A plethora of studies have offered crucial insights in the phylogeographic status of Western Palearctic bird species. However, an overview integrating all this information and analyzing the combined results is still missing. In this study, we compiled all published peer-reviewed and grey literature available on the phylogeography of Western Palearctic bird species. Our literature review indicates a total number of 198 studies, with the overwhelming majority published as journal articles ( = 186). In total, these literature items offer information on 145 bird species. 85 of these species are characterized by low genetic differentiation, 46 species indicate genetic variation but no geographic structuring i.e. panmixia, while 14 species show geographically distinct lineages and haplotypes. Majority of bird species inhabiting the Western Palearctic display genetic admixture. The glaciation cycles in the past few million years were pivotal factors in shaping this situation: during warm periods many species expanded their distribution range to the north over wide areas of Eurasia; whereas, during ice ages most areas were no longer suitable and species retreated to refugia, where lineages mixed.

大量研究为西古北区鸟类物种的系统地理学状况提供了关键见解。然而，整合所有这些信息并分析综合结果的综述仍然缺失。在本研究中，我们汇编了所有已发表的关于西古北区鸟类物种系统地理学的同行评审文献和灰色文献。我们的文献综述显示共有198项研究，其中绝大多数以期刊文章形式发表（= 186篇）。这些文献总共提供了145种鸟类的信息。其中85种物种的遗传分化程度较低，46种物种显示出遗传变异但没有地理结构，即随机交配，而14种物种表现出地理上不同的谱系和单倍型。栖息在西古北区的大多数鸟类物种表现出遗传混合。过去几百万年的冰川周期是形成这种情况的关键因素：在温暖时期，许多物种将其分布范围向北扩展到欧亚大陆的广大地区；而在冰河时代，大多数地区不再适宜生存，物种退缩到避难所，在那里谱系混合。
