What determines why some birds migrate and others do not? This question is fundamental to understanding how migratory systems are responding to environmental changes, but the causes of individual migratory behaviours have proven difficult to isolate. We show that, in a partially migratory population of Eurasian oystercatchers (Haematopus ostralegus), the migratory behaviour of progeny follows paternal but not maternal behaviour, and is unrelated to timing of hatching or fledging. These findings highlight the key role of social interactions in shaping the migratory behaviour of new generations, and thus the spatio-temporal distribution of migratory populations.
是什么决定了有些鸟类迁徙而有些鸟类不迁徙?这个问题对于理解迁徙系统如何应对环境变化至关重要,但个体迁徙行为的原因却难以确定。我们发现,在欧亚蛎鹬(Haematopus ostralegus)的部分迁徙种群中,后代的迁徙行为遵循亲代的行为模式,而与孵化或离巢的时间无关。这些发现突出了社会互动在塑造新一代迁徙行为以及迁徙种群时空分布方面的关键作用。
