Allogrooming and scent marking have been studied in S. mystax societies. Allogrooming or social grooming is commonly observed in mustached tamarins, but it is not practiced equally by all members of a troop. In one study by Heymann (1996), an adult male contributed 70% of all grooming observed in a group, without bias to any one of the other members in his troop. The reasons for this asymmetry are not well-characterized but may be attributed to differences in social standing or competition for reproductive success. As mentioned above, breeding females may employ social grooming as a way of encouraging other members in her troop to stay to assist in parental care duties.
The use of scent marking for territorial demarcation is variable among Saguinus species. In both wild and captive S. mystax, there is little evidence for the use of scent marking in territorial defense.
Scent marking functions prominently in intra-group communication and female mustached tamarins are more likely to engage in scent marking behavior, compared to males. On the contrary, male mustached tamarins are more likely to respond to scent marks of the opposite sex, which may be related to mate selection. Mustached tamarins do not engage in "collective scent marking" or allomarking, unlike in S. fuscicollis.
The rates of scent marking by mustached tamarins are directly proportional to the duration of occupation of areas by the troop. Intense scent marking in more frequented areas enhances the effectiveness of olfactory communication between members of the same troop.
Vocalization has also been demonstrated to be a form of communication in S. mystax, such as in situations where a mustached tamarin becomes separated from its troop. According to Snowdon and Hodun (1985, p. 211), "The long-call structure of the moustached tamarin is similar to that of its sympatric tamarin species, saddleback tamarins. In both species the calls last 2 to 3 seconds, consist of several short, frequency-modulated syllables, and has a frequency range of 8 to 12 kHz". The same study also noted that "nonbreeding adult females gave fewer calls" and they were also slower to make the first long call upon separation. This could reflect "the relatively low status of nonreproductive mature females" (p. 211) in their troop, which is usually centered on a single breeding female. Members of a troop are able to recognize members of their troops by responding to long calls from separated members. This ability to distinguish individual members suggests that a S. mystax troop in the wild is able to maintain its integrity by ensuring that all members are accounted for.
Early morning vocalizations and subsequent coordinated movement patterns within mixed-species troops of mustached tamarins and saddle-back tamarins are also crucial in maintaining group integrity on a daily basis.

Genetic analysis supports the division of tamarin taxa into small-bodied and large-bodied clades (Matauschek et al., 2011, p. 564), of which S. mystax is a member of the large-bodied clade. Molecular phylogenetic evidence also supports the “phyletic dwarfism” hypothesis in Callitrichinae, which is "defined as a gradient in morphological size partially correlated with evolutionary time" (Perelman et al., 2011, p. 4). In this case, Saguinus is the first to diverge, followed by the remaining callitrichines in order of decreasing body size. Within Saguinus, phylogenetic analysis of mitochrondrial DNA has demonstrated that Saguinus labiatus is the closest relative of S. mystax, with the two taxa diverging about 1.15 mya.
Mustached tamarins are on the least concern list of animals on The IUCN Red List of Threatened Species (last assessed in 2008). Populations of wild mustached tamarins have been noted to be stable, although habitat destruction remains a threat to species living in the Amazonian rainforest.
The effects of agriculture on S. mystax populations in Peru have been studied. Populations recovered and even exceeded pre-agricultural numbers due to "increased reproductive rate, early breeding, and reduced infant mortality", while "immigration seemed to play a minor role" (Ramirez, 1984, p. 258).
US Federal List: no special status
CITES: appendix ii
IUCN Red List of Threatened Species: least concern
Although commensally associated with human communities, there is no evidence for adverse economic effects on humans.
Saguinus mystax, like other tamarin species, has been used extensively in biomedical research, e.g., in the development of the hepatitis A vaccine.
Positive Impacts: research and education
Mustached tamarins play an important ecological role in their habitat by dispersing seeds of plant species in primary and secondary rain forest, and thus indirectly impact forest regeneration and maintenance.
As mustached tamarins are opportunistic feeders and are able to explore many kinds of plant resources, they are able to disperse a great variety of seed species.
Due to their small size, there is a limit to the size of seeds that they can disperse. Seasonal changes in diet, sleeping and resting patterns, and variation in foraging behavior and migration may also affect their contribution to seed dispersal in the rainforest.
On a negative note, mustached tamarins have been observed to be highly destructive in their nectar-feeding activities but the widespread ecological impact of this has not been demonstrated.
Mustached tamarins that foraged near human settlements were found to have higher prevalence of a primate parasite, Prosthenorchis elegans. However, in the same study by Wentz et al. (2010), mustached tamarins were not found to be infected by human parasites even though they lived in close proximity to human communities with high rates of infestation of nematodes such as Ascaris lumbricoides and hookworms.
Ecosystem Impact: disperses seeds
Mutualist Species:
Commensal/Parasitic Species:
Being frugivorous-insectivorous, mustached tamarins feed on fruits, flowers, and nectar, insects, and plant exudates. Food sources like gums and soil appear to supplement nutrients and minerals lacking in their main diet of fruits and insects.
Mustached tamarins typically only feed on a small number of plant species in their home range. However, feeding trees are numerous and scattered throughout their home range. Feeding trees are usually continuously fruiting and produce a small amount of fruits daily, hence mustached tamarins may visit the same trees regularly over a span of several months to exploit the resources.
In a group of mustached tamarins in northeastern Peru, up to a third of feeding time was spent feeding on nectar from Symphonia globulifera in the dry season. Mustached tamarins concentrated their foraging efforts on trees that yielded more nectar, despite having to travel greater distances between feeding sessions in some cases. Therefore, proximity of feeding trees from one another did not predict foraging patterns, as mustached tamarins preferentially chose feeding trees that allowed them to feed for longer periods of time instead of trees that were closer and would thus minimize traveling time from one tree to another.
