Scientists believe they have discovered the biggest migration of wild animals on Earth, with an aerial survey revealing vast herds of gazelle and antelope on the move in southern Sudan in a region which had been assumed to have been denuded of its wildlife by years of civil war. The Wildlife Conservation Society, together with the autonomous government of South Sudan, has announced that a study of the area’s fauna had revealed an abundance of antelope, particularly of white-eared kob, in breathtaking numbers.
