The Radde's Warbler Phylloscopus schwarzi nests in Southern Siberia to the east of Novosibirsk and winters in Southeast Asia. Normal autumn migration involves a long eastward route before bifurcating south. However, each year, some individuals seem to be wandering in Western Europe, several thousand kilometers from their nesting and wintering areas. Most of these birds arrive in Europe via southern Scandinavia in early October, and then continue along the coasts and arrive in Belgium in mid-October before continuing their journey to Spain. A smaller cohort appears to arrive in Western Europe via the central Europe.We analyze these observations in the light of knowledge about the mechanisms that could explain the deviation in the migratory paths of Siberian passerines.
