To cope with the 3,100-mile flight, the rhinos were given sedatives.

After 40 hours, they landed on Monday in their new home, a national park in eastern Rwanda.

It is said to be the most extensive migration of the species ever and the purpose is to protect the rhinos.

- This gives them the opportunity to grow in a safe environment instead of in South Africa where poachers shoot three a day, says the regional park manager Jes Gruner according to the news agency AFP.

There are two subspecies of the white rhino.

The northern variant is basically extinct - only two female specimens remain.

The southern variant is endangered, but the number of individuals amounts to just over 20,000.
