栖息地选择和扩散行为是进化生态学中的关键过程。最近的研究表明，个体可以利用同种生物的繁殖性能作为关于繁殖斑块质量的公共信息来源，以做出扩散决策，但关于物种聚集繁殖的实验证据仍然有限，即集群物种。我们通过操纵被标记个体及其邻居在一系列殖民地海鸟--黑腿猫尾鸟(Rissa Tridactyla)--的一系列繁殖区上的繁殖成功来解决这个问题。根据之前对这一物种的观察，我们预测，在成功的斑块上丢失卵子的个体将回到自己的巢中，并在第二年以更高的速度回到巢中，而在邻居也失败的斑块上丢失卵子的个体的比率更高。正如预测的那样，繁育者和探矿者的出席受到当地繁殖成功程度的强烈影响，导致不同的地点保真度和招聘。这表明个体利用同种繁育表现传递的信息来做出与繁育地点选择有关的决定。这一过程可以放大这些种群对环境变化的反应，并可能有助于殖民地繁殖的进化。
Habitat selection and dispersal behaviour are key processes in evolutionary ecology. Recent studies have suggested that individuals may use the reproductive performance of conspecifics as a source of public information on breeding patch quality for dispersal decisions, but experimental evidence is still limited for species breeding in aggregates, i.e. colonial species. We addressed this issue by manipulating the local breeding success of marked individuals and that of their neighbours on a series of breeding patches of a colonial seabird, the black-legged kittiwake (Rissa tridactyla). Based on previous observations in this species, we predicted that individuals that lost their eggs on successful patches would attend their nest and come back to it the year after at a higher rate than individuals that lost their eggs on patches where their neighbours were also in failure. As predicted, the attendance of breeders and prospectors was strongly affected by the local level of breeding success, resulting in differential site fidelity and recruitment. This suggests that individuals used information conveyed by conspecific breeding performance to make decisions relative to breeding site selection. This process can amplify the response of these populations to environmental change and may have contributed to the evolution of colonial breeding.
