Footage of three black rhinos, taken from Kent to Tanzania to boost the population of the critically endangered species, has been released by conservationists from the Aspinall Foundation.
The animals, called Grumeti, Monduli and Zawadi, travelled from Port Lympne Wild Animal Park to their heavily protected reserve in Tanzania earlier this year.
Prince William paid a private visit to them and their keepers at the wild animal park, near Ashford, before they travelled.
