Bonnet macaque

Its distribution is limited by the Indian Ocean on three sides and the Godavari and Tapti Rivers, along with its related competitor the rhesus macaque in the north.

[1][3][4] Land use changes in the last few decades have resulted in changes in its distribution boundaries with the rhesus macaque, raising concern for its status in the wild.

[8] The bonnet macaque feeds on fruits, nuts, seeds, flowers, invertebrates, and cereals.

[10] The gestation period lasts 24 weeks and a single infant is the normal result of a pregnancy.

Lip-smacking is one of the most common affiliative behaviors, where one individual may open and close its mouth in rapid succession, with its tongue between its teeth and its lips pressing against each other, giving an audible sound.

A grimace is the most common gesture of fear or submission that a subordinate shows to a dominant individual during aggressive encounters.

A male has the best chance of obtaining a high rank in his prime age, resulting in the greatest benefits to reproduction.

Male bonnet macaques groom each other, hug each other, sleep near each other, play together and engage in male-male mounting as a social defuser.

Some mysterious environmental pressures must have driven the bonnet macaque to form an unusually egalitarian social structure.

A possible driving force may be these pacifist species inhabit more fertile habitats with more abundant food.
