Connectivité globale pour Pipit des arbres

The overall direction of movement is northeast – southwest. Birds breeding in West-Europe migrate through France and Spain to Africa, while more easterly breeders migrate through Central Europe and Italy. As a result, birds of West-Europe winter more westerly in Africa than birds of Central Europe and Finland, although there are not many sub Saharan recoveries to support this. Norwegian birds mostly migrate over the western part of the European continent, a minority cross the North Sea and migrates through Great Britain.

Birds breeding in West-Scandinavia are mostly recovered in South-West Europe in September, while more easterly Scandinavian birds are recovered in Central Europe and Italy in September. Several May-recoveries of eastern scandinavian breeders in Central Europe and Italy indicate that these birds use the same route in spring. Birds breeding east of Germany are recovered in Italy in September and October.
