In: Dolhinow P, Fuentes A, editors. The first type is the polygynous group of variable numbers of females and one male. Patterns of mating among male patas monkeys (Erythrocebus patas) in Kenya. A patas must drink two or three times a day during the dry season (Gartlan 1974). Commensalism and conflict: the human-primate interface. 2013), Males are socially peripheral, rarely receiving affiliative behavior from females within the group (Nakagawa 1992), Single-male, multi-female groups most of the year (Hall 1966; Isbell 2013), Not a "harem" system, as in the hamadryas baboon (Mittermeier et al. 1984; Isbell 1998; Nakagawa 2008), Up to 7 males associated with a single group in one mating season, one study (Carlson and Isbell 2001), Females remain in natal group throughout life, typically (Isbell 2013), Larger groups may have multiple males (Chism and Rogers 1997), Resident male does not appear to have a reproductive advantage (Chism and Rogers 1997), All male groups, typically composed of dispersing males (Chism and Rogers 1997), Composition fluctuates; may not be stable groups, Fluctuates widely over time (Isbell 2013; Isbell et al. p 175-90. There are also instances in which patas were observed catching and eating fish out of evaporating natural pools in Senegal (Galat-Luong 1991). They are sold in the pet trade, and they sometimes play a role in medical research. Large home ranges also make defense quite difficult (the day range of this species is 4,330m +/-1,520m). 1983. [19][20], "Patas" redirects here. Males may have offspring with more than one female. 1984). These primates occupy the dry savannah landscapes of Tropical Africa. Another potential reason for such profound birth seasonality may be the availability of food during the breeding season which allows the prior years infant to be weaned, enabling the mothers to become pregnant again (Chism et al. In addition, they will occasionally assume a bipedal stance when alarmed, and can move bipedally if carrying an item in both hands (Hall 1965). Patas exhibit a low frequency of contact calling between individuals which may be as a result of the open nature of their habitat which facilitates visual contact instead (Nakagawa 1992). In: Kondo S, Kawai M, Ehara A, Kawamura S, editors. Encyclopedia Britannica, "britannica.com" (On-line). During the course of this association, the male and female patas monkey will copulate. incisors are spatulate, canines conspicuous, and molars are bilophodont. Ethology 103(2):109-26.

It was long debated if a defined dominance hierarchy of female patas monkeys existed but at present, the consensus is that it does exist. However, it is likely that patas monkeys fall victim to the standard predators of the subsaharan African savanna: lions, cheetah, African hunting dogs, jackels, brown hyenas, spotted hyenas, snakes, and raptors. All fields are required, VERIFICATION EMAIL Complete weaning of the infant only occurs when the mother gives birth to a new infant, typically around one year of age (Chism 1986). 1993), Allogroom, both genders and all ages groom other group members (Nakagawa 1992), Commonly observed, similar to that of baboons, Peak activity in morning, though observed throughout the day's resting period, Approaching, followed by close sitting is often an invitation for grooming, Receive < 10% of all grooming observations, Infants groomed by nearly all adult females, "Kiss"; observed in wild and individuals in managed care, One individual approaches another, stretching the head forward so that its mouth touches that of the other, Infants (aged 3 to 12 months) and juveniles, Frequently play for long periods, up to 30 minutes; no parallel in other terrestrial monkey, Bounce, chase, and wrestle; on the ground most often, Bounce alone or as an invitation to chase, Up and down, in the same spot; hopping quickly from hands to feet and back, continually; limbs held straight, Often with apparent high-speed enthusiasm, Alone; may run, full speed toward a bush, throwing the body sideways before making contact with the hands and feet; catapulting off and galloping away, Spar and wrestle; opponents stand on hind legs and face one another, Grapple with hands around shoulders and arms, Few observations of playing with or manipulating non-food objects, Adult females occasionally play with juveniles or their infants, Rare, only 49 episodes observed during the course of one 627 hours observational study, Aggression by one most often met by the rapid retreat of another, Little or no vocalization during aggression, Associated most commonly with 3 social situations, Rough play by a juvenile or young adult with an infant; mother directs threat-attack, Feeding areas with dense, clustered foods or those with a sought-after food resource (e.g. Patas Monkey audio clips provided by the Cornell Lab of Ornithology Macaulay Library. (Barbara B. Smuts, et al., 1987; Honolulu Zoo, 2005; Nowak, 1999). will be sent to address. Referring to something living or located adjacent to a waterbody (usually, but not always, a river or stream). They can tolerate arid conditions, and some of them have been found close to the southern edge of the Sahara desert. The appearance of patas monkeys contributes to the use of alternative names such as red guenons, Hussar monkeys, military monkeys, and dancing red monkeys. [5][7][8][9], The male common patas monkey grows to 60cm (24in) to 87cm (34in) in length, excluding the tail, which measures 75cm (30in).

