Kendi, our black rhino calf, is 1 week old and is a lively little thing. You can see him trying to spar and play with his Mom, Seiya. Rhinos are generally solitary animals but this does not stop rhino mothers from being loving and attentive to their calves. Rhino calves usually stay with their moms for 2-3 years. Males tend to leave their mothers earlier than females.
