摘要
本文报道了野生猕猴通讯行为的初步研究结果。分别观察成年雌性和幼年猴的鸣叫和表情行为。猕猴正常时的表情自然轻松,有时发出一些声音。在听觉上成年雌猴的叫声为“hè”,幼年猴叫声为“ēn”,其最大共振峰频率Fmax分别为900Hz和1000Hz。猴受惊时表情紧张,双目圆睁,微张口,两嘴角外拉。成年雌猴和幼猴分别发出“kè”和“giè”的叫声,其最大共振峰频率分别为550Hz和350Hz,与正常叫声相比,惊叫声的最大共振峰频率降低,各单叫声持续的时间较短。
This paper report the preliminary investigation on communication behavior of rhesus monkey in field. The macaques were relaxed on normal state, and sometimes they made a kind of normal call. The call of adult female was 'he' with max vibrating peak frequency Fmax being 900 Hz, and the call of infant was 'en' with Fmax being 1000 Hz. The frightened call of adult female and infant was 'ke' and 'gie' with Fmax being 550 Hz and 350 Hz. The frightened female monkey opened her eyes wide and her facial expression was nervous. Comparing with normal call, the range of best frequency BF was smaller, Fmax was lower, and the time of one syllable was shoter in frightened call.
