Pelagic seabirds have evolved physiological and morphological characteristics that enable them to fly in an energy efficient manner over the oceans. Although there are some exceptions (e.g., Delord et al. 2020), most species come ashore only to breed or rest. However, recent tracking technologies have revealed some unexpected overland journeys. For example, brown pelicans Pelecanus occidentalis (Lamb et al. 2017), Arctic terns Sterna paradisaea (Redfern & Bevan 2020), and the focal species of this study, fledglings of streaked shearwaters Calonectris leucomelas (Yoda et al. 2017a; Fig. 1a), are known to migrate overland.

山区中上层海鸟的迁徙路线和存活率的年度变化

远洋海鸟已经进化出生理和形态特征，使其能够以节能的方式飞越海洋。尽管有一些例外（例如，Delord等，2020），但大多数物种只能上岸繁殖或休息。但是，最近的跟踪技术发现了一些意外的陆上旅行。例如，褐鹈鹕Pelecanus occidentalis（Lamb et al.2017），北极燕鸥Sterna paradisaea（Redfern＆Bevan 2020）和本研究的重点物种，斑纹剪力水的雏鸟Calonectris leucomelas（Yoda et al.2017a;图1a）。 ），据了解会向陆地迁移。
