"They do it basically because they are annoyed by the sound." So when hostile monkeys are around, mothers cave to tantrums to reduce the risk of harm. Consequently, why do macaque monkeys kidnap babies?
Other females in the group are intensely interested in newborns, and attempt to touch, groom, and take the infant from the mother. Sometimes they are successful in "kidnapping" the infant, and if the mother is unable to retrieve the newborn, it is likely to die.
Furthermore, what do monkeys do with their dead babies? Mother primates are also known to carry around their dead babies for some time after death, although it is not known whether the behaviour is motivated by grief or lack of awareness of the baby's death. But now, for the first time, a Tonkean macaque has been observed eating her mummified baby.
Also Know, how long do macaque monkeys nurse their babies?
12-14 months – Nutritional weaning is complete. In captivity, nutritional weaning can occur as early as 8 months of age in cynomolgus macaques. Artificial weaning (permanent separation of infants from their mothers) should not occur before 10-14 months of age.
How do monkeys make babies?
Each time though, the monkeys had helped themselves give birth. Uniquely among mammals, human babies usually face away from the mother as they are born. In other primates, including monkeys, babies are born facing the mother, who can often assist her own delivery by pulling as well as pushing her baby out.

Lion-tailed macaque: 20 years Japanese macaque: 27 years Why do baby monkeys have seizures?
Researchers have found that rhesus macaque monkeys engage in very similar behavior, in which baby monkeys pitch screaming fits until their mothers give in and feed them in order to prevent attacks from irritated onlookers. Researchers observed the behavior of wild monkeys on the island of Cayo Santiago, Puerto Rico. Do monkeys have baby teeth?
Do primates like chimps and apes have baby teeth that they lose? A. Like all mammals, primates initially feed on milk, and so need no teeth. As they begin to eat solid foods, the deciduous teeth emerge, to be gradually replaced by an assortment of permanent teeth. Do monkeys kidnap?
Observations of infant kidnapping among group-living rhesus macaques and anecdotal evidence in the literature indicate that monkey mothers do not attempt to forcibly retrieve their infants from kidnappers even though kidnapping may have potentially fatal consequences for the infant. Do monkeys have twins?
Although among other primates, such as lemurs, gibbons, baboons and monkeys, twin births, according to Dr. Yerkes, have occasionally been recorded, the higher apes, chimpanzees, orang-outans and gorillas, have not hitherto been known to give birth to more than one young at a time. Why do monkeys chatter their teeth?
Teeth chattering is seen in many primate species and has been proposed to have a range of social functions. Using these data, we tested the predictions of four hypotheses: teeth chattering functions as a signal of submission, appeasement, affiliation or reassurance. Do monkeys stink?
Primates, especially Old World monkeys and apes, are said to have a poor sense of smell, but researchers are now starting to realize that olfaction in these animals may play a greater role in their social lives than previously thought. Do monkeys breastfeed?
Like humans, monkeys generally give birth to one baby at a time and nurse them for extended periods during a time of infant and toddler-like development. Primates need this extended lactation period for social development. Why do monkeys eat their babies?
Orang-utans: Two instances of cannibalism have been documented in orang-utans living wild in Sumatra. In both cases, the mothers ate their infants after carrying their corpses around for several days. David Dellatore of Oxford Brookes University in the UK, who observed both events, thinks they were due to stress. Do apes grieve?
Thomas's death was far from the first time apes have been observed apparently grieving their dead. It is simply one of the best documented, as the events were captured on film. Why do primates carry dead infants?
Tonkean macaques—which are native to Southeast Asia—tote around their babies' corpses for hours or, even days. It could be a manifestation of grief, or an absence of understanding that the offspring is dead. How do apes clean their teeth?
The primates keep their teeth clean with improvised floss—bird feathers, coconut fibers, blades of grass, nylon thread—and are the third macaque species found to do so. Flossing is just one of the ways our evolutionary cousins use tools effectively, the researchers report in Primates. Do monkeys have periods?
Most monkeys living in Africa and Asia, such as rhesus macaques, menstruate. Great apes do it too. Menstrual bleeding is easily detectable in chimpanzees and gibbons. However, gorillas and orang-utans bleed less copiously, so menstruation is only visible on closer inspection. Do monkeys give birth like humans?
Chimps give birth like humans. Remarkably, before Hirata and his colleagues filmed three captive chimpanzees giving birth, nobody had observed chimp parturition at close quarters, and the animal's young were assumed to be born facing forwards, as are those of many other non-human primates. Why do monkeys kidnap babies?
If an infant dies, the mother will not reproduce again until the next year, thus "kidnapping" may be a way for high-ranking females to decrease the reproductive success of low-ranking females in the group. How long do monkeys carry their babies?
Even within the species of apes and monkeys gestation period seem to be a matter of size. For Rhesus monkeys it is 164 days and baboons 187 days. For small animals such as rabbits the period is about 33 days and for mice about 20 days. Do monkeys give birth?
Each time though, the monkeys had helped themselves give birth. Uniquely among mammals, human babies usually face away from the mother as they are born. In other primates, including monkeys, babies are born facing the mother, who can often assist her own delivery by pulling as well as pushing her baby out. Do monkeys walk at birth?
