动物二重唱最常被引用的功能性解释之一是加强了配对关系。然而，支持这一观点的证据充其量是有限的。本研究提供支持，通过记录对债券和二重唱在合趾猴之间的关系。作为一个工作假设，我们假设，如果duetting与成对键合，我们可能会期望看到duetting强度和成对键强度指标之间的关系。像大多数的狒狒物种一样，合趾猴能发出响亮、长而协调的二重唱。我们记录了每日的频率和持续时间的duetting和三个普遍接受的指标对债券的强度（相互梳理，行为同步和配偶之间的距离）在10个合趾组在动物园。理毛活动与理毛活动呈正相关。行为同步性与配偶间距离呈负相关。这些结果表明，生产协调的二重奏由合趾猴对是有关对键。(C)2000年，动物行为研究协会。
One of the most commonly cited functional explanations for animal duet songs is strengthening of the pair bond. However, the evidence to support this view is, at best, limited. This study provides support by documenting a relationship between pair bonds and duet singing in siamangs. As a working hypothesis, we assume that if duetting were related to pair bonding, we might expect to see a relationship between duetting intensity and indicators of pair bond strength. Like most gibbon species, siamang pairs produce loud, long and well-coordinated duet songs. We recorded daily frequency and duration of duetting and three generally accepted indicators of pair bond strength (mutual grooming, behavioural synchronization and distance between mates) in 10 siamang groups in zoos. Duetting activity was positively correlated with grooming activity and. behavioural synchronization, and negatively correlated with distance between mates. These results suggest that the production of coordinated duets by siamang pairs is related to pair bonding. (C) 2000 The Association for the Study of Animal Behaviour.
