Bird migration in space and time: chain migration by Eurasian curlew (Numenius arquata arquata) along the East Atlantic Flyway
Migration patterns in birds vary in space and time. Spatial patterns include chain, leap frog, and telescopic migration. Temporal patterns such as migration duration, number and duration of stopovers may vary according to breeding latitude, sex and season. This study aimed to verify these patterns i...

Curlews displayed chain migration, because wintering curlews maintained the latitudinal sequence to their breeding sites. Southern curlews had a longer nesting period due to their earlier arrivals. While spring arrival at breeding sites did not differ between the sexes, in autumn females departed earlier than males. Migration duration and distance, as well as stopover number and duration showed a significant increase with breeding site latitude but did not differ between the sexes or between spring and autumn migrations, suggesting that curlews took a comparable amount of time migrating during both seasons. The high site faithfulness in curlews suggests that rapid autumn migration allows them to return to defend their winter foraging areas.
