The critically endangered black rhino calf Moyo, born last week, can be seen in the zoo's footage enjoying nose rubs from a keeper.

He can also be seen in the video taking some of his first steps, and learning to walk on his own.

While Moyo is still tiny, he could grow to become more than 3,000 pounds — which is about as heavy as a car.

Moyo, which means "heart" in Swahili, is spending time behind the scenes where he is nursing well and bonding with his mother Kati Rain and father Ajabu.