Although feeding trees are typically scattered throughout their home range, mustached tamarins are able to remember the locations of the important feeding trees to minimize efforts in foraging. The use of spatial memory and learning in foraging are important because they provide "an efficient means of exploiting a widely scattered set of predictable feeding sites" (Garber, 1989, p. 212).
Gum feeding is highly seasonal, but it is a major dietary staple during dry and early wet seasons when other food sources are scarce. Furthermore, gum exudates balance mineral intake, which will otherwise suffer from the effects of a low-calcium and high-phosphorus insectivorous diet.
Since mustached tamarins lack the dental specialization to gouge holes into tree bark, gum feeding is "dependent principally on either natural weathering of the bark or on the parasitic activity of woodboring insects, or both" (Garber, 1992, p. 471).
Heymann and Smith (1999) found that Saguinus mystax concentrated gum feeding in the afternoon. They hypothesized that this may be "a behavioral strategy to prolong the time that the gums are retained in the gastrointestinal tract" (p. 468). Prolonged passage allows for better digestion and more complete microbial fermentation of the substrates. This in turn yields nutritional benefits while providing these small animals with a means to generate heat during the night via the fermentation process.
Garber (1992) described mustached tamarins as exhibiting "a highly opportunistic foraging pattern," with "seasonal exudate feeding, occasional trunk foraging patterns, and small-branch fruit and insect feeding" (p. 471).
The main vertebrate prey for mustached tamarins includes "katydids (Tettigoniidae, Orthoptera), stick grasshoppers (Proscopiidae, Orthoptera), and spiders (Araneidae), although lizards (Squamata) and frogs (Anura) were also taken" (Smith, 2000, p. 315). Mustached tamarins also feed on nestling birds, albeit less frequently. They forage for prey at higher levels within the forest strata than Saguinus fuscicollis (average of 8.84 m vs. 1.50 m; Smith 2000), and also capture most prey from slender and horizontal substrates.

Typical lifespan
Status: captivity: >20 (high) years.
Mustached tamarins, being callitrichines, have distinguishing features that set them apart from other New World monkeys. These include their diminutive body size and the presence of claw-like nails on all digits except the hallux. Mustached tamarins have also lost both their upper and lower 3rd molars and the hypocones on their upper molars. The dental formula is 2.1.3.2 / 2.1.3.2. Tamarins have spatulate incisors that are shorter than their canines, unlike marmosets which have incisors and canines of more similar size. The labial and lingual sides of their incisors are also thickened with enamel. Mustached tamarins have jet black pelage on their body and tail and a characteristic white stripe on their upper lip, which gives the appearance of a "white mustache." Mustached tamarins do not have prehensile tails.
Mustached tamarins do not exhibit sexual dimorphism and there are only minor differences in body and canine size between males and females. On average, adult male mustached tamarins weigh 491 ± 23.0 g and measure 61.2 ± 31.2 cm (n=95), whereas adult females weigh 511.0 ± 49.0 g and measure 62.0 ± 29.0 cm (n=80).
According to Cesar and Bicca-Marques (1999), feeding behaviors are correlated with the relative size and shape of hands in callitrichines. Mixed-species groups of tamarins are observed to form only between species that have different foraging behavior, which reduces direct competition. Consequently, due to the specialization conferred by hand morphology, species with dissimilar hand shapes are usually found in association with each other in such mixed-species groups. This is the case in the mixed-species groups of mustached tamarins and saddle-back tamarins. Saguinus mystax captures exposed insects on branches and thus has evolved relatively wide and short hands, as opposed to saddle-back tamarins, which have made use of longer and more slender appendages to manipulate openings in tree trunks and other substrates to search for insect prey.

Average mass: 501 g.
Range length: 30 to 92.4 cm.
Average length: 61.6 cm.
Other Physical Features: endothermic ; homoiothermic; bilateral symmetry
Sexual Dimorphism: sexes alike
Due to their small size, mustached tamarins are vulnerable to predation by a large number of terrestrial predators, such as tayras (Eira barbara), ocelots (Leopardus pardalis), and jaguarundis (Puma yagouaroundi). Large snakes like Boa constrictor and birds of prey are also important predators.
Cooperative defense against predators was observed in a tribe of mustached tamarins in northeastern Peru. Members of this tribe successfully rescued a mustached tamarin that was being attacked by a Boa constrictor by counter-attacking the predator. The tribe subsequently avoided low heights for a week after the attack, as further deterrence to attacks by snakes.
In general, mustached tamarins counter predators by avoiding attracting attention. Mustached tamarins are camouflaged in densely foliated areas and they carefully select resting and sleeping sites that have lower chances of being exposed. They may also choose resting sites that are physically isolated from surrounding vegetation, as this would increase the likelihood of them being able to detect approaching predators.
Known Predators:
Anti-predator Adaptations: aposematic ; cryptic
Mustached tamarins usually associate in stable troops, which vary widely in size. For example, the mean group size was found to be 6 to 7 individuals per group in two studies (Garber et al., 1993; Löttker et al., 2004), with a range of 4 to 11 individuals in each group.
The reproductive strategy of S. mystax is described as polyandrous or polygynous. Each group is typically centered on one breeding female, which is usually also the oldest female. Despite the lack of breeding opportunities, adult non-breeding females may continue to persist in the group, and may ascend to breeding female status in the event of death or illness of the current breeding female.
A study by Löttker et al (2007) suggests that breeding females use social grooming as incentive to induce adult males and non-breeding offspring to stay in the group as helpers to care for their young.
