The white-headed capuchin (Cebus capucinus) is a medium-sized New World monkey of the family Cebidae, subfamily Cebinae. It is also known as the white-faced capuchin or the white-throated capuchin. Information technology comes from the forests of Primal America. It also lives in the extreme northwestern part of South America. The white-headed Capuchin is important to pelting forests because of its role in dispersing seeds and pollen.
In recent years the species has become popular in North American media. It is a very intelligent monkey and has been trained to help paraplegic people.
The monkey is medium-sized. It can weigh upward to 3.9 kg (8.half dozen lb). The colour is mostly black but they accept a pink face. They also have white on the front part of the body. Information technology has a distinctive prehensile tail that is coiled up and is used to help back up the monkey on a branch.
In the wild, the white-headed capuchin can live in many different types of forest. They can eat many unlike types of food, like fruit, other plants, insects, and small vertebrates. It lives in troops (groups) that tin have more than than 20 animals, both males and females. It is noted for its tool use. They tin rub plants over their fur in using herbal medicine. They can also utilize tools as weapons and for getting food. The monkey has a maximum recorded age of over 54 years.

Taxonomy
Some regime consider this a fellow member of the subspecies Cebus capucinus imitator.
The white-headed Capuchin was originally described by Carolus Linnaeus in his 18th century work, Systema Naturae. It is a member of the family Cebidae. Information technology is office of the family of New World monkeys containing capuchin monkeys, squirrel monkeys, tamarins and marmosets. It is part of the genus Cebus. It is part of the C. capucinus species group. This group also includes the white-fronted capuchin, the weeper capuchin and the Kaapori capuchin.
Some scientists remember there are 3 subspecies of white-headed Capuchin:
- C. c. capucinus, from the southern part of the range in Ecuador, Colombia and eastern Panama
- C. c. imitator, from most of Nicaragua, Republic of costa rica and western Panama
- C. c. limitaneus, from Honduras and northern Nicaragua
But other scientists do not recognize any carve up subspecies.
Physical description
Like other monkeys of the Cebus group, the white-headed Capuchin is named subsequently the guild of Capuchin friars – the cowls worn by these friars looks like the monkey'south white fur.
The white-headed Capuchin has mostly black fur. It has white or yellow fur on the neck, pharynx, chest, shoulders, and upper arms. The confront is pink or a white-cream colour. The face can sometimes have marks like nighttime brows or dark fur patches. There is also an area of blackness fur on the summit of the caput.
Developed monkeys can reach a length of between 335 and 453 mm (13.2 and 17.8 in), excluding the tail. They can weight of upwardly to 3.9 kg (viii.6 lb). The tail is longer than the body. It tin be equally long equally 551 mm (21.7 in). Males are about 27% larger than females. The brain of a white-headed Capuchin is about 79.2 g (2.79 oz). It is larger than that of other large monkey species similar the Mantled Howler.
Behavior
The white-headed capuchin is a diurnal and arboreal animal. However, information technology does come up down to the basis more than oft than many other New Earth monkeys. It moves primarily by walking on all iv limbs. Information technology lives in troops, or groups, of upward to 40 monkeys (mean 16, range 4–40) and has a male/female adult sexual practice ratio of 0.71 on boilerplate (range 0.54–0.88). With rare exceptions, females spend their entire lives with their female kin. Males migrate to new social groups multiple times during the class of their lifetimes, migrating for the offset time between 20 months and 11 years of age. The median age of migration in the Santa Rosa population is 4.5 years. Males sometimes migrate solitary, just more often they drift in the visitor of other males who are often their kin. One of the unusual features of the kinship structure of the white-headed capuchin, relative to other primate species, is the loftier caste of relatedness within groups that results from the long tenures of alpha males who sire virtually of the offspring. Blastoff males have been known to go on their positions as long as 17 years in this species and this puts them in the unusual position of being available to sire the offspring of their daughters and granddaughters, who produce their first offspring at most six–7 years of age. Typically, nevertheless, alpha males do not breed with their own daughters, even though they do sire virtually all offspring produced by females unrelated to them. Those subordinate males who are allies of the alpha male in grouping defence are the males who sire the offspring of the alpha male'south daughters. The high degree to which alpha males monopolize matings results in an unusually big number of paternal half-siblings and full siblings in this species relative to other primate species.
