Passeriformes (passerine)

The mean clutch size and additional information on hatchling success, fledging success, incubation duration, and habitat type are compiled for the 30 species within the taxonomic group Passeriformes (passerine), also known as perching birds. The data is taken from global locations and has been compiled to review differences within clutch size due to environmental differences such as climate. It is already mentioned that tropical birds reproduce a smaller clutch due to higher annual survival than birds in temperate regions (Muñoz et al., 2018 & Young, 1996). Therefore, with climates changing globally, it is interesting to review whether clutch sizes in temperate and tropical regions change over time. With biodiversity changing across the globe, will the passerine species have to adapt to the new environment by changing their clutch sizes? To find the dataset I used the search engines google scholar, science direct, Web of Science and Scopus. I searched for the key words, clutch size and the species name. I made a list of species from the passerine group by using google.本数据集汇编了雀形目（Passeriformes，又称栖木鸟类）下30个物种的平均窝卵数（clutch size），以及雏鸟出壳存活率、离巢存活率、孵化时长与栖息地类型等补充信息。数据采集自全球各地，旨在探究气候等环境差异导致的窝卵数差异。已有研究表明，相较于温带地区鸟类，热带鸟类因年存活率更高，窝卵数更小（Muñoz等人，2018；Young，1996）。因此，在全球气候变化的背景下，探究温带与热带地区鸟类窝卵数是否随时间发生变化具有重要研究价值。随着全球生物多样性持续改变，雀形目物种是否会通过调整窝卵数以适应全新环境？ 本数据集的检索数据源涵盖谷歌学术（Google Scholar）、ScienceDirect、Web of Science与Scopus四大学术搜索引擎。检索时以“窝卵数”与对应物种名称作为关键词。通过谷歌搜索整理出雀形目类群的物种名录。
