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 in a long-distance migrant, the Eurasian curlew (Numenius arquata arquata), and to provide a synopsis of spatio-temporal migration patterns in this species of concern throughout the East Atlantic Flyway. We tagged 85 adults with GPS-data loggers in Germany, Poland, France, and Estonia between 2013 and 2019. We computed the distance flown, linear loxodromic distance, duration, stopover number, total stopover duration, mean stopover duration, departure time, and arrival time for 177 out of 187 tracks. On average (± standard deviation), spring migration occurred from April 4–14 (10.2 ± 8.4 days), curlews flew 3,623 ± 1,366 km, and had 5.8 ± 3.6 stopovers, with a duration of 29.4 ± 38.2 h per stopover, while autumn ...
