摘要: Summary. Coastal shorebird species overlap at many wintering sites or migratory stopovers. However, each is morphologically and physiologically specialised for reducing competition space, time habitat. A can encompass several populations, sometimes designated as subspecies. Differences between ages sexes within the same also lead to segregation individuals in a foraging area. In this study, we explored non-breeding spatial temporal two subspecies of black-tailed godwit Limosa limosa on central Atlantic coast France (the Pertuis Charentais). The proportions sex age populations were assessed explore differences distribution. L.l. islandica winters area from July March whereas may stopover during south- northward migration. occasionally some just afte...
