How many bat-eared foxes are left in the world?

The IUCN (International Union of Conservation of Nature) classified the bat-eared fox as a "Least Concern" species, however, it only has a "Restricted Range" and estimates the total population to be between 100,000 and 500,000 individuals. However, the IUCN states that this is a rough estimation, and the actual number of bat-eared foxes may be lower or higher than the estimated range.
