1. Spatio-temporal variation in population dynamics of migratory populations is shaped by exposure to different environments during the annual cycle. Hence, exposure to similar environments should translate into synchrony in vital rates. Despite a wide-ranging breeding population, the Baltic/Wadden Sea flyway population of eiders (Somateria m. mollissima) shares wintering grounds in the southern Baltic Sea, inner Danish waters and the Wadden Sea; different colonies within this flyway population are therefore likely to exhibit some degree of synchrony in vital rates. 2. Here we used capture-recapture-recovery data to investigate the impact of hunting, winter climate (the North-Atlantic Oscillation Index), winter temperature, nitrogen runoff, autumn-winter body condition of blue mussels Mytilus spp., natural predation and epidemic disease (avian cholera) on annual survival of adult females in ten study colonies distributed between the Netherlands and Finland. Moreover, we tested how the degree of similarity in ... : Long-term capture-recapture-recovery data on eider females from ten different colonies belonging to the Baltic-Wadden Sea flyway population. Encounter histories were compiled and prepared in a Live-Dead format for Program MARK. Environmental covariate data is in the Covariates_DRYAD.xlsx-file. Spatial recovery data of eider females in Recoveries_DRYAD.shp. ...
