The diet of the blue monkey chiefly comprises of fruits and figs. However, it will not hesitate to feed on insects, leaves and even flowers. Food shortage can sometimes cause these monkeys to even consume the bark of trees.


The female-philopatric social system of the blue monkeys has definitely captured the attention of animal enthusiasts. It is very interesting to note how the group mainly comprises of females with only one dominant male. Research studies discovered that the females preferred to stay back in the natal groups while the males leave as soon as they are mature. The single male gets to mate with most of the females in the group.

Alloparenting is another trait that has been associated with the blue monkeys. The infants are cared after by juvenile females and it is not unusual for one infant to be carried by several alloparents. The males basically do not have much to do with the young ones or infants.

Play and grooming are two of the most common social interactions that can be observed in a blue monkey group.

The blue monkey can be extremely territorial in nature. The only way of seeking survival is by acquiring entry into a particular group. This can only be achieved by challenging and defeating the dominant male of the group.


It is interesting to note how it is the female blue monkeys that take the first initiative to attract the attention of the males. The female extrudes her lower lip forward in a display known as pouting. Female monkeys are known to act in this manner during copulation.

The female gives birth to a one offspring. The baby blue monkey is born after a period of approximately 5 months after mating. It is indeed a spectacular sight to observe how the females of the group take care of the new born in turns.

At times some older females that have undergone the tragedy of having lost a baby may tend to get pretty aggressive by not letting o of the young one belonging to a different mother.

The young are sexually mature by the age of three.
