Yorkshire Wildlife Park welcomes baby black rhino

A baby black rhino - one of the rarest mammals in the world - has been born at Yorkshire Wildlife Park in Doncaster.

The calf is now three weeks old and has been spotted eagerly exploring the reserve with his mum.

Black rhinos are critically endangered and the group living at the wildlife park in South Yorkshire is part of an international breeding programme attempting to revive the species.

Staff at the park say the arrival of the calf was a "very special birth", adding that he is already well on his way to becoming a "visitor favourite".
