Abstract

Making a decision as a group requires not only choosing where to go but also when to go. A new study provides experimental evidence that, in jackdaws, vocalisations facilitate synchronous early morning departures from communal roosts.

摘要

作为一个群体做出决策不仅需要选择去哪里，还需要选择何时出发。一项新的研究提供了实验证据，表明在寒鸦中，叫声有助于它们在清晨同步离开公共栖息地。
