Vocal communication plays an important role in the regulation of social interactions and the coordination of activities in many animal species. Synchrony is an essential part of the establishment and maintenance of pair bonds, but few reports have investigated decision-making at the pair level. We investigated temporal characteristics of call exchanges in pale-winged starlings (Onychognathus nabouroup) that could predict whether one, two, or neither members of a pair would take off. Our analysis of these interactions revealed that the overall rhythm of a call exchange, as well as the acceleration towards the end of an interaction, were significantly associated with the type of behavioural outcome. Faster rhythms were associated with higher probabilities that both birds would fly away. Our results confirm the findings of previous studies showing that higher rates of alarm calls indicate imminent departure and highlight the relationship between temporal features of vocal interactions and their outcome.

称呼节奏为预测声音交互作用的结果：苍白star鸟成对飞翔

声乐交流在许多动物物种的社交互动和活动协调中起着重要作用。同步是建立和维持配对债券的重要组成部分，但是很少有报告调查配对配对的决策。我们调查了苍白star鸟（Onychognathus nabouroup）可以预测一对中的一个，两个或两个都不起飞。我们对这些交互的分析表明，呼叫交换的整体节奏以及交互结束时的加速与行为结果的类型密切相关。节律越快，两只鸟都会飞走的可能性就越高。我们的结果证实了先前研究的结果，该研究表明较高的警报声提示即将离去，并突出了声音交互作用的时间特征与其结果之间的关系。
