(1) Many migratory birds are declining worldwide. In line with the general causes for the global biodiversity crisis, habitat loss, pollution, hunting, over-exploitation and climate change are thought to be at the basis of these population declines. Long-distant migrants seem especially vulnerable to rapid anthropogenic change, yet, the rate of decline across populations and species varies greatly within flyways. We hypothesize that differences in migration strategy and notably stopover-site use, may be at the basis of these variations in resilience to global change. (2) By identifying and comparing migration strategies of two very closely related shorebird species, the Curlew sandpiper (Calidris ferruginea) and the Red-necked stint (Calidris ruficollis), migrating from the same non-breeding site in Australia to similar breeding sites in the high Russian Arctic, we aimed to explain why these two species express differential resilience to rapid changes within their flyway resulting in different population ...
