The calf had spent the first few weeks of his life bonding with his mother in private, but when he reached one-month old, zookeepers decided it was time to introduce Oban to the public enclosure, home to another six white rhinos.
After moving in yesterday, the curious youngster frolicked around and chased birds as he got know his new surroundings.
His mother Donsa, who is 32-years-old and has had 11 calves, kept a watchful eye.

Calves born in Singapore have been sent to zoos in Australia, Indonesia and Thailand as part of conservation efforts.
