Species of New World monkey

The black striped capuchin (Sapajus libidinosus), also known as the bearded capuchin, is a New World monkey in the family Cebidae. They can be found in northern and central Brazil. These capuchins mostly live in dry forests, and savannah landscapes between the Rio Araguaia and the Rio Grande. Known for its tool use, the black stiped capuchin has been shown to use tools in a wide variety of situations, ranging from using rocks for nut cracking to using sticks for digging. They were, until recently, considered a subspecies of the tufted capuchin, but because of more research and insights, they are considered their own species by many. They often live in highly social groups ranging from 6 20 individuals. Females are philopatric, show coalition, and linear dominance hierarchy. Females reach sexual maturity around 5 years of age and give birth about every 24 months to a single infant.

The black striped capuchin is a New World monkey and a member of the Cebidae family, which contains both capuchins and squirrel monkeys. Until the past few decades, the black striped capuchin was considered a subspecies of the tufted capuchin but has slowly become accepted as a separate species over time. Even within the black striped capuchin species, we see more taxonomical debate, as the southern population is sometimes considered a species of its own as well, called Azaras's capuchin. Males will react first with disinterest and aggression, this is followed by a behavior dubbed "touch and go". Females will touch a male, and then flee before the male can inflict aggression. After some time, males react with interest and the pair can mate. Black striped capuchins look very similar to other tufted capuchins, but importantly, they have a lighter coloration on the lower portion of their face, which earned them their name. Sticks also seem to be used to probe as well as dip for honey in the wild. Stones play an interesting role in reproduction, as females will throw them at males for attention. Males have been seen to use sticks and tools more often than females. When studied, it was clear that females use tools at the same rate as males for the first 10 months, but after that, due to environmental surroundings, they use sticks less and less compared to males. This use of tools is a very well defined trait in black striped capuchins and has been traced back over three thousand years. This is so well defined that the forearm muscles in black striped capuchins are well defined for complex tool use. In their natural environment, black striped capuchins are diurnal and spend much of their day travelling in search of food, especially since they live in drier areas. From this variety they especially eat fruits.

Black striped capuchins can be found in northern and central Brazil. Specifically, in the Cerrados, Caatingas, and Pantanal of Brazil.
