摘要:

圈养动物行为研究对于改善动物福利、优化管理策略、指导濒危物种保护性繁殖以及揭示环境适应机制具有重要的科学价值。2022年10月至2023年12月, 作者在贵州森林野生动物园采用目标动物取样法与瞬时扫描记录法, 对圈养川金丝猴(Rhinopithecus roxellana)的行为内容、发生环境及其时间节律进行了系统观察与记录。基于“姿势-动作-环境” (posture-act-environment, PAE)三维框架, 结合行为的生态功能进行编码, 构建了适用于川金丝猴的PAE行为分类系统, 并据此建立系统的PAE行为谱。研究共记录到20种姿势、99种动作和69种行为, 并将行为划分为觅食、取食、亲密、调温、休息、运动、异常、繁殖、育幼、交配和其他共11个类别。不同年龄组的川金丝猴在日活动时间分配上表现出显著差异: 成年个体的休息行为频率高于青年个体, 而青年个体在运动、取食及游戏行为上的频率更高。在取食高峰期, 川金丝猴的休息频率下降, 运动频率上升; 在非取食高峰期, 其中午前运动频率逐渐降低, 随后缓慢回升至第2个取食高峰前达到峰值, 之后再度下降, 休息频率的变化趋势则与此相反。理毛行为与游戏行为的频率在中午时段达到高峰, 攻击行为及其他行为的整体频率变化较为平缓。本研究结果可为提升圈养川金丝猴的环境丰容水平、基础设施配置及食物供给策略等饲养管理措施提供理论依据。

Abstract

Aims: Research on the behavior of captive animals has significant scientific value for improving animal welfare, optimizing management strategies, guiding conservation breeding of endangered species, and revealing mechanisms of environmental adaptation. Golden snub-nosed monkeys (Rhinopithecus roxellana), a first-class nationally protected species in China, currently lack systematic behavioral studies across age groups based on individual identification. This research provides a theoretical basis for improving environmental enrichment, enclosure infrastructure, and food supply for captive golden snub-nosed monkeys.

Methods: From October 2022 to December 2023, we observed and recorded the behavior of captive golden snub-nosed monkeys at the Guizhou Forest and Wildlife Park. Based on the current population status of this species in captivity, we systematically documented behavioral expressions of target individuals, established an ethogram for captive golden snub-nosed monkeys, and used the PAE (posture-act-environment) coding system to classify and code the observed behaviors. Behavioral diagrams were constructed, and the time allocation patterns and behavioral rhythms of the monkeys were analyzed.

Results: The constructed PAE ethogram included 20 postures, 99 actions, and 69 distinct behaviors. These were classified into 11 categories: foraging, feeding, intimacy, thermoregulation, rest, movement, abnormal behaviors, reproduction, parenting, mating, and others. The daily activity distribution and rhythms of monkeys of different ages showed resting as the dominant activity, followed by movement, feeding, grooming, play, and aggression. Significant age-related differences were observed: adults rested more frequently, whereas juveniles engaged more often in movement, feeding, and play. During feeding peaks, resting decreased while movement increased. Outside feeding peaks, movement declined before noon, rose again until the second feeding peak, then declined. Grooming and play peaked around midday, while aggression and other behaviors remained relatively stable.

Conclusion: This study systematically documented the daytime behavior of captive golden snub-nosed monkeys, established a standardized classification system based on the PAE coding framework, and analyzed time allocation and behavioral rhythms. The findings indicate that the monkeys’ activity patterns align with the species’ typical energy-saving strategy while also reflecting adaptive adjustments to artificial feeding regimes. The PAE coding system developed here offers a quantifiable, repeatable method for behavioral research in captive primates, enhancing objectivity and comparability in ethological studies. These results provide a scientific basis for optimizing management practices for captive golden snub-nosed monkeys and lay the groundwork for welfare assessment and future behavioral ecology studies of wild populations.
