Latitudinal-related variation in wintering population trends of greylag geese (Anser Anser) along the Atlantic flyway: A response to Climate Change?

The high quality of available census data for wintering greylag geese in Europe facilitates the study of how population change varies across the Atlantic flyway and relates to global change. Files contain information of greylag geese winter counts, mean January temperatures and surface areas of the main crops used by wintering geese (1980-2009), and of the first arrival of greylag geese in autumn to the Guadalquivir marshes (1961-2012).-- et al.
