The hyenas of the Ngorongoro crater are becoming so aggressive that they are hunting in packs to take down their own prey. We witnessed (from a distance), hyenas attack and kill a young zebra (maybe 18 months old) and then eat it. Taking this leg back to the den for the pups is one of the spoils. We also witnessed an unsuccessful attack on a wildebeest that although severely wounded, survived by jumping in the hippo pool…. the hyenas did not follow. Many of the lions in the crater looked skinny and hungry. When asked, our guides said that the hyenas are running lions off so many kills that they are going hungry.
