To date, we know of 37 wild born elephant calves because their mothers, orphans living back in the wild, have chosen to share their new bundles of joy with us by returning to our Reintegration Units sometime after the birth. However, we are certain there are many more wild born babies, fathered by male orphans living back in the wild who have mated with female wild elephants. There is also a wild born rhino calf, in the shape of Sultan, a black rhino born into the Nairobi National Park rhino population. All are protected by our Anti-Poaching and Aerial Surveillance Projects, carried out in partnership with the KWS and funded by our global supporters.
