In many species, things like play-fighting, chasing, and even games of stealing from each other are forms of recreation and amusement. There's one behavior, however, that is nearly universal: grooming. Social grooming is one of monkeys' favorite things to do.
Most monkeys live in large social groups and spend the majority of their day searching for food and socializing. Some species may spend time grooming one another, playing, communicating and forming social bonds with one another.
Swings and other large toys that can be hung in the monkey habitats to swing or climb on. Old-fashioned activity centers with moveable parts. Small toys they can carry in their hands or tails such as rattles. The 'rainstick' rattles are great favorites!
The term "monkey" is sometimes used as a catch-all for every animal in the primate family, but the truth is that monkeys live on completely different branches of the evolutionary tree from both apes (i.e., chimpanzees, gorillas, and humans) and prosimians (i.e., lemurs, tarsiers, and lorises).
Myth: Chimps can smile like humans do.
The closest expression chimps have to a smile is a play face. A chimpanzee enjoying a good tickle session with another chimp may show their bottom row of teeth with their mouth open and relaxed.
Some scientists suspect spontaneous smiles in these monkeys echo the development of our own expressions. Scientists from the Primate Research Institute at Kyoto University in Japan have observed these spontaneous smiles in Japanese macaques for the first time, according to a new study published in the journal Primates.
Chimps also use laughter as a social lubricant, according to a study in press in Emotion. Researchers from the University of Portsmouth in England spent months videotaping four captive chimpanzee colonies — with nine to 35 apes in each group — and captured 642 instances of laughter.
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.
Turns out, chimpanzees use hugs and kisses the same way. And it works. Researchers studying people's closest genetic relatives found that stress was reduced in chimps that were victims of aggression if a third chimp stepped in to offer consolation. "Consolation usually took the form of a kiss or embrace," said Dr.
“You'll often see the male approach the female and sometimes he'll tap her or get in her face to get her attention and he'll make faces such as lip smacking, where it's rapid movement of the lips, or jaw thrusting, where the lower jaw is stuck out and the head is raised.
A study from 1936 even offered monkeys fruits, vegetables, nuts, and bread to see what they would choose to eat more of. Bananas ranked right behind grapes; nuts and bread were last. "Of course monkeys and apes are not stupid and relish eating them once they are exposed to them," Milton said.
They especially like moths, beetles, and spiders, which are more active at night, allowing owl monkeys to find them. Capuchin monkeys are omnivores who mostly eat fruit, insects, leaves, small lizards, birds' eggs, and small birds.
Brain Food
"The whole carcass is valuable, but the brain is especially valuable." Brains are high in fat and a source of long-chain fatty acids, which aid in neurological development. A chimpanzee captures a young red colobus monkey during a hunt.
When monkeys get aggressive, it's usually because they think you have something to eat. According to one study, about three-quarters of all the aggressive interactions between long-tailed macaques and tourists at Bali's Padangtegal Monkey Forest involved food.
Their young learn by reaching out with their hands to experience the world around them, grasping new objects, slowly piecing together an understanding of their society. They learn from their families how to find food, communicate, recognize kin, even use tools, medicine, and language.
It was long assumed that only humans can distinguish the living from the dead. Renewed interest in this question over the last decade has led several authors to assert that non-human primates are also aware of death.
Indeed, studies have shown that chimpanzees and macaques not only seek revenge, but often do so intelligently — for instance, if they see that their adversary is stronger than them, they attack a weaker relative instead.
Based on behavioral observation, trained observers can say a monkey looks depressed. Because their emotional behaviors are similar to that of humans, just by looking at their facial expressions or the way their gaze is directed, we can get an indication of whether an animal may be experiencing sadness.
“If you smile at a rhesus monkey it may interpret your show of teeth as an aggressive gesture and respond violently.”
The reason they do this is to reduce their stress levels and also to strengthen the bonds within the group. Plus, it keeps their fur bug free! If you see our macaques 'chattering' their teeth together, then don't worry, it's not a sign of aggression.
While they do kiss with their lips, their smackers are narrower and don't turn out like ours do. Researchers speculate that this anatomical difference could mean that kissing for chimps is not particularly intimate, but rather an expression of connection like the human hug.
Tiny primates form close bonds that may be foundation of human relationships. It may not seem like monkey business, but emotional bonds in animals such as primates may have evolved into love as we know it.
Lip smacking is a social behavior that usually results in friendly interactions between monkeys in a social group. Often, a monkey will lip smack to a more dominant monkey as a sign of submission.
"A bonobo might request [a hug], so they will seek someone out and sort of ask for help, or somebody might offer them one," Clay said. It's difficult to judge animal emotions, but the evidence points to the likelihood that hugging reassures these primates, just as it does humans, Clay said.