Kinship is an important organizing factor in the structuring of female person-female social relationships. Particularly in larger groups, females preferentially associate with, groom, and provide coalitionary support to their matrilineally related female kin. They practice non exhibit a similar preference for their paternal half sisters, which may mean that they only are capable of recognizing kinship through the maternal line. Dominance rank is as well an important organizing factor, with females more than ofttimes grooming and associating with females who are closer to them in the say-so hierarchy. Female-female dyads groom far more than male person-female and male-male person dyads. Coalitionary aggression is mutual both amid males and females, and capuchins seem to have an excellent understanding of the brotherhood structure in their grouping. For example, when capuchins are fighting, they sensibly recruit help from someone who is both higher ranking than they are and as well improve friends with themselves than with their opponent.
Female person capuchins have linear potency hierarchies. In contrast to many Old World monkeys such every bit macaques, in which females socially inherit the rank merely beneath their mothers and just above their adjacent oldest sisters, capuchins exercise non take a highly anticipated ranking within their matrilines. Males are typically dominant to females. The alpha male is ever easy to discern, but there are sometimes ambiguous rankings among subordinate males. Male-male relationships are tense, and affiliation between males is typically expressed past resting in contact, playing, or not-conceptive sex rather than by grooming. Males cooperate in coalitions confronting potential predators, and too in defense of the grouping confronting other males. Occasionally male coalitionary aggression becomes then violent that males are killed, especially if they are encountered roaming the forest unaccompanied past allies. Because aggression from other male capuchins is the leading crusade of death (aside from poaching by humans, where there is contact between humans and capuchins), male allies are disquisitional for self-defence force during migration, and to assist in taking over other groups. Male emigration to a new troop typically occurs about every 4 years, and then most males are in constant danger of having to defend themselves against other groups of males.
Interactions between groups
White-faced capuchin troops occupy home ranges of between 32 and 86 hectares (79 and 213 acres). They travel between 1 and 3 kilometres (0.62 and 1.86 mi) daily, averaging ii kilometres (1.2 mi) per day. Although they engage in activity that has been described equally "territorial", more recent research indicates that White-faced capuchin troops tend to behave aggressively to other White-faced capuchin troops regardless of where they meet, and the aggression is not necessarily intended to exclude the other troops from a specific home range.
Home ranges overlap extensively, then groups are not territorial in the strictest sense of the word. Mayhap considering of the intensity of male-male competition. Typically, males are the primary participants in aggressive intergroup encounters, and it seems likely that males are defending access to the females in their groups. Alpha males, who accept the largest reproductive stake in the grouping, participate at a higher rate than subordinate males. Groups with more males have an advantage over groups with fewer males, but the location of the encounter inside the home range matters equally well; smaller groups defeat larger groups when the competition occurs in the core or eye area of the smaller group'south dwelling range.
Interspecific interactions
The white-headed capuchin sometimes interacts with other sympatric monkey species. White-headed capuchins sometimes travel with and even groom Geoffroy'south Spider Monkeys. All the same, ambitious interactions betwixt the capuchins and spider monkeys also occur. Interactions betwixt the white-headed capuchin and mantled howler are infrequent, and sometimes issue in the capuchins threatening the larger howlers. Withal, affiliative associations between the capuchins and howlers do sometimes occur, more often than not involving juveniles playing together.
