First, the animals will look at you in the eyes, open their mouths, and bare their teeth. Rhesus macaques, the aggressive monkeys that cause a lot of the trouble in Delhi, will then warn you with a grunt.
A "threat" face (open mouth, ears and forehead forward, presumed to be the expression for anger, when a monkey is threatening others) A "lip smack" (lips are smacked together over and over again, presumed to be the expression for affiliation or appeasement)
Myth: Chimps can smile like humans do.
Chimps make this expression when they are afraid, unsure, stressed, or wanting to appear submissive to a more dominant troop member. The closest expression chimps have to a smile is a play face.
In primates, displacement behaviors can include scratching, auto-grooming, shaking (similar to a wet dog), and yawning. Other signs of anxiety or fear in NHPs include piloerection, or making oneself look larger (Hinde and Rowell 1962).
Monkeys often fight with their hands, arms, and will bite. Monkeys are not typically very aggressive, unless it is mating season, they are provoked by another monkey or feel that they are in danger. Monkeys are very social animals that live in large groups.
If a macaque makes a surprised-looking face with an open mouth, wide eyes, and raised eyebrows, it's angry at you and warning you to back off. If it leans forward toward you while doing this, it's an outright threat; the next step is to run toward you and try to chase you away.
Similarly, don't yell at a monkey or otherwise tease / heckle it. Take care with your body language and don't make sudden movements – any perception of aggression or threat will increase the chance of a monkey attack.
Monkeys are scared of snakes. Keep real looking plastic snakes at roof tops or boundary wall of your house. Loud heavy noise, bursting of crackers or their sound track will force the monkeys to leave any premises. An injured monkey should be helped when monkey group is not close by.
One key behavioural correlate of stress, common particularly within the primates, is scratching (i.e the repetitive raking of the skin on face and/or body, with the fingers of the hand or feet)7.
Chemical repellents: active substances such as Anthraquinone, Butanethiol, and Methyl Anthranilate can be used to keep monkeys away from crops. Thimet granules @10gm mixed with 2 g of sand kept in punched polybags in the border area will repel away the monkeys.
In most primates, eye contact is an implicit signal of threat, and often connotes social status and imminent physical aggression. However, in humans and some of the gregarious nonhuman primates, eye contact is tolerated more and may be used to communicate other emotional and mental states.
It is easy to tell when a chimp gets mad: they become aroused and perform conspicuous displays and noisy tantrums. The researchers found that the chimpanzees were more likely to collapse the table when they were aroused than when they were calm.
Abstract. Nonhuman primates posses a highly developed capacity for face recognition, which resembles the human capacity both cognitively and neurologically.
Monkeys, apes and other simians have nothing quite like our tears. They have tear ducts to help keep their eyes lubricated and clean. But they don't drain when they're sad. Chimps will scrunch up their faces and make noise when they're in distress, but they don't connect the tears and the wailing.
If you are holding a snack, throw it in their direction, and they'll stop bothering you. If you don't have any food, hold out your open palms to show you're not carrying a tasty treat or back away from the monkeys without showing fear.
Monkeys do not cry, at least not the way we do. Humans are the only primates to respond to feelings of extreme grief, anguish, pain, sadness, or frustration by releasing tears and weeping.
Strengths: sociable, clever, curious. Weaknesses: unreliable, mischievous, disrespectful.
Vervet monkeys tend to scream when they are involved in aggressive interactions, but these can vary from relatively mild situations, such as being stared at in an intrusive manner, or just hearing a dominant male making an aggressive grunt, to those that are rather more serious, all the way up to violent biting attacks ...
Chimpanzees laugh when they play and cry when they grieve. They experience and express joy, anger, jealousy, compassion, despair, affection, and a host of other emotions. Touching and grooming are vital to maintaining stable relationships and keeping the peace within the community group.
Firecrackers, gunshots, and other loud noises are good measures to scare off monkeys.
Why did humans and monkeys evolve to hate the color red?
Big cats are the primary predators for monkeys who spend the majority of their time in trees, but when the primates venture out of the canopy, they can be vulnerable to water predators like snakes and alligators.
As babies they are adorable and sweet, but once they hit puberty (around age 3) their demeanor will completely change. They will become unpredictable, aggressive, unmanageable, and dangerous, often biting and scratching even their most favored caregiver.

Monkeys that are in distress or pain or babies that are separated from their mothers vocalize their distress in whimpers, screams, and other sounds that can very well be described as crying. Young monkeys are even known to throw tantrums when they do not get what they want.