Adult mustached tamarins live in highly tolerant and cooperative societies. Garber (1997) estimated that the frequency of cooperative to aggressive acts between adult mustached tamarins was 52:1. Intragroup sexual aggression between male mustached tamarins is exceedingly rare, but mate guarding may be practiced by the dominant breeding adult male during the breeding female’s most fertile periods.
Male mustached tamarins may compete for reproductive success via sperm competition and other physiological mechanisms. For example, testes volume in males within a group varied greatly among individuals and this could directly impact reproductive viability of males.
Despite a polyandrous mating system and seemingly a lack of evidence of strong competition or aggression over breeding opportunities, a genetic analysis of paternity in mustached tamarins revealed that 67 to 100% of S. mystax infants in a troop were fathered by the same adult male. Genetic relatedness within a troop is high but both non-related and related adults can co-exist in a troop. There is a need for a better understanding of the critical factors that govern the observed reproductive bias among adult S. mystax males.
Mating System: polyandrous ; polygynous ; polygynandrous (promiscuous) ; cooperative breeder
Mustached tamarins have characteristic twinned births, with an annual birth peak from November through March. Some S. mystax troops experience 2 birthing cycles, from June to October and in February and March.
Spatio-genetic analysis of a population of mustached tamarins in Peru by Huck et al. (2007) revealed variable genetic relatedness within a troop. Migration is common among male and female mustached tamarins, but females are often required to travel for longer distances than males before settling down with a new troop due to scarce breeding opportunities in a polyandrous mating society. Matings are generally between non-closely related partners, hence the degree of inbreeding is reduced.

Maternal infanticide, while rare, has been documented twice in Saguinus species, in S. mystax by Culot et al. (2011) and S. fuscicollis by Herrera et al. (2000). In both cases, infanticides occurred under circumstances of low availability of helpers (2 to 3 male helpers compared to 4 to 5 helpers at other times) and presence of more than 1 breeding female in the troop. Both of these factors lower the likelihood of obtaining sufficient care for the infant within the group.
The single most important determinant of maternal infanticide could be the mother’s perception of low probability of survival of her infant in the group, which is directly caused by external factors in the troops, such as low helper availability. Low helper availability or competition for care with infants from another breeding female in the same troop greatly reduces the chances of survival for infant mustached tamarins. Maternal infanticide may thus represent a strategy to maximize efforts that go into ensuring survival of infants. On the contrary, infanticide of unrelated infant tamarins by male mustached tamarins, which is usually attributed to sexual selection pressures, has never been observed in Saguinus. Males do not gain reproductive advantages from infanticide, as infant mortality has minimum effect on the mother’s fertility status. Female mustached tamarins remain reproductively viable during nursing of their young.
Due to the cooperative breeding behavior of S. mystax, the number of helpers available in a group to care for the young has a strong influence on the survival of infant tamarins (Garber, 1997).
Birth intervals were also shorter during the periods when infanticide occurred (1 to 2.5 months). In Saguinus fuscicollis, which also practices cooperative breeding like S. mystax, the optimal birth spacing is 3 months, so as to allow for efficient care of the young. Shorter birth intervals increase the burden on the troop to care for the young, and this effectively reduces the likelihood of providing adequate care for all of them.
Although not demonstrated in S. mystax, care and transport of infants results in significant personal costs for small-sized mustached tamarins. Loss of body mass of carriers of infants has been demonstrated in wild and captive Saguinus oedipus. Cooperative breeding allows the costs of caring for the young to be distributed to other members of a troop to a certain extent, and carriage of infant mustached tamarins is not restricted to certain members of a troop, as members usually take turns in transporting the young when foraging.

Tamarín bělovousý (Saguinus mystax) je druh opic, zástupce čeledi kosmanovitých (Callitrichidae) vyskytující se v Jižní Americe.
Žije v tropických deštných lesích centrální Amazonie, konkrétně na území severního Peru a západní Brazílie. Tvoří rodinné skupiny o čtyřech až jedenácti jedincích. Jejich součástí je jedna samice, která se rozmnožuje. Po březosti o délce 145 dní se zpravidla rodí dvě mláďata. O ta se následně stará zejména otec. Matka mláďata pouze kojí.[2]
Živí se mízou, nektarem, plody a bezobratlými.[3]
Včetně ocasu dosahuje délky až 61 cm. Váží přibližně půl kilogramu.[3] Dokáží se pohybovat velmi rychle, přičemž většinu života tráví na větvích.[2]
Tamarín bělovousý je jednou z nejvzácněji chovaných drápkatých opic.[2] V Evropě je k vidění jen v pěti zoo. Kromě německého Magdeburgu se jedná o čtyři české zoo[4]:
Svého času (před rokem 2015) byla Zoo Praha dokonce jednou ze dvou zoo v Evropě s tímto druhem.[2]
Chov v Zoo Praha započal roku 2008. Tehdy byla přivezena samice ze švýcarského Curychu. O čtyři později byl získán pár. Prvoodchov v historii českých zoo byl zaznamenán 17. 6. 2017.[2][5]
Druh je k vidění v pavilonu goril v dolní části zoo.[2]

Der Schnurrbarttamarin (Saguinus mystax) ist eine Primatenart aus der Familie der Krallenaffen (Callitrichidae).
Das Fell der Schnurrbarttamarine ist vorwiegend dunkelbraun bis schwarz gefärbt. Herausragend ist jedoch die weiße Mundpartie mit dem namensgebenden Schnurrbart. Die Tiere erreichen eine Kopfrumpflänge von 23 bis 28 Zentimeter und eine Schwanzlänge von 37 bis 44 Zentimeter. Ihr Gewicht beträgt 450 bis 600 Gramm. Wie bei allen Krallenaffen befinden sich an den Fingern und Zehen (mit Ausnahme der Großzehe) Krallen statt Nägeln.
