在许多复杂的社会中，复杂的沟通和识别系统可能会发展，以帮助支持群体成员的直接和间接利益。在合作繁殖的物种中，群体通常由亲属组成，学习和先天的声音信号都可以作为亲属识别的可靠线索。在这里，我们调查了声乐沟通的复数合作繁殖高超的椋鸟，Lamprotornis superbus，飞行呼叫短，刻板的发声接近同种时，可能会沟通亲属关系，群体成员，和/或个人身份。我们发现，飞行呼叫是最相似的个人剧目，但也更相似的群体内比更大的人口。虽然椋鸟对自己与其他邻近和遥远的社会群体的呼叫回放的反应不同，但呼叫相似性与遗传相关性无关。此外，移民女性表现出类似的模式，在研究人口出生的鸟类。总之，这些结果表明，飞行呼叫是反映社会联系的习得信号，但也可能携带个性信号。因此，航班呼叫为群体提供了可靠的识别机制，也可用于识别个人。在由相关和不相关的个体组成的复杂社会中，个体和群体联系的信号，而不是亲属关系，可能是合作的途径。
In many complex societies, intricate communication and recognition systems may evolve to help support both direct and indirect benefits of group membership. In cooperatively breeding species where groups typically comprise relatives, both learned and innate vocal signals may serve as reliable cues for kin recognition. Here, we investigated vocal communication in the plural cooperatively breeding superb starling, Lamprotornis superbus, where flight calls-short, stereotyped vocalizations used when approaching conspecifics-may communicate kin relationships, group membership, and/or individual identity. We found that flight calls were most similar within individual repertoires but were also more similar within groups than within the larger population. Although starlings responded differently to playback of calls from their own versus other neighboring and distant social groups, call similarity was uncorrelated with genetic relatedness. Additionally, immigrant females showed similar patterns to birds born in the study population. Together, these results suggest that flight calls are learned signals that reflect social association but may also carry a signal of individuality. Flight calls, therefore, provide a reliable recognition mechanism for groups and may also be used to recognize individuals. In complex societies comprising related and unrelated individuals, signaling individuality and group association, rather than kinship, may be a route to cooperation.
