Buffalo usually move in herds, so there's something odd about him. It may be that it was brought up as a calf and is humanised. Or it may be that he's an outcast from the herd in some way and that he's rather grumpy and fed up with life. But I think it's just hot and he's just plodding around and wondering where he might get a drink and a decent sandwich. I feel the same way myself, actually. The team's filming has coincided with the newest arrival at Lewa, a baby rhino in need of 24-hour care. This little chap was born blind and is guided everywhere by his keepers. They took him away from his mother a few weeks ago, because she couldn't protect him any more. He's very vulnerable so he would have been killed by predators. It's like filling up a petrol tank. Every rhino is precious
