 So where are the antelope coming from and where are they headed during this migration? And is it an annual one? It is. These animals are always moving. That many animals can't stay in one place. So they'll be moving across an area of about 200,000 square kilometers, so 20 million hectares. The white-eared cob, which is the largest aggregation, there's 5 million of them. They're moving really from the Burma National Park to Badangilo, crossing the great floodplains of the White Nile.