Schurrbarttamarine sind im westlichen Amazonasbecken in Südamerika beheimatet. Ihr Verbreitungsgebiet liegt südlich des Amazonas und westlich des Rio Purus im östlichen Peru und im westlichen Brasilien (Bundesstaaten Amazonas und Acre). Lebensraum dieser Art sind Regenwälder, wobei sie vorwiegend in mit dichtem Unterholz bestandenen Sekundärwäldern oder an den Waldrändern lebt.
Diese Primaten sind tagaktive Baumbewohner. Sie bewegen sich auf allen vieren fort und überwinden größere Distanzen auch springend, dank ihrer Krallen können sie auch gut an Baumstämmen entlangklettern. Sie halten sich dabei meist rund 10 Meter über dem Boden auf. Häufig vergesellschaften sie sich mit Braunrückentamarinen.
Sie leben in Gruppen von 2 bis 10 Tieren, die Gruppen setzen sich aus mehreren Weibchen, mehreren Männchen und dem dazugehörigen Nachwuchs zusammen. Innerhalb der Gruppe ist das Sozialverhalten stark ausgeprägt, aggressives Verhalten ist selten. Gegenseitige Fellpflege ist häufig zu beobachten. Sie bewohnen feste Reviere von 35 bis 40 Hektar.
Schnurrbarttamarine sind Allesfresser, die sowohl Früchte und andere Pflanzenteile als auch Spinnen, Insekten, kleine Wirbeltiere und Vogeleier zu sich nehmen. Die Tiere verbreiten die Samen der aufgenommenen Früchte weiter. Nach Untersuchungen im nordöstlichen Peru sind Transportwege von bis zu 650 Meter nachweisbar, wobei über 90 % der Samen in einem Abstand von bis zu 350 Meter vom Elternbaum wieder ausgeschieden werden. Das hat zur Folge, dass Samen auch entwaldete Sekundärflächen erreichen, womit die Schnurrbarttamarine indirekt zur Wiederbewaldung devastierter Flächen beitragen. Zu den häufig transportierten Samen gehören unter anderem jene der Gattungen Parkia, Inga, Dicranostyles und Paullinia. Rund 18,6 % der ausgeschiedenen Samen keimen und überleben das erste Jahr.[1]
Wie bei allen Tamarinen pflanzt sich nur das dominante Weibchen der Gruppe fort und paart sich mit allen Männchen der Gruppe, ein unter Säugetieren seltenes Phänomen, das als Polyandrie bezeichnet wird. Nach einer Tragezeit von 140 bis 145 Tagen bringt das Weibchen meist zweieiige Zwillinge zur Welt. Diese sind relativ und groß und wiegen rund 25 % der Mutter. Die anderen Gruppenmitglieder, auch die Männchen, kümmern sich intensiv um die Jungen, sie tragen sie und beschäftigen sich mit ihnen und übergeben sie der Mutter nur zum Säugen.
Die Jungtiere beginnen nach einem Monat mit der Nahrungsaufnahme und werden mit zwei bis drei Monaten endgültig entwöhnt. Die Geschlechtsreife erreichen sie mit 16 bis 20 Monaten.
Der Schnurrbarttamarin bildet zusammen mit dem Rotbauchtamarin und dem Kaiserschnurrbarttamarin die mystax-Gruppe innerhalb der Gattung der Tamarine.
Es werden drei Unterarten unterschieden, die Nominatform Saguinus mystax mystax westlich des Rio Juruá, S. m. pluto im Osten des Verbreitungsgebietes und der Rotkappentamarin (Saguinus mystax pileatus), der zwischen den beiden anderen Unterarten vorkommt. Letzterer unterscheidet sich durch eine rostbraune Kopfkappe und eine etwas hellere Fellfarbe von den beiden anderen Unterarten, die sich stark ähneln. Er wurde deshalb zwischenzeitlich als eigenständige Art angesehen, im 2013 erschienenen Primatenband des Handbook of the Mammals of the World aber wieder dem Schnurrbarttamarin als Unterart zugeordnet.[2]
Der Schnurrbarttamarin (Saguinus mystax) ist eine Primatenart aus der Familie der Krallenaffen (Callitrichidae).
The moustached tamarin (Saguinus mystax) is a New World monkey and a species of tamarin. The moustached tamarin is named for the lack of coloring in the facial hair surrounding their mouth, appearing similar to a moustache. As with all New World monkeys, the moustached tamarin is found only in areas of Central and South America.
There are 3 subspecies of the moustached tamarin:
Moustached tamarins have a lifespan of about 20 years. They are small, weighing 500 to 600 grams, and range in length from 30 to 92 centimeters, with adult females larger than males.[3][4]
Moustached tamarin monkeys are characterized by white, curly hair around their mouth, similar to a moustache.[5] Their face is flat with almond-like shaped eyes.[5] Their ears are furry and large, and they have long, silky, body hair.[5] They have a brownish-black body with a white moustache and white nose. They have tegula, which are claw-like nails, on each digit except their big toe. These claws allow them to easily cling to trees while they feed. They have conical or spatulate incisors, which are used for cutting food, and are smaller than their canines.[4] The lingual and labial sides of their incisors have a thick layer of enamel. Unlike most New World Monkeys, the moustached tamarin monkey has non-opposable thumbs and lacks a prehensile tail.[5]
Heterozygous females, which make up about 60% of the female tamarin population, have trichromatic vision, while the remaining moustached tamarin population have dichromatic vision.[3] Trichromatic vision is the capacity to see a broader range of color due to the presence of three color receptors in the retina, at the back of the eye, allowing them to distinguish between greens, blues and reds.[3] Humans, as well as most species of Old World Monkeys, have trichromatic visual abilities; however, some female New World monkeys do as well. Dichromatic vision is a form of color vision in which only two of the primary colors are perceived.[3] Trichromatic vision is an evolutionary adaptation that enables females to more easily find and identify fruit. Color vision is a contributing factor for leadership selection in troops.
