context_page_description: The toque macaque is a reddish-brown-coloured Old World monkey endemic to Sri Lanka, where it is known as the rilewa or rilawa.
context_section_description: When in estrous, the female's perineum becomes reddish in color and swells. This change is a signal to the males that she is ready to mate. There is an average of 18 month between births. After a 5–6 month gestation period, female macaque give birth to a single offspring. Offspring hold on to their mothers for about 2 months. During this time they learn survival techniques and social skills critical for survival. The infants are born into their social classes based on their mothers position in the troop. Young males are forced to abandon their troop when they are about 6–8 years of age. This prevents in-breeding and ensures that the current alpha male maintains his position in the troop. Leaving the troop is the only way a male can change his social standing. If he has good social skills and is strong he may become an alpha male. A single alpha male can father all of the troops' offspring.
  Birth rarely occurs during the day or on the ground. During labor the female isolates herself from the group (about 100 m). The mother stands bipedally during parturition and assists the delivery with her hands. The infant is usually born 2 minutes after crowning. The infant can vocalize almost immediately after birth; it is important for the mother and infant to recognize each other's voices. Vocalization will be used to alert the mother of imminent danger, and can assist in finding each other if separated. After birth the mother licks the infant and orients it toward her breasts. She will resume foraging behavior within 20 minutes after parturition. The mother also eats part of the placenta, because it contains needed protein. The alpha female of the group asserts her power by taking part of the placenta for herself to eat.
