlier on the tracking trip.