Although South American capuchin species often travel with and feed together with squirrel monkeys, the white-headed capuchin only rarely associates with the Central American squirrel monkey. This appears to be related to the patchier, more dispersed distribution of nutrient resources in Cardinal America and the fact that there is less dietary overlap between the Central American squirrel monkey and the white-headed capuchin than betwixt their South American counterparts. Therefore, there is less do good to the Central American squirrel monkey in associating with the white-headed capuchin in order to exploit the capuchin's noesis of food resources distribution. In addition, compared to their South American counterparts, male white-headed capuchins are relatively more alarm to rival males than to predators, reducing the predator detection benefits that the Central American squirrel monkey receives from associating with the white-headed capuchin compared to its Southward American counterparts. Since the squirrel monkeys generally initiate interactions with the capuchins in South America, the fact that similar associations would impose higher foraging costs and impart fewer predator detection benefits to the Primal American squirrel monkey leads to fewer associations with the white-headed capuchin.
Several not-primate animal species tend to follow troops of White-faced Monkeys or are otherwise attracted past their presence. white-lipped peccaries and common agoutis are attracted by feeding white-headed capuchins, looking for fruit that the capuchins drib. Several species of bird are also known to follow white-headed capuchins looking for food. These include the double-toothed kite, the white hawk and the sharp-shinned hawk.
Diet
The white-headed capuchin is an omnivore. Its primary foods are fruit and insects. It forages at all levels of the wood, and besides forages on the ground. Methods for finding food include stripping bawl off of trees, searching through leaf litter, breaking dead tree branches, rolling over rocks, and using stones as anvils to crack hard fruits. Its prehensile tail assists with feeding, helping back up the monkey when foraging for food below the branches.
Fruit can brand upwardly betwixt 50% and 67% or more of the capuchin's nutrition. In ane study in Panama, white-headed capuchins ate 95 different fruit species. Amongst its favorite fruits are figs from the family Moraceae, mangos and related fruits from the family Anacardiaceae, the bean-similar fruits from the family Leguminosae and fruits from the family Rubiaceae. It generally only eats ripe fruit, testing for ripeness by smelling, tasting and prodding the fruit. It typically eats only the pulp and juice, spitting out the seeds and fibers. Other found thing eaten includes flowers, young leaves, seeds of certain plants, and bromeliads. Information technology also uses the bromelids as a h2o source, drinking the h2o that gets trapped inside. In Carara National Park the capuchins accept a varied diet in addition to the in a higher place of banana fruits and flowers, heliconia seeds, huevos de caballo fruits and anacardiaceae stems.
Insect casualty eaten includes beetle larvae, butterfly and moth caterpillars, ants, wasps, and pismire and wasp larvae. It also eats larger prey, such every bit birds, bird eggs, frogs, lizards, crabs, mollusks and pocket-sized mammals. The population in Guanacaste, Republic of costa rica in particular is noted for hunting squirrels, magpies, White-crowned Parrots and baby coatis. The corporeality of vertebrate prey eaten varies past troop. Even neighboring troops can evidence meaning differences in their diets.
The diet can vary between the rainy and dry out season. For example, in Guanacaste, Costa Rica the white-headed capuchin can swallow a broad variety of fruits too as caterpillars in the early rainy flavour (June to November). Simply during the dry flavour, only figs and a few other types of fruit are bachelor. During the dry season, chitinous insects, ant and wasp larvae and vertebrates become a particularly important role of the white-headed capuchin'south diet. Access to water tin too go an consequence during the dry flavor. The white-headed capuchin likes to drink daily, so in forests where water holes dry upwardly during the dry flavor, there tin can be competition between troops over access to the remaining water holes.
Tool use
Capuchins are considered among the nearly intelligent of the New World monkeys; they have been the subject field of many studies on behaviour and intelligence. The capuchins' intelligence is thought to exist an adaptation to support their feeding habits; they rely on ephemeral nutrient sources which may be hard to find. In one particular written report conducted in 2007, capuchins were found to exist among the 10 most intelligent primates, second to spider monkeys amid New Earth monkeys.
The white-headed capuchin is known to rub parts of certain plants into their fur. Plants used in this mode include citrus fruits, vines of the genera Piper and Clematis, monkey comb (genus Sloanea), impaired pikestaff and custard apple. Ants and millipedes are besides used in this style. Information technology is not definitively known what this fur rubbing is for, just this may deter parasites such every bit ticks and insects, or information technology may serve equally a fungicide or bactericide or anti-inflammatory agent. Alternatively, information technology may be a grade of scent marking.
