Migration routes of Eurasian Curlews (Numenius arquata) resting in the eastern Wadden Sea based on GPS telemetry

摘要

The Wadden Sea is an important resting site on the East Atlantic Flyway for Eurasian Curlews (Numenius arquata). However, there is currently little information regarding the connectivity between breeding, staging, and over-wintering sites. We equippedfour Curlews with GPS-data loggers and recorded their migration patterns during 2014-2015. Curlews left the Wadden Sea during April and migrated to their breeding grounds in (north-) eastern Russia within 2-4 days. All individuals remained in the breeding area for 51-53 days, and then returned to the same place in the Wadden Sea where they had been caught, indicating high site fidelity.
