Nineteen beisa oryx antelopepreviously thought to be extinct in Southern Sudanappear to chase the shadow of a survey plane in Boma National Park.
Surveys of the region in January 2007 covered 58,000 square miles (150,000 square kilometers). The survey team also confirmed the presence of at least 4,000 Nile lechwe, a type of antelope that was also believed to have disappeared from the region.
"It's like nothing you've ever seen in your life," said J. Michael Fay, a member of the survey team. "You just can't believe that many animals could have survived."
