Nairobi attractions: The black rhino is blind. It was rescued from the Nairobi NationalPark after being rejected by the mother when it was three monthsold because of his blindness. ‘We try to help him with surgery, butwithout success. The rhino has blindness genes. So he can’t goback to the wild. He has to stay with us all of his life,’ said a handlerat the David Sheldrick Elephant and Rhino Orphanage. The rhino isnow 12 years old. It has an average lifespan of 35-40 years.
