Recently captured moustached tamarins (Saguinus mystax) were briefly separated from other members of their troop. Most separated animals emitted long calls that were, in general, similar in acoustic structure to those of sympatric tamarin species while retaining species distinctiveness. Individual differences also appeared in call structure. The long calls of a separated animal were responded to almost entirely by members of the animal's own troop rather than by other troops, and reciprocal calling occurred among troop members significantly more often than expected by chance. Although there was no evidence of troop-specific call structure or dialect, there were troop-specific responses to the calls of separated tamarins. This response implies the existence of a stable and integrated troop structure that allows troop members to learn and to respond to the individual specific features of each troop member's calls.
最近捕获的须长尾猴(Saguinus mystax)与猴群的其他成员短暂分离。大多数被分离的动物发出的长叫声在声学结构上与同域的其他长尾猴物种相似,但仍保留了物种的独特性。叫声结构也存在个体差异。一只被分离的动物的长叫声几乎完全被其自己猴群的成员所回应,而不是被其他猴群回应,猴群成员之间的相互回应比随机情况下的预期要频繁得多。尽管没有证据表明存在特定于猴群的叫声结构或方言,但对于被分离的长尾猴的叫声存在特定于猴群的回应。这种回应意味着存在一个稳定而整合的猴群结构,允许猴群成员学习和回应每个猴群成员叫声的个体特征。
