The Upemba Lechwe are known for the lack of dark stripes on their legs unlike other antelopes in the area, researchers say. The area the Upemba Lechwe were found is "a magical place in terms of biodiversity", Mr Weber said. In a press statement published on the Upemba National Park website, Mr Weber, described the species as "on the very brink". The fact the Upemba Lechwe is "still hanging on at all is extraordinary", Mr Weber added, but warned that they will "vanish" without "urgent protection". The photo was captured on the second and final day of the aerial survey, and taken through the windows of a Cessna aircraft, Mr Weber told the BBC.
