But until Mike Fay and Paul Elkan, scientists with the Wildlife Conservation Society, began conducting aerial surveys of southern Sudan in January, the world had little idea the savannahs were covered with 1.2 million white-eared kob, tiang antelope (shown in photo) and Mongalla gazelles parading in processions up to 50 miles long.
