There is so much expression in the eyes of a primate and you have to wonder what is going through his mind. This male Olive baboon was beginning to tire and was looking to get some sleep. With us nearby he was unwilling to close his eyes. We assume as soon as we left he closed those expressive eyes and got some deserved sleep.
Of course, if you have recently been born into this wonderful world then you have little use for sleep and would rather explore this new and curious planet. Everything is new, exciting and interesting so why sleep? This young Olive baboon was fascinating to observe and proved to be very photogenic and interested in us. Mom, however, is never far away. She is allowing her baby to explore and learn about this new environment but within limits. Should this calm situation change then she will immediately intervene to protect her baby.
Of course, the male baboon is really in charge of the entire encounter. Here he is grooming the female and picking off insects and parasites. Just below his eye is a wound probably received from a fight with another male baboon. It is a tough job being a male baboon and protecting your status as the dominant male.