The white-headed capuchin also uses tools in other ways. It has been known to beat snakes with sticks in society to protect itself or to get the serpent to release an baby. In captivity, it has been known to use tools to get to nutrient or to defend itself, and once a white-headed capuchin used a squirrel monkey as a projectile, hurling it at a human observer. Some populations also utilize trees or other hard surfaces equally anvils in order to crack mollusks. And it sometimes uses sticks equally probes to explore openings.
Though the white-headed capuchin tin utilise tools in many dissimilar ways, information technology does not use tools as often as the robust capuchins (Sapajus) do, and male person capucins tend to apply tools more than than female capuchins practice. Scientists recollect animals learn to use tools if food is hard to get and if there are non many predators around, and this seems to exist true with different groups of white-faced capuchins.
The white-headed capuchin's intelligence and ability to use tools allows them to be trained to assist paraplegics. Other species of capuchin monkeys are likewise trained in this mode. White-headed capuchins can likewise be trained for roles on tv set and movies, such equally Marcel on the idiot box serial Friends. They were likewise traditionally used as organ grinder monkeys.
Communication
The white-headed capuchin is noisy. Loud calls, such equally barks and coughs, are used to communicate threat warnings, and softer calls, such as squeals, are used in intimate soapbox. Different types of threats, such every bit a threat from a terrestrial animal versus a threat from a bird, invoke unlike vocalizations. Facial expressions and scent are as well important to communication. It sometimes engages in a practice known as "urine washing", in which the monkey rubs urine on its feet. The verbal purpose of this practice is unknown, but information technology may be a class of olfactory signal.
Reproduction
The white-headed Capuchin has a polygamous mating organization. The male tin can mate with many females. The dominant male usually fathers well-nigh of the immature. The ascendant male is more likely to mate when the female is the most fertile. Dominant males avoid breeding with their own daughters who are members of the troop. This is rare among New Globe monkeys.
The gestation menses is five to 6 months. A single young is built-in. Twins tin sometimes exist built-in. Most births happen during the dry out season. Information technology is from December to April. The babe is carried on the mother's dorsum for about half dozen weeks. After 4 to 5 weeks the baby can get off from its mother's back for a short flow of time. At iii months it can movement effectually by itself. Some babies will be mostly independent before.
Weaning happens betwixt six and 12 months. While the mother rests, the babies spend nigh of their time foraging or playing. They tin can do that on their own or with other babies. Capuchins engage in high levels of alloparenting, in which monkeys other than the female parent help care for the infant. Males and females engage in alloparenting.
Like other Capuchin monkeys, the white-headed Capuchin matures slowly. Sexual maturity is reached at iii years. On boilerplate, females give nascency for the first time at seven years old and give birth every 26 months. Males reach maturity at 10 years old. The white-headed Capuchin has a long life span. The maximum recorded life span in captivity is over 54 years.
Habitats
White-headed capuchin at Frío River, Costa Rica
The white-headed Capuchin lives in Central America and a pocket-size part of South America. In Central America, its home includes Republic of honduras, Nicaragua, Costa rica and Panama. It has also been seen in eastern Guatemala and southern Belize, but these reports are unconfirmed. In Southward America the white-headed Capuchin lives in the extreme north-western part between the Pacific Ocean and the Andes Mountains in Colombia and Republic of ecuador. It is among the nigh commonly seen monkeys in Fundamental America'southward national parks, such as Manuel Antonio National Park, Corcovado National Park, Santa Rosa National Park and Soberania National Park.
Information technology is very common in Costa Rica and Panama, just the monkey has been thrown out from Honduras and much of Nicaragua. Many Honduran Capuchin monkeys were captured and relocated to the island of Roatán, and many Nicaraguan Capuchin monkeys were captured and relocated to the island of Ometepe.
Information technology is found in many unlike types of forest, including evergreen and deciduous forests, dry and moist forests, and mangrove and montane forests. The monkey appears to ilke primary or advanced secondary forests.
