Knowledge of the origin and spatial distribution of migratory bird contingents is essential information for the study and conservation of their populations. In short-distance migratory birds, their propensity to migrate has reduced over the past decades: more individuals remain year-round on the breeding grounds, and those that migrate winter at closer distance. To inform the management of these migratory populations and species subject to intensive hunting during the non-breeding season, we must document and understand how their migratory behaviours have changed over the past decades. Using ringing-recovery data spanning over the past 70 years (1950–2018), we updated knowledge on origins and within-France spatial distribution of five hunted European turdids migrating to/through France (common blackbird, fieldfare, song thrush, redwing and mistle thrush), and documented how these aspects have changed over time. Our results confirm that France hosts non-breeding birds from all Continental Europe. Partial and short-distance migratory populations from blackbird mainly come from western and central Europe and are strongly segregated in autumn and winter in France according to their origin. Surprisingly, our results relativize the presence of populations originating from Fennoscandia for the northernmost species (redwing and fieldfare), which present a slightly marked segregation. Finally, this study highlighted temporal changes in the migratory propensity for song thrush and mistle thrush, and modifications of the within-France spatial distribution for fieldfare, song thrush, and redwing. Through this new knowledge, we hope to provide a replicable method to characterize migratory populations’ distribution and bring elements to promote the differentiated management of hunted thrushes in Europe

了解候鸟种群的起源和空间分布是研究和保护候鸟种群的重要信息。在短距离候鸟中，它们的迁徙倾向在过去几十年中有所降低：更多的个体常年留在繁殖地，而那些在更近的距离越冬的候鸟。为了告知这些在非繁殖季节受到密集狩猎的迁徙种群和物种的管理，我们必须记录并了解它们的迁徙行为在过去几十年中是如何变化的。使用过去 70 年（1950-2018 年）的振铃恢复数据，我们更新了迁徙到/途经法国的五只被猎杀的欧洲鸬鹚的起源和法国境内空间分布的知识（普通黑鹂、田野鸫、鹅口疮、红翼和槲寄生），并记录了这些方面是如何随着时间的推移而变化的。我们的结果证实，法国拥有来自整个欧洲大陆的非繁殖鸟类。黑鹂的部分和短距离迁徙种群主要来自西欧和中欧，并在法国秋季和冬季根据其来源进行了强烈的隔离。令人惊讶的是，我们的结果相对于最北端的物种（红翅和野鸭）起源于 Fennoscandia 的种群的存在，它们呈现出略微明显的隔离。最后，这项研究强调了鹅口疮和槲寄生的迁徙倾向的时间变化，以及法国境内田野、鹅口疮和红翅的空间分布的变化。通过这些新知识，
