野外川金丝猴声音行为的主要类型

川金丝猴(Rhinopithecus roxellana)栖息于高山森林中,营树栖生活,其声音通讯在社群活动中有重要意义。通过长期野外行为的观察和声音的录制,本文报道了川金丝猴在野外自然活动条件下声音行为的主要类型,明显可以辩别出惊异声、警戒声、警告声、呼唤声和安静状态下的叫声,并进行了声谱分析,发现其声谱的差异主要与声音目的有关,同时描述了每类声音发出相伴随的群的行为和身体运动的变化,讨论了笼养条件下和野外状况下川金丝猴声音行为的异同。

MAJOR CATEGORIES OF VOCAL BEHAVIOUR IN WILD SICHUAN GOLDEN MONKEY (RHINOPITHECUS ROXELLANA)

Sichuan golden monkeys are distributed in montane forests. Their vocal sounds have important functions in their situation of life. On the basis of observation of vocal behaviour and sound recording, this paper presents the major categories of vocalizations produced by free-living Sichuan golden monkeys, and describes their emission with accompanying troop behaviour and body movements. Differences between wild and captive animals are simply analysed here.
