Massive mortalities of seabirds

Annual mass migrations of seabirds between their breeding and wintering grounds are critical for ensuring their survival and reproductive success. It is essential to comprehend the factors affecting their migration patterns and physical condition to facilitate conservation efforts. This study focuses on the mass mortality of two alcid species, the Razorbill (Alca torda) and the Atlantic Puffin (Fratercula arctica), along the Andalusian coast of Spain during the winter season of 2022-23.海鸟在繁殖地与越冬地之间开展的年度大规模迁徙，是维系其生存与繁殖成功的关键环节。 厘清影响其迁徙模式与身体状况的各类因素，对于推进物种保护工作而言具有至关重要的意义。 本研究聚焦2022-2023年冬季西班牙安达卢西亚沿岸发生的两种海雀科（alcid）鸟类大规模死亡事件，涉及物种分别为刀嘴海雀（Razorbill，学名Alca torda）与大西洋海鹦（Atlantic Puffin，学名Fratercula arctica）。
