Whilst sitting at a waterhole in Etosha National Park a couple of weeks ago, we noticed a hyena approaching the water. It had a drink and then started wading into deeper water whilst sniffing the air around.
It then dived numerous times and was obviously struggling to raise a putrid carcass from the bottom of the pool
Then a second hyena arrived and looked at what was happening. When the one in the water saw it, it immediately swam back to the edge and walked out of the water hole.
They sniffed each other and the first behaved very submissively, until it eventually slunk away with its tail between its legs.
