Spring migration routes of Long-tailed Skuas around and the UK - results of observational and tracking data

摘要

In 2013 a record spring passage of Long-tailed Skuas Stercorarius longicaudus was observed in Scotland, including an unprecedented overland movement. Tracking data for the species has also hinted at overland migration in Scotland. Here, the tracking data are reviewed and the spring passage status of Long-tailed Skuas in the UK assessed, with a particular focus on observed overland movements, and first-hand accounts of major movements in spring 2013.
