The male is larger than the female. The Japanese macaque is the northernmost-living monkey. [21] Nevertheless, a female will only groom a limited number of other females, even if the group expands. The dominant male has a role in siring young, deciding where the troop should go, and protecting the troop from predators and other macaque troops.

(1990) "Initiation and solicitation in male-female grooming in a wild Japanese macaque troop on Yakushima island". Hori T, Nakayama T, Tokura H, Hara F, Suzuki M. (1977) "Thermoregulation of the Japanese macaque living in a snowy mountain area". The macaque can cope with temperatures as low as −20 °C (−4 °F). Young macaques play with stones, fight and swing in trees. They inhabit evergreen and broad-leaved deciduous forest, from subtropical lowlands to sub-alpine regions of up to 1,500 meters high. Infants continue to be carried past a year. Yotsumoto N. (1976) "The daily activity rhythm in a troop of wild Japanese monkey". A macaque mother moves to the periphery of her troop to give birth in a secluded spot,[35] unless the group is moving, when the female must stay with it. [41] However, female infants have more social interaction than their male counterparts. In: Kondo S, Kawai M, Ehara A, editors. Takahashi H. (1997) "Huddling relationships in night-sleeping groups among wild Japanese macaques in Kinkazan island during winter". In addition, a Japanese macaque troop contains several matrilines. [59] The macaque also eats fungi, ferns, invertebrates, and other parts of plants. Food is hard to find, often hidden deep beneath the thick layers of ice and snow. In: Fa JE, Lindburg DG, editors. [52] Macaques in areas separated by only a few hundred miles can have very different pitches in their calls, their form of communication. It is found on three of the four main Japanese islands: Honshu, Shikoku, and Kyushu. They are also called the snow monkey because they often live in snowy regions. They range in size from just 14 in.

When there is snow around, they will make snowballs, rolling them about until they become too large or break up. [18], Females maintain both social relationships and hygiene through grooming. [19] Females which are matrilineally related groom each other more often than unrelated individuals. Blount B. (1983) "Physiological and social influences on mounting behaviour of troop-living female monkeys (. In colder areas, from autumn to early winter, macaques feed in between different activities. The Japanese macaque eats smaller animals and plants, mainly fruits, berries, seeds, flowers and young leaves, picking them from the surrounding vegetation. [12] Temporary all-male groups also exist, composed of those that have recently left their natal groups and are about to transfer to another group. [5] Infants are born with dark-brown hair. They also eat seeds, although seeds account for less than 20% of their food intake during these months. [11] Macaque groups tend to contain a number of adults of both sexes. Maruhashi T. (1981) "Activity patterns of a troop of Japanese monkeys (. [47], The Japanese macaque is an intelligent species. [38] However, alloparenting has been observed, usually by females which have not had infants of their own. [5] The southernmost population living on Yakushima Island is a subspecies of the mainland macaques, M. fuscata yakui. [23], A male and female macaque form a pair bond and mate, feed, rest, and travel together, and this typically lasts 16 days on average during the mating season. They are also great swimmers and have been reported to swim over half a kilometer. Sprague DS, Suzuki S, Tsukahara T. (1996) "Variation in social mechanisms by which males attained the alpha rank among Japanese macaques". Gouzoules H, Goy RW. Macaque groups tend to contain a number of adults of both sexes. Ventura R, Majolo B, Schino G, Hardie S. (2005) "Differential effects of ambient temperature and humidity on allogrooming, self-grooming, and scratching in wild Japanese macaques". Males have no copulatory vocalizations. [58] On Yakushima Island, fruit, mature leaves, and fallen seeds are primarily eaten. Most grow fur over the majority of their bodies, with the exception of their faces, which are hairless. [46] Macaques have alarm calls for alerting to danger, and other calls to signal estrus that sound similar to danger alerts. They can grow fungi that grow on the bark of trees. These matrilines may exist in a dominance hierarchy with all members of a specific group ranking over members of a lower-ranking group. [22] Mothers pass their grooming techniques to their offspring most probably through social rather than genetic means. [24] In addition, higher-ranking males try to disrupt consortships of lower-ranking males. (1976) "Life history of male Japanese monkeys". "Diachronic changes in the dominance relations of adult female Japanese monkeys of the Arashiyama B group". In: Fedigan LM & Asquith PJ, editors. Perloe SI. [11], The Japanese macaque (snow monkey) has featured prominently in the religion, folklore, and art of Japan, as well as in proverbs and idiomatic expressions in the Japanese language. Sprague DS. The Japanese macaque face no major threats at the species level. [36] Macaques usually give birth on the ground. These matrilines may exist in a dominance hierarchy with all members of a specific group ranking over members of a lower-ranking group. Koyama NF. [68][69] As the monkey is part of the Chinese zodiac, which has been used for centuries in Japan, the creature was sometimes portrayed in paintings of the Edo period as a tangible metaphor for a particular year. [63] A study in 1989 estimated the total population of wild Japanese macaques to be 114,431 monkeys. Except for humans, they are just other animals that wash them before eating their food! They wash their food before eating it. Not surprisingly, they're also known as snow monkeys. Japanese macaques consume a variety of insects and plants, and act as seed dispersers. Bardi M, Shimizu K, Fujita S, Borgognini-Tarli S, Huffman MA. [60] Further north, macaques mostly eat foods such as fruit and nuts to store fat for the winter, when food is scarce. It inhabits subtropical forests in the southern part of its range and subarctic forests in mountainous areas in the northern part of its range. Females stay in their birth group for life, but males leave the group before sexual maturity. (2003) "Matrilineal cohesion and social networks in. Gouzoules H. (1984) "Social relations of males and infants in a troop of Japanese monkeys: a consideration of causal mechanisms". Koyama N. I (1967) "On dominance rank and kinship of a wild Japanese monkey troop in Arashiyama". [5] The coat of the macaque is well-adapted to the cold and its thickness increases as temperatures decrease. Variants of the "girney" call are made in different contexts. [15] Females also exist in a stable dominance hierarchy, and a female's rank depends on her mother. The typical day for a macaque is 20.9% inactive, 22.8% traveling, 23.5% feeding, 27.9% social grooming, 1.2% self-grooming, and 3.7% other activities. Fedigan LM, Zohar S. (1997) "Sex differences in mortality of Japanese macaques: twenty-one years of data from the Arashiyama west population". They compete for some plants with Sika deer on Kinkazan Island, but when they climb trees to get the most energy sufficient leaves, in the process they knock down leaves, which the Sika deer eat.
