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).
