越来越多的证据表明，个体在做出栖息地选择决策时，会主动评估其表型与环境之间的匹配（所谓的匹配栖息地选择）。然而，据我们所知，尽管栖息地选择是一个内在的社会过程，而且越来越多的证据表明，个体的社交性存在差异，但还没有研究考虑到社会环境如何与社会表型相互作用来决定栖息地选择。我们利用野生大山雀和蓝山雀进行了一项实验，以了解鸟类在选择觅食地点和方式时如何整合其社会表型和社会环境。我们使用可编程喂食器来(i)记录社会互动并估计社会表型，以及（ii）通过实验操纵不同社会表型的鸟类所经历的局部密度。通过跟踪喂食器的使用情况，我们估计了社会环境和社会表型如何预测喂食器的选择和摄食行为。社会环境和社会表型都预测了喂食器的使用，但鸟类留在特定社会环境中的决定并不取决于它们的社会表型。相比之下，对于进食行为，对社会环境的反应取决于社会表型。我们的研究结果提供了罕见的匹配栖息地选择的证据，并揭示了栖息地选择对社会表型个体间差异的依赖性。
There is growing evidence that individuals actively assess the match between their phenotype and their environment when making habitat choice decisions (so-called matching habitat choice). However, to our knowledge, no studies have considered how the social environment may interact with social phenotype in determining habitat choice, despite habitat choice being an inherently social process and growing evidence for individual variation in sociability. We conducted an experiment using wild great and blue tits to understand how birds integrate their social phenotype and social environment when choosing where and how to feed. We used programmable feeders to (i) record social interactions and estimate social phenotype, and (ii) experimentally manipulate the local density experienced by birds of differing social phenotype. By tracking feeder usage, we estimated how social environment and social phenotype predicted feeder choice and feeding behaviour. Both social environment and social phenotype predicted feeder usage, but a bird's decision to remain in a particular social environment did not depend on their social phenotype. By contrast, for feeding behaviour, responses to the social environment depended on social phenotype. Our results provide rare evidence of matching habitat choice and shed light on the dependence of habitat choice on between-individual differences in social phenotype.
