The Pigtail Macaque are common in Khao Yai National Park and yet this monkey is actually listed as Vulnerable; it is found in the southern half of the Malayan Peninsula, Borneo, Sumatra, Bangka Island, and Thailand. It is mostly found in rainforests up to 2000 meters but they also invade orchards, farmlands, gardens, and plantations.

This monkey is terrestrial but a fantastic skilled climber and loves the water unlike most primates. It lives in large groups but joins smaller groups as they look for food. it is omnivorous feeding on fruits, seeds, berries, cereals, fungi, and invertebrates.

The males practice hierarchical behaviour based on strength and among females, based on heredity. Therefore, the daughter of the dominant female becomes above all other females in the group, leads the group; the dominant male manages conflicts within the troop and also defend.

There is a hierarchy among males, based on the strength, and among females, based on heredity. Thus, the daughter of the dominant female will immediately be placed above all other females in the group. The dominant female leads the group, while the male role is more to manage conflict within the group and to defend it.

This also the kind of monkey in which the Thais train to harvest coconuts at the plantation, saving farmers from paying climbers to harvest and avoid human accidents as this monkey is an expert climber.
