群体中的动物可以从同步行为中受益，其中多个个体在同一时刻进行类似的活动。以前的研究表明，一些物种表现出同步的警惕行为，但没有探索驱动这种行为的机制。同步可能是由动物复制它们最近的邻居来驱动的，这意味着距离近应该会导致同步增加。我们同时观察了多个单独的黑头鸥（Chroicocephalus ridibundus）在休息组内的行为，并比较了一个焦点个体与其两个最近的邻居和一个随机选择的对照个体的活动。焦点个体更有可能与他们最近的邻居同步。如果个体不是最近的邻居，同步就不太可能了。这表明，群体内的同步性取决于其成员的空间位置，而黑头鸥更关注它们最近的邻居。
Animals in groups can benefit from synchronising their behaviour, where multiple individuals conduct similar activities at the same moment in time. Previous studies have demonstrated that some species show synchronisation of vigilance behaviour, but have not explored the mechanism driving this behaviour. Synchronisation could be driven by animals copying their closest neighbours, which would mean that close proximity should lead to increased synchronisation. We simultaneously observed the behaviour of multiple individual black-headed gulls (Chroicocephalus ridibundus) within resting groups, and compared the activity of a focal individual with its two closest neighbours and a randomly selected control individual. Focal individuals were more likely to be synchronised with their closest neighbour. Synchronisation became less likely if individuals were not the closest neighbour. This suggests that synchronisation seen within groups is dependent upon the spatial positions of its members, and black-headed gulls pay more attention to their closest neighbours.
