Summary:
The Iberian recoveries of Robins Erithacus rubecula ringed in the rest of Europe originate mostly from Northern Europe and are concentrated in southern Spain, as well as along the eastern Spanish coasts. The Balearic Islands constitute the main wintering area. Male recoveries are more abundant than female ones. The postnuptial migration occurs between September and November, but 75% of Robins migrate from the second ten-day-period of October to the second ten-day-period of November. Robins ringed in Finland, Sweden, the former Czechoslovakia and the Baltic Republics are mainly recovered in eastern Iberia, while those ringed in Norway, Denmark, Germany, British Islands, Netherlands and France migrate across the western Pyrenees mainly. Some of the birds migrating through this area, especially those coming from the easternmost breeding areas, may also follow the Ebro valley towards the Mediterranean coast. Robins coming from the populations of Northern and Central Europe show an autumn passage which is delayed as compared to other populations, but they migrate more rapidly across Iberia. The numbers of wintering birds are roughly constant throughout late November-mid February. Robins wintering in southern Spain come from northern Europe mainly, and those wintering in eastern Spain and the Balearic Islands originate mostly in more eastern and southern European areas. The proportion of recoveries of young birds decreases from autumn to winter, suggesting that such birds migrate farther than adults on average.
