One of the six black Rhinos to be transported and re-introduced to Chad's Zakouma National Park roams through an enclosed precinct getting used to enter a crate two days ahead of his relocation on May 2, 2018 at the Addo Elephants National Park in Addo, South Africa. - Six critically endangered black rhinos were en route from South Africa to Chad on May 3, 2018 in a pioneering project to re-introduce the animals to a country where they were wiped out by poaching nearly 50 years ago. Black rhinos are rated as critically endangered by the International Union for Conservation of Nature.