Moustached tamarins are inhabitants of tropical rainforests in Brazil, Bolivia and Peru.[4] They live in arid, upland forests in the Amazonian lowland, mostly occupying higher tree branches. The home range of moustached tamarins is between 25 and 50 hectares.[3]
Moustached tamarins are omnivorous, frugivorous and insectivorous. Their diet mainly consists of fruits, nectar, gum exudates, invertebrates and small vertebrates. Invertebrates include katydids, stick grasshoppers, and spiders.[4] Vertebrates include lizards and frogs. Gum feeding is seasonal, however it is a dietary staple during dry and early wet seasons when other resources are scarce. Exudates supplement nutrients and balance mineral intake; which prevent the species from experiencing a range of detrimental effects from a low-calcium and high-phosphorus insectivorous diet. They display a highly opportunistic foraging pattern, and the ratio and variety of their comestibles depend on the availability in their geographical location. Moustached tamarins select trees by the amount of nectar they yield, rather than proximity to their home range. This higher volume of nectar makes the chosen trees more reliable because it allows them to feed for longer periods. Their remarkable spatial memory allows them to quickly recall the location of fruiting trees. Spatial memory is vital because it aids in the exploitation of a widely scattered set of feeding sites and minimizes effort in foraging.[4]
The moustached tamarin monkey is a crucial seed disperser for many plant species as a result of their diverse diet. They spread the seeds of fruits they ingest, indirectly impacting forest regeneration and maintenance. They are opportunistic feeders, utilizing a wide range of plant resources, allowing them to disperse a variety of seed species, providing significant benefit to their ecosystem.[4]
Moustached tamarins are territorial, however, they sometimes join with groups of brown-mantled tamarins (Saguinus fuscicollis) and Geoffroy's saddle-back tamarin (Leontocebus nigrifrons).[3] These species can cohabit because they have varying locomotor types, hunting techniques, support preference, food selection, and reside in different strata of their forest habitat.[4] The brown-mantled tamarin and the moustached tamarin do not compete for the same resources. Sharing territory with another species facilitates predator avoidance, increasing survival chances for both groups. Having more eyes and ears provides greater protection.
Moustached tamarins are arboreal, diurnal,[3] and precocial. Tamarins walk and run on all fours, similar to squirrels and use their claws for stability. The moustached tamarin monkey exercises three types of locomotion. Symmetrical quadrupedalism is the most frequently used locomotion type, followed by asymmetric quadrupedalism, and leaping.[4] The kind of leap depends on the layer of the forest they occupy. In the lower canopy “trunk-to-trunk” leaps are performed.[3] These are jumps that are short and quick, only reaching a length of 1 to 2 meters.[3] While standing on a medium or large-sized trunk, they propel themselves into the air and land on their front limbs on another trunk. They perform “bounding” leaps which allow them to cross between discontinuous trees, extending their legs farther out, reaching up to 2 meters.[3] In the high canopy, they perform “acrobatic” leaps. These are longer leaps, reaching 5 meters or more, used to travel between treetops.[3] While in the air, they use their tail to decelerate their body before landing on the crown of a nearby tree.
Moustached tamarin monkeys select densely foliated areas for resting and sleeping to best camouflage themselves because their small size makes them an easy target. Their main tactic is to avoid predation by attracting as little attention as possible. Their predators include eagles and other birds of prey, snakes, tayras, jaguarundis, ocelots and other wild cats.[4]
Social grooming can be used to develop bonds. The moustached tamarins use their claws to detangle and comb one another’s hair and remove parasites and dirt with their teeth and tongue.[3] Social grooming is not equally exercised by members and the amount of grooming services given and received depends on the social position of the individual.
Scent marking is used to identify territory boundaries and to communicate with others.[3] Females practice scent marking more frequently than males because it is also used in mate selection.[3] The three types of scent marking are circumanal marking, suprapubic marking and sternal marking.[5] Circumanal marking is the most commonly used type of scent marking.
Visual communication includes facial expressions, gestures, tonguing, and head-flicking. Tonguing is when a moustached tamarin moves its tongue across its lips. Head-flicking is when a moustached tamarin rapidly moves its head in an upward motion. Tonguing and head-flicking often co-occur and are used to communicate recognition, curiosity or anger.
Group sizes are usually 4-8 individuals, excluding infants, and each group usually contains 1 or 2 adult females.[3] However, groups have been observed to reach up to 15 individuals and solitary individuals have been encountered. Routinely, groups of moustached tamarins leave early in the morning to forage for food. They do not feed simultaneously. One of the adults positions themselves near the feeding site and scans the surroundings for predators to protect the group during mealtimes. They then retire at night in highly foliated areas to protect themselves from predators during slumber.[3]
There is often strife between neighboring groups of moustached tamarins due to limited food resources, especially near large feeding trees.[3] Vocal battles can arise, with long calls that consist of short syllables at a high frequency.[6] This type of conflict occurs between groups that are 25 meters or more apart.[6] Fights can be more aggressive however, often including alarm calls, visual contact, scent marking and a series of chases and retreats.[6] Adult males attack, inducing combative and loud vocalizations, while subadults chase one another.[3] Subsequently, there is a period of calm, and both groups forage for food and subadults examine the opposing group for mating opportunities.[3] The frequency of aggressive encounters increases during the breeding season and the majority of copulations occur during or directly after an aggressive encounter.[6]
Vocalizations allow moustached tamarins to distinguish between individuals, organize group movements, and ensure all members are accounted for. If individuals become separated, individuals of the same group will produce 2 to 3 second long vocalizations to indicate their location.[4] These calls consist of repeated short, frequency-modulated syllables ranging from 8 to 12 kilohertz.[4] In the morning, moustached tamarins make calls to each other to coordinate movement for the day towards specific foraging sites. Young tamarins also make vocalizations while they run and chase each other during play.
