每年，数十亿只鸟类在繁殖区和非繁殖区之间进行广泛的迁徙，面临着需要调整行为的挑战，特别是飞行时间和持续时间。这种日常活动模式的调整和外部因素（例如环境条件、月光）的影响在陆地移民中比在海洋移民中受到更多的研究关注。利用近几十年来广泛部署的组合式光位定位器-浸入式记录仪，我们研究了昼夜组织以及月球对来自广泛分类范围的 21 种迁徙海鸟（6 科，3 目）非繁殖季节飞行活动的影响。与一些不停飞行的陆生和湿地鸟类不同，海鸟在迁徙过程中会定期停下来（进食或休息）。我们发现，与居住在非繁殖地时相比，大多数海鸟物种在迁徙期间的飞行时间总体有所增加，对于某些物种来说，飞行时间也有所增加。此外，一些夜行性物种在迁徙期间飞行的时间比在非繁殖区的时间更长，对于昼行性物种反之亦然。在满月期间，无论是在迁徙期间还是在非繁殖地，夜间飞行的时间往往会增加，具体取决于物种。我们的研究对迁徙海鸟的活动模式进行了广泛的概述，为进一步研究潜在机制和驱动因素铺平了道路。
Every year, billions of birds undertake extensive migrations between breeding and non-breeding areas, facing challenges that require behavioural adjustments, particularly to flight timing and duration. Such adjustments in daily activity patterns and the influence of extrinsic factors (e.g., environmental conditions, moonlight) have received much more research attention in terrestrial than marine migrants. Taking advantage of the widespread deployment in recent decades of combined light-level geolocator-immersion loggers, we investigated diel organisation and influence of the moon on flight activities during the non-breeding season of 21 migrant seabird species from a wide taxonomic range (6 families, 3 orders). Migrant seabirds regularly stopped (to either feed or rest) during migration, unlike some terrestrial and wetland birds which fly non-stop. We found an overall increase for most seabird species in time in flight and, for several species, also in flight bout duration, during migration compared to when resident at the non-breeding grounds. Additionally, several nocturnal species spent more of the day in flight during migration than at non-breeding areas, and vice versa for diurnal species. Nocturnal time in flight tended to increase during full moon, both during migration and at the non-breeding grounds, depending on species. Our study provides an extensive overview of activity patterns of migrant seabirds, paving the way for further research on the underlying mechanisms and drivers.
