The baby rhino - who has not yet been named - was born to mum Behan and dad Hugo at 5am on Sunday, December 8.

At 70kg, the youngster weighed more than 20times the average 3kg human at birth and was born with furry ears and soft pink folds of skin, which will toughen to form the characteristic 'armour-plate' the rhinos are known for.

Mark Holden, ZSL team leader, said: "We knew Behan was expecting so ZSL's zookeepers have been keeping a close eye on her throughout the 16-month-long pregnancy - we checked on her the night before and found her calm and relaxed in her indoor dens.

"Coming in early the following day they were delighted to find a healthy female calf standing next to her mother, having been born in the early hours."

The calf's name is being chosen by one of ZSL's supporters and will be revealed in the new year on ZSL's social channels.

Born as part of the European Breeding Programme (EEP) for the species, the calf is Behan's fifth calf and the 15th greater one-horned rhino to be born at Whipsnade, which was one of the first zoos in the world to breed the species in 1957.
