From: Flyway connectivity and exchange primarily driven by moult migration in geese
a Ringed and tagged greater white-fronted geese being released in Hungary 2016/17. Overlap regions (red cells) and GPS tracks (red for North Sea population, green for Pannonic population) towards and from those regions during (b) spring migration (North-Western Kazakhstan), (c) moult (Pyasina delta) and (d) autumn migration (Pyasina delta, Gydan peninsular, Bely island and Yamal). See outlines of those regions indicated in Fig. 1 a, c, d. Note that overlap regions in (b) are in the top-right and bottom-left corners of the map. GPS tracks are not clearly separated by population at this scale
