Data and code for: Social phenotype-dependent selection of social environment in wild great and blue tits: An experimental study

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 phenoty...

越来越多的证据表明，个体在做出栖息地选择决策时，会主动评估自身表型（phenotype）与所处环境的匹配程度，即所谓的匹配型栖息地选择（matching habitat choice）。然而，据我们所知，目前尚无研究探讨社会环境与社会表型（social phenotype）如何在栖息地选择的决定过程中产生交互作用——尽管栖息地选择本质上是一项社会过程，且已有越来越多的证据表明个体在社交性（sociability）上存在差异。我们以野生大山雀（great tit）和蓝山雀（blue tit）为实验对象开展了一项实验，旨在探究鸟类在选择觅食地点与觅食方式时，如何整合自身社会表型与社会环境信息。我们通过可编程喂食器（programmable feeder）完成两项操作：(1) 记录鸟类的社会互动行为并估算其社会表型；(2) 对不同社会表型的鸟类所经历的局部种群密度进行实验性操控。通过追踪喂食器的使用情况，我们评估了社会环境与社会表型如何预测鸟类的喂食器选择与觅食行为。社会环境与社会表型均能
