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. [3] Known for its tool use, the black-striped 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. [4] [5] [6] [7] 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. [8]
They often live in highly social groups ranging from 6-20 individuals. Females are philopatric, show coalition, and linear dominance hierarchy. [9] 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[ when? ], the black-striped capuchin was considered a subspecies of the tufted capuchin but has slowly become accepted as a separate species over time. [10] [11] 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. [8]
In black-striped capuchins, we see an interesting mating behavior. When a female decides she is ready to mate, she will follow a male around attempting to get his attention. This can happen in various forms, one that has been described is the act of throwing rocks and sticks. [12] 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. [3] [9]
Females have offspring on average once every two years to a single infant. This infant will be initially carried on the mothers belly, but will transition to her back. They forage independently at two years of age, and are weaned slowly. [3]
Black-striped capuchins have only a few physical features that distinguish them from other tufted capuchins. Similarly, to other tufted capuchins they have thick and strong tails. They have fur colored light to dark brown on their body, with darker black fur on their tail, arms, legs, and head. They get the name "bearded capuchin" because they tend to have darker faces, but lighter hair around their mouth and lower face. [3] As they reach sexual maturity, they get dark spots on their head as well as sideburns on their face. Yet the features that most distinguish them include their orange fur on their neck as well as their yellow tinted fur on their dorsal side.
Males and females often have a similar height of around 37 cm (14.6 in) but show strong sexual dimorphism in their weights, with males around 3.5 kg and females around 2.1 kg. [13] 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. [3] The bearded capuchin can live up to 25 years in the wild, but much longer when in captivity. [3]
The black-striped capuchin is best known for its use of tools. Their use of tools can be found in many aspects of their life and they were the first non-ape primate to have been documented using tools. They have been known to take nuts, place them on a stone anvil, and use another stone to crack them open. [5] Aside from that, they have also been seen using tools to dig in the ground. [4] Using tools to dig, they can find foods like roots, tubers, as well as scare prey out of hiding spots. [14] 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. [12] The monkeys also have found ways to use tools as a form of intimidation. It has been shown that they also use stones to make loud noises in order to intimidate potential predators. [15]
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. [16] [17]
This use of tools is a very well defined trait in black-striped capuchins and has been traced back over three thousand years. [18] This is so well defined that the forearm muscles in black-striped capuchins are well defined for complex tool use. [19]
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. [3] This leads them to spend more time travelling terrestrially, primarily quadrupedally and rarely walking bipedally to use tools. [3]
The diet consists of a wide range of foods. Fruits, nuts, insects, small vertebrates, flowers, and leaves. [20] [21] From this variety they especially eat fruits. [3]
Black-striped capuchins can be found in northern and central Brazil. Specifically, in the Cerrados, Caatingas, and Pantanal of Brazil. [21]
The Cebidae are one of the five families of New World monkeys now recognised. Extant members are the capuchin and squirrel monkeys. These species are found throughout tropical and subtropical South and Central America.
The Panamanian white-faced capuchin, also known as the Panamanian white-headed capuchin or Central American white-faced capuchin, is a medium-sized New World monkey of the family Cebidae, subfamily Cebinae. Native to the forests of Central America, the white-faced capuchin is important to rainforest ecology for its role in dispersing seeds and pollen.
The golden-bellied capuchin, also known as the yellow-breasted or buff-headed capuchin, is a species of New World or neotropical monkey. It lives mainly in trees and are omnivorous, eating a wide variety of both plant and animals as food. Golden-bellied capuchin normal home range is in the Atlantic forest of Brazil and it is critically endangered due to forest fragmentation and habitat loss mainly due to agriculture, there are currently efforts to protect them by the local government.
The capuchin monkeys are New World monkeys of the subfamily Cebinae. They are readily identified as the "organ grinder" monkey, and have been used in many movies and television shows. The range of capuchin monkeys includes some tropical forests in Central America and South America as far south as northern Argentina. In Central America, where they are called white-faced monkeys ("carablanca"), they usually occupy the wet lowland forests on the Caribbean coast of Costa Rica and Panama and deciduous dry forest on the Pacific coast.
Serra da Capivara National Park is a national park in the Northeastern region of Brazil. The area has many prehistoric paintings.
The tufted capuchin, also known as brown capuchin, black-capped capuchin, or pin monkey, is a New World primate from South America and the Caribbean islands of Trinidad and Margarita. As traditionally defined, it is one of the most widespread primates in the Neotropics, but it has recently been recommended considering the black-striped, black and golden-bellied capuchins as separate species in a new genus, thereby effectively limiting the tufted capuchin to the Amazon basin and nearby regions. However, the large-headed capuchin (S. a. macrocephalus), previously defined as a distinct species, has been reclassified as a subspecies of the tufted capuchin, expanding its range east to Peru and Ecuador and south to Bolivia.
