From the BBC:
‘World first’ rhino birth on web
The birth of a rhino is to be captured on a BBC-run webcam in what zookeepers believe will be a world first.
The zoo said there was no existing footage of a black rhino being born in a zoo anywhere in the world.
The birth, the zoo’s first rhino calf, is part of its on-going endangered species programme.
The baby rhino was born 5 March; update here.
