Effective conservation of migratory species depends on understanding both migratory connectivity and migration strategy. The red‐necked stint Calidris ruficollis is a small, highly migratory sandpiper of the East Asian–Australasian Flyway, which is classified as 'Near Threatened' due to ongoing population declines. We tracked the migration of three red‐necked stints breeding in southern Chukotka, Russia, using geolocators, and supplemented our tracking data with re‐sighting records of color‐flagged individuals. The three birds, all of which bred within 2 km of each other, wintered in three different localities spanning nearly 5000 km. One individual completed its northward migration of >9400 km in two marathon flights; the second leg of that journey was completed in a nonstop flight of 5350 km. The successful conservation of just this one population requires protection of wintering sites across a vast area, coupled with key staging sites along the flyway. We suggest that other migratory species may pose similar conservation challenges.

追踪红颈猿Calidris ruficollis的迁徙揭示了马拉松飞行和意外的保护挑战

有效地保护迁徙物种取决于了解迁徙连通性和迁徙策略。脖子红的Calidris ruficollis是东亚-澳大拉西亚天桥的一个小型高度迁徙的,，由于人口持续下降，被归类为“濒临灭绝”。我们使用地理定位器跟踪了俄罗斯楚科奇南部南部三个红颈st繁殖的迁徙情况，并通过对色标个体的重新观察记录补充了我们的跟踪数据。这三只鸟在彼此之间相距2公里之内繁殖，并在跨越近5000公里的三个不同地方过冬。一名个人在两次马拉松飞行中完成了向北迁移超过9400公里的任务；旅程的第二站以5350公里的不间断飞行完成。要成功地保护这一种群，就需要保护广大地区的越冬地点，以及沿航道的重要登台地点。