The Kaapori capuchin, also known as the Ka'apor capuchin, is a species of frugivorous, gracile capuchin endemic to the Brazilian Amazon. Their geographical home range is relatively small and is within the most densely populated region of the Amazon. With the strong human presence nearby,C. kaapori has had to deal with very large amounts of disturbances to their habitat and is one of the most endangered of the neotropical primates.
The wedge-capped capuchin or Guianan weeper capuchin is a capuchin monkey from South America. It is found in northern Brazil, Guyana and Venezuela. Cebus olivaceus is known to dwell in tall, primary forest and travel over long distances during the day.
The black capuchin, also known as the black-horned capuchin, is a capuchin monkey from the Atlantic Forest in south-eastern Brazil and far north-eastern Argentina. Historically, it was included as a subspecies of the tufted capuchin.
The large-headed capuchin is a subspecies of the tufted capuchin monkey from South America. It is found in Bolivia, Brazil, Colombia, Ecuador and Peru. It was formerly thought to be its own species, but studies have found it to be a subspecies of the tufted capuchin.
The blond capuchin is a species of capuchin monkey endemic to northeastern Brazil. This endangered species was rediscovered in 2006. It can live in exceptionally large groups of over 150 individuals, and like other capuchin species, exhibits a complex and high level of sociality. It is threatened by loss of habitat due to agriculture, primarily sugarcane fields. In many cases this has caused sugarcane to make up a large portion of their diet, which would otherwise consist of mostly fruit and small animals. The blond capuchin is known to inhabit both the Atlantic forest and Caatinga biomes, although the habitation of the Caatinga may be a recent choice caused by human encroachment into its former habitats. Like other primate species, the blond capuchin is also threatened by poaching and capture for the illegal pet trade.
Pedra Furada is an important collection of over 800 archaeological sites in the state of Piauí, Brazil. These include hundreds of rock paintings dating from circa 12,000 years before present. More importantly, charcoal from very ancient fires and stone shards that may be interpreted as tools found at the location were dated from 48,000 to 32,000 years before present, suggesting the possibility of a human presence tens of thousand of years prior to the arrival of the Clovis people in North America.
Tool use by non-humans is a phenomenon in which a non-human animal uses any kind of tool in order to achieve a goal such as acquiring food and water, grooming, combat, defence, communication, recreation or construction. Originally thought to be a skill possessed only by humans, some tool use requires a sophisticated level of cognition. There is considerable discussion about the definition of what constitutes a tool and therefore which behaviours can be considered true examples of tool use. A wide range of animals, including mammals, birds, fish, cephalopods, and insects, are considered to use tools.
Robust capuchin monkeys are capuchin monkeys in the genus Sapajus. Formerly, all capuchin monkeys were placed in the genus Cebus. Sapajus was erected in 2012 by Jessica Lynch Alfaro et al. to differentiate the robust (tufted) capuchin monkeys from the gracile capuchin monkeys, which remain in Cebus.
Gracile capuchin monkeys are capuchin monkeys in the genus Cebus. At one time all capuchin monkeys were included within the genus Cebus. In 2011, Jessica Lynch Alfaro et al. proposed splitting the genus between the robust capuchin monkeys, such as the tufted capuchin, and the gracile capuchins. The gracile capuchins retain the genus name Cebus, while the robust species have been transferred to Sapajus.
The crested capuchin or robust tufted capuchin is a species of robust capuchin monkey. It is endemic to Brazil. It was formerly considered a subspecies of the black capuchin but is now considered by some to be a separate species.
Azaras's capuchin or hooded capuchin is a species of robust capuchin. It occurs in eastern Paraguay, southeastern Bolivia, northern Argentina, and Brazil, at Mato Grosso do Sul and Mato Grosso states, in Pantanal. Its habitat consists of subtropical, humid, semi-deciduous, gallery forests and forested regions of the Pantanals. Formerly, it was considered a subspecies of black-striped capuchin, according to Groves (2005) with the name Cebus libidinosus paraguayanus, but Silva Jr. (2001) considered it a separated species. They are considered as frugivores-insectivores which means that their diet mainly consists of a variety of fruits, seeds, arthropods, frogs, small mammals, etc.
Social learning refers to learning that is facilitated by observation of, or interaction with, another animal or its products. Social learning has been observed in a variety of animal taxa, such as insects, fish, birds, reptiles, amphibians and mammals.
Primate archaeology is a field of research established in 2008 that combines research interests and foci from primatology and archaeology. The main aim of primate archaeology is to study behavior of extant and extinct primates and the associated material records. The discipline attempts to move beyond archaeology's anthropocentric perspective by placing the focus on both past and present primate tool use.
The Margarita Island capuchin, also known as the tufted Margarita Island capuchin or mono de margarita is a subspecies of the tufted capuchin that only resides in the Caribbean Sea on Margarita Island, Venezuela.
