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 wayand that he's rather grumpy and fed up with life.But I think it's just hot and he's just plodding aroundand wondering where he might get a drink and a decent sandwich.I feel the same way myself, actually.The team's filming has coincidedwith the newest arrival at Lewa,a baby rhino in need of 24-hour care.This little chap was born blindand 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 preciousand so it seems a fitting endfor the final scene of the series.
