Vervet Monkey (Chlorocebus pygerythrus). South Luangwa NP, Zambia. We were on a game drive and saw a group of vervet monkeys in some large trees close to the track. This lone monkey sat for some time in the middle of a particularly large tree. Though I'm sure he was able to scamper up into the tree quite easily, he did look as if he was taking his time to build up the courage to attempt the climb.
