The encounter took place in the Lower Zambezi National Park, Zambia.
“We have seen the pack attempt to hunt among a herd before, trying to separate a youngster or a weak individual, but had never seen them have any success,” said Nicholson.
He said the sighting was “extremely emotional” and lasted more than 20 minutes.
“This particular afternoon they started harassing the herd as usual and then chased them into a woody area where they managed to separate an adult female from the herd.
“They then went into overdrive and started biting and attacking her hindquarters and legs. Several other buffalo attempted to chase the wild dogs off, with a few wild dogs countering and chasing them away each time. This allowed most of the pack to continue their attack on the female,” said Nicholson.
