(1) Understanding how individuals and populations respond to fluctuations in climatic conditions is critical to explain and anticipate changes in ecological systems. Most such studies focus on climate impacts on single populations without considering inter- and intra-population heterogeneity. However, comparing geographically dispersed populations limits the risk of faulty generalizations and helps to improve ecological and demographic models. (2) We aimed to determine whether differences in migration tactics among and within populations would induce inter- or intra-population heterogeneity in survival in relation to winter climate fluctuations. Our study species was the Common eider (Somateria mollissima), a marine duck with a circumpolar distribution, which is strongly affected by climatic conditions during several phases of its annual cycle. (3) Capture-mark-recapture (CMR) data were collected in two arctic (northern Canada and Svalbard) and one subarctic (northern Norway) population over a period of 18, ... : Dataset_EastBay_CanadaData were collected annually in the East Bay Migratory Bird Sanctuary, Canada from 1996 to 2013. This txt file is the headed format directly usable in E-surge program (see E-surge manual and Appendix S2). Each line represents an individual capture history with 1 when it has been seen and 0 with it has not been seen. The 18 first columns are each year (e.g. A1996 for year 1996). The "S" column is the sample size (i.e. associated number of individuals) and the "RC" column is the right censoring column.Data_PrinsHeinrich_SvalbardData were collected annually on Prins Heinrich Island on the west coast of Svalbard from 1999 to 2013.
