Data for: Foraging ecology and flocking behavior of insectivorous forest birds in Andean silvopastures

Foraging behavior of insectivorous forest birds in silvopastures and forest fragments of the Rio la Vieja watershed in the Colombian Andes. Foraging_GLM_FINAL includes attack rates, movement rates and prey size as responses to the predictors of habitat type and flock participation, using five species: Vireo olivaceus, Polioptila plumbea, Todirostrum cinereum, Hemithraupis guira and Pachysylvia semibrunnea. The other three csv files contain expected frequencies of use for different tree taxa based on importance values, versus observed frequencies of use for 11 'adaptable' species (including the previously mentioned five species; FR_gen and SP_gen), and 9 'sensitive' species (FR_sen).

本数据集聚焦哥伦比亚安第斯山脉里奥拉维哈流域林牧复合系统与森林片段内食虫林鸟的觅食行为。其中Foraging_GLM_FINAL以栖息地类型与集群参与度作为预测变量，选取红耳绿鹃（Vireo olivaceus）、灰蓝蚋鹩（Polioptila plumbea）、灰胸短尾霸鹟（Todirostrum cinereum）、桂红食籽雀（Hemithraupis guira）及褐顶绿鹃（Pachysylvia semibrunnea）共5个物种，涵盖取食攻击率、移动速率与猎物体型三类响应指标。其余三个CSV文件则基于重要值生成不同树木类群的预期利用频率，并对比了11种“适应性”鸟类（包含前述5个物种，对应FR_gen与SP_gen数据集）以及9种“敏感型”鸟类（对应FR_sen数据集）的实际树木利用频率。