The reproduction season of the moustached tamarin monkey is November to March, during which the oldest female reproduces.[4] Females go into oestrus for about 17 days.[3] Their gestation period is about 145 days, after which females give birth.[4] Other members of the group help to take care of the infants, allowing the female to give birth more than once a year. The eldest female frequently bears twins because they ovulate multiple ova during each reproductive cycle.[3] The twins can be up to a quarter of the mother’s size at birth. Females reach reproductive maturity at about 480 days, and males at 540 days.[4] Both sexes migrate to a different group in adulthood to avoid the risk of inbreeding.[3] Moustached tamarins practice a variety of mating systems: polyandry, polygyny or polygynandry.[3] The mothers often receive help from up to 4 or 5 other members of the group. In polyandrous groups, the alpha male tolerates the presence of other males who can provide infant-care.[3] Not having enough helpers can sometimes lead to infanticide by the mother.[3]
The population trend for the moustached tamarin monkey is decreasing; however, the IUCN red list categorizes the moustache tamarin as least concerned.[7] They have demonstrated an ability to adapt to disturbed habitats and proximity to human settlements. They can acclimate well to changes in environmental conditions and their ecosystem. Habitat destruction remains an inevitable threat to their population as for all species living in the Amazonian rainforest. However, their ability to adapt gives hope that this factor will not severely affect their population numbers.
Moustached tamarin monkeys are economically significant because they are used extensively in biomedical research, like other tamarin species. They have been used in the development of the hepatitis A vaccine.
The moustached tamarin (Saguinus mystax) is a New World monkey and a species of tamarin. The moustached tamarin is named for the lack of coloring in the facial hair surrounding their mouth, appearing similar to a moustache. As with all New World monkeys, the moustached tamarin is found only in areas of Central and South America.
El tití bebeleche, tití de mustacho o tamarino bigotudo (Saguinus mystax)es una especie de primate platirrino de la familia Callitrichidae que habita en la Amazonia al occidente de Brasil, oriente del Perú y norte de Bolivia, hasta los 600 msnm.
Mide entre 23,5 y 28 cm de longitud, más la cola de 36 a 46 cm pesa entre 350 y 450 g. Su pelaje es negro, excepto en la boca, rodeada de blanco, que le da su nombre popular.
Vive en grupos de hasta 16 individuos con áreas de acción de hasta 50 hectáreas, que marca con señales olfativas. Es diurno y permanece en los árboles entre los 9 y 17 m de altura. Su dieta consta de frutas, resinas exudadas e insectos. Se defienden conjuntamente de los predadores y son capaces de hacer alejar a una boa. Frecuentemente están asociados con algún grupo de la especie Saguinus fuscicollis (tití de cabeza amarilla). Sólo una hembra del grupo se reproduce. El período de gestación es de 140 a 150 días.

Tamarin à moustaches
Le Tamarin à moustaches [1] (Saguinus mystax) est une espèce de primate de la famille des Cebidae.
Tamarin à moustaches de Lonnberg (S. m. pluto). Mustached tamarin. Pichico de barba blanca, pichico de bigote (Pérou).
Controversée. La forme pluto est considérée comme une sous-espèce de S. mystax (par Groves[2]) ou comme une espèce (par Mittermeier). La forme pileatus est considérée comme une espèce par Groves (nous le suivons ici), comme une sous-espèce de S. mystax par d’autres.
Est du Pérou, ouest du Brésil (États d’Amazonas et d’Acre) et peut-être extrême nord de la Bolivie.
Le nombre de sous-espèces est incertain (de 2 à 5 selon les auteurs) :
Deux populations isolées ont été observées par Izawa et Bejarano en 1981 au nord de la Bolivie (au sud du Rio Acre et au nord du Rio Tahuamanú) qui pourraient former un nouveau taxon apparenté à S. mystax ou à S. labiatus, voire être un hybride.
Enfin, certains considèrent encore que S. pileatus et S. pluto sont des sous-espèces de S. mystax.
Forêt pluviale primaire mature. Vieille forêt secondaire où ont repoussé de grands arbres. Forêt inondée. Forêt marécageuse. Jusqu’à 610 m d’altitude.
Le Tamarin à moustaches de Spix (S. m. mystax) est sympatrique du Tamarin à selle de Spix (S. f. fuscicollis). Le Tamarin à moustaches à croupe blanche (S. m. pluto) est sympatrique du Tamarin à selle d’Aviala-Pires (S. f. avilapiresi) sur toute sa distribution : ils évoluent en troupe mixte, le premier détectant les attaques aériennes et arboricoles, les seconds les attaques terrestres et des animaux grimpeurs.
Tamarin à moustaches de Spix (S. m. mystax) : presque tout son corps est brun noirâtre avec quelques poils gris ou chamois sombre sur le dos et les pattes arrière. Les seules zones blanches se situent au museau, autour des yeux (cercles fins), devant l’oreille et parfois autour des parties génitales.
Tamarin à croupe blanche (S. m. pluto) : identique au précédent mais le dessous de la base de la queue est blanc alors qu’il est noir chez S. m. mystax.
Les spécimens observés par Izawa et Bejarano ont le dos gris foncé, un ventre roux et une grande moustache.
Corps 26 cm (de 25 à 27 cm). Queue 39 cm (de 37 à 42 cm). Poids de 491 à 643 g (M) et de 508 à 640 g (F). Rapport longueur bras/jambes (x100) : 76. Caryotype : 2n = 46.
