The Foraging Guilds of Seabirds database

An ecological guild is a group of species that exploit the same resources, or that exploit the same or different resources in a related way. We build The Foraging Guilds of Seabirds database (FGSdb) by compiling a global database of 311 seabird species and assigning to each of them their diet types and foraging strategy. Across all seabirds, there were found 22 diets and 30 strategies. The number of diet categories for a species varied between 1 and 11, and the number of strategies varied from 1 to 9, with averages of 2.71 and 3.65, being the ratio diet/strategies of 0.74 (~3/4).生态类群（ecological guild）是指利用相同资源，或以相关方式利用相同或不同资源的物种类群。本研究构建了海鸟觅食类群数据库（The Foraging Guilds of Seabirds database，简称FGSdb），整合了包含311种海鸟的全球数据集，并为每个物种标注了其食性类型与觅食策略。在所有海鸟物种中，共识别出22种食性类别与30种觅食策略。单个物种的食性类别数量介于1至11之间，觅食策略数量则为1至9，对应平均值分别为2.71与3.65，食性与策略的比值为0.74（约3/4）。
