Overview

Brief Summary

Biology

This monkey lives either in monogamous pairs or in multi-male / multi-female groups of up to 10 (2). Mating occurs during the wet season from September to November in the wild. Females are polyoestrous and have a gestation period of between 145-152 days (3) (2). Single young are usually produced and females have been known to give birth two times a year (5). The mother cares for the infant for the first 10-20 days of its life though after this other members of the group assist in caring for it (3). After seven weeks the juvenile is able to move and forage by itself and sexual maturity is reached at 18-24 months (3). The diet includes fruits, insects, fungi and some vertebrates (2). It usually forages in the understory of the forest, though it will occasionally travel to the forest floor or higher in the trees to feed (3). Goeldi's monkey moves with agility through the forest on all fours and is able to leap distances of up to four metres between branches, which is quite spectacular for such a small monkey (3) (5).

Comprehensive Description

Description

Goeldi's monkey is a small, rare inhabitant of the Amazon (5). Adults are blackish brown with thick, soft hair and a mane draping from the neck and the shoulders (3). When threatened, Goeldi's monkey takes an arched posture and raises its bristles in defence to look larger (5). The head and dorsal surface may be spotted with white flecks, and the tail may have two or three light coloured rings at the base. Juveniles are similar in appearance, though they lack these tail rings and the draping mane around the neck and shoulders (5).

Distribution

Range Description

Callimico goeldii occurs in the upper Amazon from the Rio Caquetá in Colombia, south through the Peruvian Amazon and the extreme western Amazon of Brazil into the Pando region of northern Bolivia (Hernández-Camacho and Barriga-Bonilla 1966; Hernández-Camacho and Cooper 1976; Hershkovitz 1977). Hershkovitz (1977) predicted that it should occur in the Ecuadorian Amazon, but it has not been found there to date. Despite its wide range, Callimico is notoriously patchy in its distribution and is evidently absent over a large part of it. In Colombia, it occurs from the base of the Cordillera Oriental of the Andes in the Department of Putumayo between the Ríos Putumayo and Caquetá east at least to the mouth of the Río Cahuinarí, a right bank affluent of the Caquetá. It is not known to occur in the Colombian trapezius (Hernández-Camacho and Cooper 1976; Defler 2003, 2004). In Peru, it is evidently limited largely to the eastern Amazon. Hershkovitz (1977) mapped numerous localities south of the Río Napo, along the lower and middle Río Ucayali and the Río Tapiche. The westernmost locality given by Hershkovitz (1977, map p.864) is on the Rio Marañon, but it is listed in the gazetteer as “Apaga (Rio), enters Río Putumayo from south at approximately 4º42'S, 77º10'W, P. Soini, April 1970, sight record”. The coordinates would seem to be right, but the description of the locality wrong, and the Rio Marañon is excluded from the distribution map of Aquino and Encarnación (1994a). These authors have Callimico only definitely occurring south of the lower Ucayali (from the mouth of the Rio Blanco), extending to both sides of the Ucayali at about 6ºS and south along the Andean foothills to the Río Pachitea and the Madre de Dios. It occurs in the Manu National Park (Aquino and Encarnación 1994a). From there it extends east into extreme northern Bolivia, north of the Río Tahuamanu (Buchanan-Smith et al. 2000; Christen and Geismann 1994). Christen and Geismann (1994) reported seeing Callimico south of the Río Nareuda, indicating it occurs south as far as the Rio Muyumanu. Buchanan-Smith et al. (2000) found no evidence of its occurrence south of the Tahuamanu-Nareuda. Callimico occurs in a small part of the south-west Brazilian Amazon in the state of Acre, through the Serra do Divisor south of the upper Rio Juruá to the Rio Gregório (state of Amazonas), to the Rio Iaco (above the Rio Acre) on the south (right) bank of the upper Purus, and into the Madeira basin along the Rio Abunã in the state of Rondônia (Hershkovitz 1977; Ferrari et al. 1999; Lopes and Rehg 2003).

Morphology

Physical Description

According to a study by Hershkovitz (1977), Callimico goeldii are small with a length of 210-234 mm, and a tail length of 255-324 mm. They are dark brown or black with possible white areas on and around the face. Longer hairs form "a mane [that] drapes from the neck and shoulders and extend also from above the base of the tail" (Nowak 1999). Adults have pale rings on the tail. Other characteristics include clawlike nails on all of the digits excluding the large toe and a dental formula of 2/2, 1/1, 3/3, 3/3.

Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
Occurs in forest mixed with bamboo, and in varillales (large stands of thin, straight trees). Izawa (1979), Buchanan-Smith (1991a), and Ferrari et al. (1999) have indicated that it is a habitat specialist concentrating on bamboo forests and disturbed forests (secondary growth) related to their tendency to spend much of their time in the lowest parts the forest understorey in dense vegetation. They can also be found in more open, mature forest (Christen and Geissmann 1994; Christen 1998, 1999). Porter (2007) quantified the time a group spent in different habitat types during the course of a year: primary forest with dense understorey 76%; bamboo forest 10%; secondary forest 3%. The group used bamboo forest more than the sympatric tamarins (S. fuscicollis and S. labiatus). Its preference for dense vegetation is related to its extraordinary inclusion of fungi in its diet and to its insect foraging behaviour. Bamboo, stream edge, and tree falls are where they are able to find the jelly fungi and bamboo fungi that they appreciate (Pook and Pook 1981; Porter and Christen 2002; Porte, 2007; Porter et al, 2007).

The diet of Callimico includes fruit, arthropods (especially orthopterans and stick insects), fungi, and exudates. Porter (2007; Porter and Christen 2002; see also Hanson et al. 2006) found that fungi were an essential and considerable component of the diet. Two types were eaten: jelly fungi (Auricularia, 3 species) and bamboo fungi (Ascopolyporous, 2 species). In some months (May-July, dry season) fungi accounted for 48-63% of the feeding records. Callimico forages for arthropods in the understorey and beneath the leaf litter on the forest floor. They are understorey specialists spending 84% of their time foraging below 5 m above the ground (saddleback tamarins tend to forage more a little higher, up to 10 m above the ground, and the moustached tamarins forage even higher up, mostly in the middle and lower canopy - above 10 m (Yoneda 1981; Buchanan-Smith 1999; Porter 2007). Callimico tends to eat more vertebrates (frogs and lizards) than the tamarins. For a review see Heltne et al. (1981).

In her long-term study of Callimico, Porter found that one group used an area of 114 ha, covering the entire home ranges of six tamarin groups (Porter 2007; Porter et al. 2007). Rehg (2003, 2007) on the other found her Callimico group using a range of about 59 ha; similar in size to the Saguinus labiatus group which they travelled with for about 67% of the time. Group size 7 (six adults and subadults and an infant). Callimico groups can be as large as 12 (Encarnación and Heymann 1998) and unlike other callitrichids can have more than one breeding female (Masataka 1981a, 1981b). Copulations occur as soon as 10 days after the female gives birth indicating post-partum oestrus. They produce single offspring. Other members of the group help carry the young (communal breeding), with the first transfer from the mother a few days (4-11) after birth.

Callimico travels and forages with saddleback tamarins (Saguinus fuscicollis) and moustached tamarins (Saguinus mystax, Saguinus labiatus, and Saguinus imperator) (Pook and Pook 1979a,b, 1981, 1982a). Lopes and Rehg (2003) recorded Callimico associating with S. imperator in the Serra do Divisor National Park, Brazil. Rehg (2003, 2006) and Porter (2001, 2007) studied the associations between Callimico, Saguinus labiatus, and S. fuscicollis weddelli in south-eastern Acre, Brazil, and north-western Pando, Bolivia, respectively. Porter (2007) reviews in detail the different specializations of Callimico, saddleback tamarins and moustached tamarins that allow for their sympatry.

Habitat

Pook (1990) reports that Callimico goeldii inhabit areas of the Amazon rainforest that have patchy canopy cover and strong undergrowth. Thornback and Jenkins (1982) describe it as "shabby forest such as mixed forest, scrub, second-growth woods, bamboo forests, and forest with discontinuous canopies and well-developed scrub. The majority of their time is spent at levels of less than 5 meters with forays to higher elevations for fruit.

Trophic Strategy

Food Habits

The diet of Callimico goeldii consists primarily of fruits, insects, and small vertebrates. A group of Goeldi's monkeys will travel and feed in fruiting trees. Competition for fruit seems not to be a problem. They hunt individually, leaping to the ground to obtain small verebrates.

Conservation Status

Callimico goeldii are listed as Appendix I under CITES, therefore commercial import and export has been banned. This is not well enforced in Bolivia. Loss of habitat and dangers from hunting and trapping are severely threatening Callimico goeldii populations. They seem to do well under captive conditions, and are housed in a number of zoos worldwide with highly successful breeding programs at the Jersey Wildlife Preservation Trust (GB) and the Brookfield Zoo (Chicago).