25 à 47,5 ha. Territorialité incertaine.
25/ km² (Río Manití, Pérou, d’après Soini et Cóppula). 26/km² (île de Padre, Pérou, d’après Garber).
Quadrupède. Évolue à 15-20 m au-dessus du sol en courant le long des branches et utilise rarement le mode de locomotion par sauts et accrochages plus typique du Tamarin à selle. Au repos, il peut enrouler sa queue devant lui.
Parcourt chaque jour 1,7 à 2 km. Se repose une grande partie de la journée et passe la nuit bien caché.
Frugivore-insectivore-exsudativore. Fruits, graines, exsudats, insectes, plus rarement œufs et petits vertébrés. Avale d’un coup les graines qui ressortent intactes dans ses excréments. Cette stratégie aurait pour effet de le rendre moins vulnérable aux rapaces et pour but de favoriser l’expulsion des parasites du système digestif. La consommation d’exsudats augmente entre septembre et décembre, lorsque les femelles sont enceintes. Capture les grenouilles arboricoles dans les strates moyenne et haute alors que le sympatrique Tamarin à selle capture les reptiles dans la basse strate et au sol. De même, le Tamarin à moustaches de Spix (S. m. mystax) consomme des tettigonies (grandes sauterelles) capturées dans la basse et moyenne strates alors que le sympatrique Tamarin à selle de Geoffroy (S. f. nigrifrons) consomme des tettigonies capturées entre 0 et 4 m, avec seulement trois espèces d’orthoptères communes aux deux singes. Comportement de géophagie observé au Pérou (Río Blanco).
5-6 (de 1 à 16), d’après Soini. 7 (de 4 à 11), sur l’île de Padre (Pérou, d’après Garber). 8 (de 6 à 11), dans les Sierras de Contamana, Pérou (d’après Aquino et al.). Rylands a observé des groupes avec 3 mâles adultes et jusqu’à 4 femelles adultes. Parfois, deux groupes s’assemblent temporairement.
Groupe multimâle-multifemelle. Principalement polyandrie, parfois polygynie ou monogamie. Sex-ratio : 1. On connaît ainsi des cas où deux femelles du même groupe ont mis bas, preuve que chez cette espèce (et chez le Tamarin à selle), la femelle inférieure n’est pas inhibée par l’odeur dégagée par la dominante. Mais la plupart du temps, une seule femelle se reproduit à la fois, avec une corrélation positive en fonction de l’âge.
La femelle met bas tous les 11 à 20 mois. Des faux jumeaux naissent après 140 à 150 jours de gestation, à longueur d’année mais avec un pic de naissances entre novembre et mars (d’après Snowdon et Soini) et entre juin et octobre (île de Padre). Développement : Il semblerait que, contrairement à ce qu’on observe chez les autres tamarins et ouistitis, la femelle transporte beaucoup les jeunes. Maturité sexuelle à 15-17 mois (F) et 17-18 mois (M).
Jusqu’à 20 ans.
Gazouillements, sifflements et trilles modulés par la langue vibrante.
Menace les intrus en érigeant sa crinière, en montrant les dents et poussant des cris perçants.
Laisse des sécrétions odorantes sur les arbres nourriciers, davantage pour renseigner les autres membres (communication intersexuelle) que pour avertir les étrangers qu’ils transgressent un domaine réservé (le marquage ne semblerait pas avoir de fonction territoriale). Urine dans ses mains puis répand le liquide sur les branches en se déplaçant. Frotte ses joues dans l’urine de son partenaire sexuel.
Allogrooming et autogrooming méticuleux. Dans deux petits groupes polygynes étudiés à Quebrada Branco, l’un des deux mâles adultes effectuait 70 % du grooming et toilettait équitablement tous les membres.
Petits félins. Rapaces (notamment faucon forestier Micrastur sp.). L’anaconda l’étouffe puis le gobe entier. On a observé un groupe parvenant à sauver un de leurs membres capturé par un boa constrictor.
Du fait de son poids (jusqu’à 700 g), l’homme le chasse pour sa chair. Cette espèce semble s’adapter assez mal aux transformations de l’habitat liées aux activités humaines.
Tamarin à moustaches de Spix (S. m. mystax) : Station écologique de Quebrada Branco (Pérou). PN de la Serra do Divisor et RE de Jutaí-Solimões (Brésil).
Tamarin à croupe blanche (S. m. pluto) : RB d’Abufarí, A. de protection d’Ayapuá, R. d’Uwasu et R. de Piagaçu-Purús (Brésil). Cette dernière sous-espèce est étudiée dans la région du lac Uauaçú.
Tamarin à moustaches
Le Tamarin à moustaches (Saguinus mystax) est une espèce de primate de la famille des Cebidae.
Il tamarino dai mustacchi (Saguinus mystax Spix, 1803) è un primate platirrino della famiglia dei Cebidi.
Con due sottospecie (Saguinus mystax mystax e Saguinus mystax pluto) vive in gran parte del bacino amazzonico brasiliano (stati di Amazonas, Acre e Rondônia), così come la Bolivia settentrionale ed il Perù orientale.
Preferisce le aree di confine fra foresta pluviale primaria e secondaria.
Misura circa 65 cm di lunghezza, di cui poco più della metà spetta alla coda, per un peso di 400 g.
Il pelo è nero scuro uniforme, fatta eccezione per un paio di baffoni bianchi (presenti in ambedue i sessi) che incorniciano il labbro superiore, e che danno il nome alla specie. La coda non è prensile, mentre le zampe presentano unghie appuntite simili ad artigli, fatta eccezione per i pollici (non opponibili) che sono dotati di un'unghia larga ed appiattita.
