摘要

2015年和2016年，全球濒危物种小白额鹅(Anser erythropus)在春季迁徙期间被捕获并标记，占当时瑞典繁殖种群的近10%。其中两只鸟被跟踪了一个多季节。追踪数据揭示了一个出乎意料的广泛的迁徙通道和集结地网络。秋季和春季迁徙因踏脚石地点和迁徙速度的不同而不同。到目前为止，在丹麦、德国北部和瑞典发现了未知的主要中途停留点。通过动态布朗桥运动模型，描述了小白额雁在迁徙过程中可能使用的区域，并强调了保护意义。这项研究为描述小白额鹅在西欧的迁徙之谜提供了另一个重要的线索。

Migration routes and stepping stones along the western flyway of Lesser White-fronted Geese (Anser erythropus)

Summary In 2015 and 2016 four Lesser White-fronted Geese (Anser erythropus), a globally threatened species, were caught and tagged during spring migration representing nearly 10% of the entire Swedish breeding population at the time. Two of the birds were followed over more than one season. Tracking data revealed an unexpected wide network of migration corridors and staging sites. Autumn and spring migration differed by stepping-stone sites and migration speed. So far unknown key stopover sites were discovered in Denmark, northern Germany, and Sweden. By using dynamic Brownian bridge movement models, the potential areas that Lesser White-fronted Geese used during migration are described and conservation implications spotlighted. This study provides another important piece of the puzzle describing the migration of Lesser White-fronted Geese in Western Europe.

期刊介绍： Bird Conservation International is a quarterly peer-reviewed journal that seeks to promote worldwide research and action for the conservation of birds and the habitats upon which they depend. The official journal of BirdLife International, it provides stimulating, international and up-to-date coverage of a broad range of conservation topics, using birds to illuminate wider issues of biodiversity, conservation and sustainable resource use. It publishes original papers and reviews, including targeted articles and recommendations by leading experts.