Population

Population
Very localized and patchy distribution. Always rare and difficult to observe. Groups are generally widely separated, determined by the availability of the right mix/mosaic of habitats and food availability. Key habitat such as stream edge, bamboo forest and secondary growth patches are needed due to their predilection for certain species of fungus.

Recorded population density estimates in Bolivia, include: 0.29 groups/km² (Izawa and Yoneda 1981); 0.25 groups/km² (Pook and Pook 1981); 9.6 individuals/km² (Cameron et al. 1989); and 6.1 individuals/km² (Porter 2007).

Rehg (2003, 2007) recorded 0.8-1.2 groups/km² in an 820-ha forest patch in Acre, Brazil. This is higher than density estimates recorded from Bolivia, and Rehg (2007) believed it might be related to habitat heterogeneity, including disturbance associated with tree falls.

Porter (2007) combined all group counts reported in the literature and calculated an average group size of 6.4 individuals, and a general population density of 5.6 individuals/km² where they occur. At one site in the far north-west of Bolivia, Porter (2007) estimated 37 individuals/km².

Major Threats
Although there are probably no major threats at present, the species is at risk of becoming threatened very quickly depending on proposed development projects, and logging in areas where it is known to occur.

Bamboo often reforests areas that have been cleared for agriculture or pasture. Studies are needed to determine Callimico's degree of tolerance for habitat disturbance in its range (Porter 2007).

Conservation

The Convention on International Trade in Endangered Species (CITES) has listed this species on Appendix I, prohibiting its international trade. However, since Goeldi's monkey is rare, its value on the international black market is increasing (4). Sadly, there is little protection of this species in its natural habitat across its range. In Colombia it has been seen in only six sites, of which only two are in National Parks (6). Should the other four sites prove to be attractive for human development or colonisation, this species is likely to become threatened. A first step for the conservation of Goeldi's monkey is therefore to ascertain this species' precise range, population locations and numbers (6). Since this species is naturally rare and dependant on a specialised habitat it will be important to take proactive steps to protect it as parts of its range may soon come under development (3).

Wikipedia

Goeldi's marmoset

Goeldi's marmoset or Goeldi's monkey (Callimico goeldii) is a small, South American New World monkey that lives in the upper Amazon Basin region of Bolivia, Brazil, Colombia, Ecuador, and Peru. It is the only species classified in the genus Callimico, and the monkeys are sometimes referred to as "callimicos".

Goeldi's marmosets are blackish or blackish-brown in color and the hair on their head and tail sometimes has red, white, or silverly brown highlights.[4] Their bodies are about 8–9 inches (20–23 cm) long, and their tails are about 10–12 inches (25–30 cm) long.

Goeldi's marmoset was first described in 1904, making Callimico one of the more recent monkey genera to be described. In older classification schemes it was sometimes placed in its own family Callimiconidae and sometimes along with the marmosets and tamarins in the subfamily Callitrichinae in the family Cebidae. More recently, Callitrichinae has been (re-)elevated to family status as Callitrichidae.

A Marmoset eating a butterfly.

Females reach sexual maturity at 8.5 months, males at 16.5 months. The gestation period lasts from 140 to 180 days. Unlike other New World monkeys, they have the capacity to give birth twice a year. The mother carries a single baby monkey per pregnancy, whereas most other species in the family Callitrichidae usually give birth to twins. For the first 2-3 weeks the mother acts as the primary caregiver until the father takes over most of the responsibilities except for nursing. The infant is weaned after about 65 days. Females outnumber males by 2 to 1.[4] The life expectancy in captivity is about 10 years.

Goeldi's marmosets prefer to forage in dense scrubby undergrowth; perhaps because of this, they are rare, with groups living in separate patches of suitable habitat, separated by miles of unsuitable flora. In the wet season, their diet includes fruit, insects, spiders, lizards, frogs, and snakes. In the dry season, they feed on fungi, the only tropical primates known to depend on this source of food. They live in small social groups (approximately six individuals) that stay within a few feet of one another most of the time, staying in contact via high-pitched calls. They are also known to form polyspecific groups with tamarins, perhaps because Goeldi's Marmosets are not known to have the X-linked polymorphism which enables some individuals of other New World Monkey species to see in full tri-chromatic vision.[5]

The species takes its name from its discoverer, the Swiss naturalist Emil August Goeldi.
