Behavioural Responses of Yunnan Snub-Nosed Monkeys (Rhinopithecus bieti) to Tourists in a Provisioned Monkey Group in Baimaxueshan Nature Reserve

Abstract

The appearance of tourists brings about behavioural changes in some primates. Primate behavioural responses to human activities can reflect their survival strategy. Little is known about how the behaviour of Rhinopithecus bieti changes in the presence of tourists. Here we provide the first detailed description of interactions between a provisioned group of R. bieti and tourists at Xiangguqing in Baimaxueshan Nature Reserve from July 2012 to June 2013. We found that R. bieti had different response rates to the 5 most common human actions (shout, photograph, offer food, clap, and wave). Results indicated that R. bieti expresses 10 behavioural reactions (threat, escape, vigilance, warning, panic, alliance, attack, foraging, approach, and staring) to tourists' actions. On the whole, most of the monkeys' responses were unfriendly or hostile; a small number were neutral and affiliative. Behavioural responses were also significantly different among the different age/sex classes. Immature individuals engaged in more affiliative behaviours than adult individuals, and adult males tended towards more hostile behaviours. The behaviour of R. bieti towards tourists showed both tension and adaptability. Scientific management of provisioned monkey groups and strict regulation of tourist behaviour is needed in order to protect the animals from the negative effects of tourism-related disturbance.

Impacts of the COVID‐19 pandemic on mammals at tourism destinations: a systematic review

“…If the lack of tourists continues for a long time, animals may move from one place to another in search of food and, as a consequence, they may no longer be sighted at particular tourism destinations, which will be detrimental to some tourism operators. Monkeys change their ranging patterns and their group sizes and increase their density in the context of provisioning for tourism (golden snub‐nosed monkeys Rhinopithecus roxellana , Xia et al 2016; Assamese macaques Macaca assamensis , Adhikari et al 2018; rhesus macaques Macaca mulatta , Sengupta & Radhakrishna 2018). Tourism often results in degradation of the surrounding habitat, and natural resources may be insufficient to support large numbers of monkeys, should provisioning lapse.…”

Invasion and defense of the basic social unit in a nonhuman primate society leads to sexual differences in the gut microbiome

“…Yunnan snub-nosed monkeys (R. bieti) form large, multilevel social groups consisting of many OMUs and an associated AMU (Xia et al 2020). The research group was a habituated wild group from May 2008 (Ren et al 2012b;Xia et al 2016). Since the end of 2009, all individuals were identified using distinctive physical characteristics such as body size, hair pattern, scars, and facial features (Xia et al 2020).…”

Determinants of Harem Size in a Polygynous Primate: Reproductive Success and Social Benefits

“…Yunnan snub-nosed monkeys form large, multilevel groups (bands) consisting of multiple harems and a loosely attached all-male unit (AMU) [53]. The research group is a habituated wild group, having been separated from the local natural group since May 2008 [56]. All individuals were identifiable based on distinctive physical characteristics such as body size, hair pattern, scars, facial features, and pelage color [29].…”
