Three critically endangered black rhino from Port Lympne Wild Animal Park in Kent have been relocated to the wild.
The two females named Grumeti and Zawadi and one male named Monduli attracted royal attention when Prince William, the Royal Patron of Tusk Trust, paid a private visit recently.
The three rhinos were flown from Manston airport to a refuelling stop in Bergamo, Italy, and then on to Kilimanjaro National Airport in Tanzania.
Eastern black rhino are the rarest of the three remaining rhino subspecies left in Africa.
Adrian Harland, animal director said: "Our dedicated keepers have been working closely with Monduli, Grumeti and Zawadi over the last few months, preparing them for life in Tanzania.
"Their diet has been altered and the keepers have been with them every day using a lot of contact techniques in order to reassure them during the flight and at their new home. I’m delighted that the move went so smoothly and I have to thank everyone involved for making this operation successful."
