Summary: | In order to determine their breeding and moulting siteswe fitted eight Taiga Bean Geese Anser fabalis fabalisand two Tundra Bean Geese A. f. rossicus with satellitetransmitters in 2007–2009 at their spring roosting sitesat Umeå and Luleå, Sweden. Nine of these transmitterstransferred GPS positions for 1–4 months. All positionswere N–ENE of the catching sites. The Tundra BeanGeese migrated to Finnmark in Norway and neighbouringparts of Finland. The Taiga Bean Geese migratedto sites near Övre Soppero (Sweden) and Kautokeino(Norway) in the west, through northern Finland, to RussianKarelia. Three of five Taiga Bean Geese with activetransmitters flew to Novaya Zemlya to moult. Our resultsindicate that a significant proportion of the Taiga BeanGeese that migrate along the coast of northern Swedenin spring do not breed west of 20° E, and that many ofthem moult on Novaya Zemlya. The Tundra Bean Geesethat pass through northern Sweden in spring belong tothe Finnmark population that breeds slightly north of theTaiga Bean Geese.
