Connectivity patterns and key non-breeding areas of white-throated bluethroat (Luscinia svecica) European populations

摘要: Connectivity patterns and key non–breeding areas of white–throated bluethroat (Luscinia svecica) European populations.— Using ring recovery data from the EURING databank, aims this study were: (1) to identify chief migration wintering subspecies, L. s. namnetum, cyanecula azuricollis, (2) evaluate degree connectivity between breeding regions determine each (3) whether are sufficient answer previous questions adequately. Most recoveries were obtained during autumn period (n = 155, 68.9%), followed by winter 49, 21.8%) spring 21, 9.3%). For we did not find any at more than 100 km in or spring, there none all winter. All analyses thus relate namnetum. Both subspecies move across a NE–SW axis their within circum–Mediterranean region, mainly Iberia, following population–specific parallel routes. namnetum uses Atlantic coastal marshes France south–western where found. cyanecula, however, both Mediterranean wetlands autumn, but only those giving rise loop–migration pattern. Telescopic was demonstrated for cyanecula. Recovery insufficient detail entire range populations. Technologies such as use geolocators will play relevant role scenario.