Si tratta di animali diurni ed arboricoli: vivono in gruppetti che contano generalmente meno di dieci individui. Caso raro tra i callitricidi, questi animali fanno ampio ricorso al grooming, in special modo i maschi. All'interno del gruppo possono a volte osservarsi episodi di tensione intraspecifica, generalmente scatenati dal mancato rispetto della gerarchia sociale durante i pasti.
Si tratta di animali onnivori: la loro dieta è incentrata su frutta ed insetti, anche se all'occasione possono catturare e mangiare piccoli vertebrati od uova. A differenza degli uistitì, mancano delle specializzazioni evolute per nutrirsi di linfa ed infatti non se ne nutrono mai: il fatto che questa fonte di cibo abbondante e poco dispendiosa da cercare sia assente dalla loro dieta si ripercuote anche sul numero dei gruppi, che nei tamarini è sempre inferiore rispetto agli uistitì.
La femmina partorisce due gemelli dopo una gestazione di cinque mesi: i cuccioli pesano complessivamente un quarto del peso materno e vengono trasportati dall'intero gruppo, per non affaticare ulteriormente la madre già provata dal parto, venendo lasciati a lei solo per la poppata, a intervalli di due o tre ore.
I cuccioli vengono svezzati attorno ai tre mesi e possono dirsi sessualmente maturi attorno ai due anni d'età.

Saguinus mystax[2][3] är en däggdjursart som först beskrevs av Johann Baptist von Spix 1823. Saguinus mystax ingår i släktet tamariner och familjen kloapor.[4][5] IUCN kategoriserar arten globalt som livskraftig.[1]
Inga underarter finns listade i Catalogue of Life.[4] Wilson & Reeder (2005) skiljer mellan två och IUCN mellan tre underarter.[1][6]
Arten når en kroppslängd (huvud och bål) av 24 till 27 cm, en svanslängd av 37 till 43 cm och en vikt av 500 till 600 g.[7] Pälsen har huvudsakligen en mörkbrun till svartaktig färg. Kännetecknande är ansiktets färgsättning. Regionen kring munnen och näsan är bara glest täckt med hår och där finns köttfärgad hud. Sedan följer en krans av vita hår som påminner om ett skägg. Saguinus mystax saknar den tredje molaren på varje sida av över- och underkäken. Liksom andra tamariner har den hörntänder som är längre än framtänderna. Svansen kan inte användas som gripverktyg. Med undantag av stortån, som har en nagel, är alla tår utrustade med klor. Tummarna är inte motsättliga.[8][9]
Denna kloapa förekommer i västra Amazonområdet i nordvästra Brasilien och angränsande delar av Peru. Habitatet utgörs av fuktiga skogar och andra skogar.[1]
Saguinus mystax har ungefär samma beteende som andra tamariner. Den äter frukter, nektar, blommor och naturgummi som kompletteras med några smådjur som insekter, grodor och ödlor. Individerna bildar flockar som har i genomsnitt 5 medlemmar. Flockarnas revir överlappar varandra. Det finns även blandade flockar med andra arter från samma släkte, till exempel Saguinus fuscicollis. Allmänt föder bara flockens dominanta hona ungar.[1]
Honor kan para sig hela året men de flesta ungar föds mellan november och mars. Hos några flockar dokumenterades två parningstider och deras ungar föds antingen mellan juni och oktober eller i februari/mars. Dräktigheten varar cirka 145 dagar och en kull har nästan alltid två ungar. Ungarna diar sin mor fem till sex månader (genomsnitt 171 dagar). Honor blir ungefär 16 månader efter födelsen könsmogna och hanar cirka två månader senare. Med människans vård kan arten leva 20 år.[8]
Individerna är aktiva på dagen och går på fyra fötter över grenar. Dessutom hoppar de ofta och de kan klättra uppför lodrätta stammar. Flocken medlemmar markerar träd som besöks ofta med körtelvätska. Dessutom har de olika läten för kommunikationen.[8][9]
I motsats till Saguinus fuscicollis letar arten oftare i trädens toppar cirka 10 meter över marken efter föda. Saguinus mystax jagas bland annat av rovdjur som kan klättra i träd, till exempel jaguarundi (Puma yaguarondi), tayra (Eira barbara) och ozelot (Leopardus pardalis). Ibland faller den offer för större ormar som kungsboa (Boa constrictor).[8]

Усатый тамарин (лат. Saguinus mystax) — вид игрунковых обезьян из рода тамаринов (Saguinus).
Различают два подвида:[1]
Усатые тамарины имеют темно-серую шерсть с характерными прядями белых волос над верхней губой, напоминающими усы. Половой диморфизм выражен слабо. Животные небольшого размера. Вес составляет в среднем 550 г для самцов и 500 г для самок.[2]
Обитают на большой территории в дождевых лесах восточного Перу и западной Бразилии (штаты Акри и Амазонас).[1]
Дневное животное, проводящее большую часть жизни на деревьях. Передвигается на четырёх конечностях, хорошо прыгает. Ищет пропитание чаще всего на высоте от 4 до 10 метров над уровнем земли, в рационе в основном фрукты, нектар, мелкие позвоночные и насекомые. Также питается древесными соками.[2] Усатые тамарины часто образуют смешанные группы с более мелким видом Saguinus fuscicollis, которому они симпатричны.
Образуют семейные группы от 4 до 15 особей, в среднем 2—8. Обычно в сезон размножения только одна самка из группы приносит потомство.
В 2008 году Международный союз охраны природы присвоил этому виду охранный статус «вызывает наименьшие опасения» (англ. Least concerned). В Перу и Бразилии плотность популяции от 30 до 70 особей на км2. Прямых угроз виду не выявлено, животные хорошо переносят небольшое вмешательство в среду обитания, в некоторых районах ареала даже являются объектом охоты.[1]
