Life-history characteristics of European birds

Motivation: Birds are an extremely diverse group in terms of adaptations to environmental conditions, which is reflected in their life histories and ecological traits. Recently, functional aspects of avian diversity have been used frequently in comparative analyses as well as in community ecology studies; thus, open access to complete datasets of traits will be valuable. We focused on European bird species and compiled information about crucial ecological traits. This dataset is thus useful for research investigating large-scale patterns in European avifauna and can be used in various analyses in evolutionary ecology, macroecology or conservation biology. Main types of variables contained: We chose several types of avian traits, such as morphological (e.g., weight, wing, bill or tarsus length), reproductive (e.g., clutch size, egg mass, incubation period or type of young) and behavioural traits (type of nest, mating system or type of parental care), dietary (e.g., folivore, granivore...研究背景：鸟类在环境适应性方面呈现出极高的类群多样性，这一特征反映在其生活史与生态性状之中。近年来，鸟类多样性的功能维度被频繁应用于比较分析及群落生态学研究；因此，开放获取完整的性状数据集具有重要应用价值。本研究聚焦欧洲鸟类物种，整理了关键生态性状的相关信息。本数据集可用于探究欧洲鸟类区系的大尺度格局，也可应用于进化生态学、宏生态学或保护生物学等领域的各类分析。 包含的主要变量类型：我们选取了多类鸟类性状，包括形态学性状（如体重、翼长、喙长或跗跖长）、繁殖学性状（如窝卵数、卵重、孵化期或雏鸟类型）、行为学性状（巢型、婚配制度或双亲照料类型）以及食性性状（如食叶性、谷食性……