However, it is difficult to know the exact gestation period because the females show no external signs of estrus. 1993). Ross C. 1991. Hall KRL. A consortship, as described above, lasts more than thirty minutes. Patas exhibit a large degree of sexual dimorphism with adult males weighing 12.4 kg (27.3 lb) and adult females weighing 6.5 kg (14.3 lb) on average (Galat-Luong et al. Rowell T. 1978. Listen to some of their vocalizations that I gathered. Terrestrial adaptations in the hands of cercopithecinae. Assessment of the diversity of African primates. Fire and grazing are important in the long-term maintenance of grasslands. "Patas Monkey" (On-line). Therefore, it is difficult to reliably estimate gestation periods in wild patas monkeys based on captive specimans. Convergent in birds. Volume one: behaviour. Reconciliation following aggression in patas monkeys, Erythrocebus patas. This behavior has been observed in both males and females. 1999. 1987. Patas monkeys avoid areas with dense cover, perhaps due to exposure to predators. Originally suggested to be a submissive/appeasement signal, this display has been argued not to convey such a message. Patas monkeys (Erythrocebus patas) live only in Africa. 1965; Struhsaker & Gartlan 1970). Most likely, females determine movements of the group and sleeping sites because they are more familiar with the home range of the group than the transitory males (Chism et al. Chism JB, Rowell TE. In Uganda, the patas home range was estimated to be 52 km (20.1 mi) and the daily path to be .7 km to 11.8 km (.43 to 7.33 mi) (Hall 1965). On at least one occasion in Cameroon, patas females of one group were observed to kidnap an infant from a different group, allomother it for a while and eventually abandon it (Nakagawa 1995). Although no specifically recorded for these monkeys, it is likely that some scent cues are used in reproduction. In a long term study, the mortality rate of infants and one year-old juveniles averaged 20% (Nakagawa et al. There is evidence of post-conflict reconciliation among patas females with increases in contact between former adversaries following agonistic interactions (York & Rowell 1988). Also search the current scientific literature for primate conservation status (overall as well as for individual species), and visitCITES(Convention on International Trade in Endangered Species of Wild Fauna and Flora). [10] Approximately three months postpartum, a darkening process begins returning the face to close to its pre-pregnancy color (Loy 1974). Patas monkeys are sometimes hunted for meat. 2013), Extra-group males converge on groups during the breeding season (Carlson and Isbell 2001; Chism et al. 1984). Also of importance to the patas is the inclusion of insects in their diet, as evidenced by the relatively high expenditure of foraging time to obtain them. (Honolulu Zoo, 2005; Nowak, 1999). Supplantation by a challenger male is sometimes followed by a short-lived multi-male polygynous mating system in which several males are actively breeding within a group (Ohsawa et al. Sexual weight dimorphism and social organization in green and patas monkeys in Senegal [abstract]. Erythrocebus patas: information (1) Chordata: specimens (6829) The Patas monkeys cheeks are able to contain as much food as their stomachs can. It may be the most Within this area of patas occupation is a great variety of climate and vegetation ranging from a dichotomy of hot, dry winters and rainy summers to areas where it can rain year-round. The most important trait of the Sahel is its precipitation which is low and seasonal (Gartlan 1974). Loy J, Harnois M. 1988. WebPatas monkeys, also known as hussar monkeys, wadi monkeys, nisnas, and singe rouge, are monkeys of the Cercopithecidae family. 1984). Males possess a bright blue scrotum (Groves 2001; Rowe 1996). The male interacts infrequently with the females of his group and spends most of his time at its periphery. Promiscuous events have been observed in which several males, from two to nineteen, joined a group during a breeding season. Hall KRL. WebChoose from Patas Monkey stock illustrations from iStock. Status or rank also seems to play a role in grooming of the adult male within a polygynous patas group. Unable to start download. Membership is free, secure and easy. Chism J, Rowell T, Olson D. 1984. When males leave the natal group at sexual maturity they may join an all male group or the male may live a solitary lifestyle. Grooming also serves to facilitate allomothering, as grooming of a mother may allow the groomer access to the mothers infant (Muroyama 1994). The body is about 50 to 70 cm, with the reddish-colored tail adding about the same amount to the total length. Rowe N. 1996. 1983). Etter HF. Folia Primatol 20: 331-50. Kingdon J. 12(5): 481-502. The genus status of the species has previously been in flux. 1978. In East African areas where patas ranges abut cropland, patas monkeys occasionally participate in crop raiding and use their high speed to escape when spotted by farmers (Lee & Priston 2005). Great for a zoo, or primate and monkey 1998a), Jump to the ground from heights of a few feet (, Young somersault from small bushes, landing on all fours, The ants and gum from the tree provide a large component of the patas diet, Patas eat gum and ants until the biting ant horde becomes too painful and the monkey moves on, Behavioral responses to predators dependent on nature of the threat, Vocalize to announce the nature of predatory threats, adults and immatures (see, When encountering signs of a predator on the ground, patas do not typically seek refuge in trees; an unusual response for a primate (Enstam and Isbell 2002; Isbell 2013; Isbell et al. 1974. Lab Prim News 17(1): 9-12. New York: Academic Pr. [13] During the breeding season, there are multi-male influxes into the group. Behaviour of patas monkeys, Erythrocebus patas, in captivity, with notes on the natural habitat. Their slender bodies and long limbs are morphologically suited for terrestrial movement and speed rather than for arboreal movement (Gartlan 1974). Superfamily: Cercopithecoidea The facial hair begins to lighten in the second trimester of pregnancy and is at its maximum lightness between 1.5 and 2.5 months postpartum (Loy 1974; Palmer et al. Folia Primatol 75(2): 70-84. Mating and residence patterns of male patas monkeys. The patas monkey prefers wide open areas and ventures only into those woodlands near open areas (Gartlan, pers. This may seem counter-intuitive since their home ranges are large. This may indicate weakening of matrilineal ties, rather than male aggression, as the main reason juveniles disperse from their natal group. They are found north of Africas equatorial forests and south of the Sahara Desert, with a distribution ranging from western Senegal to Kenya and northern Tanzania, although they are found at high Their especially long forelimbs facilitate this high running speed which provides an avenue of escape from predators (Etter 1973). WebAbstract The "Critically Endangered" southern patas monkey Erythrocebus baumstarki, thought to be endemic to Tanzania, has been resurrected to species level based on its geographic isolation, and on the coloration and pattern of its pelage. However, there are a few exceptions. Chicago: Univ Chicago Pr. Prim Conserv 20: 65-73. Phylogenetic evidence from 2003 appeared to validate him, finding the patas monkey to form a clade within the vervet genus Cercopithecus together with C. aethiops and C. lhoesti, and based on this study Erythrocebus was proposed to be sunk into synonymy with Cercopithecus. Reviewed by Karin Enstam. Kingdom: Animalia Phylum: Chordata Class: Mammalia Order: Primates comm. However, it has been observed that a network of dyads with characteristically more than average affiliative behavior exists which indicates that some sort of pattern of social behavior is present.
