The intensity of geese migration has increased since 2005, and its routes have shifted eastward. The main migration route of the geese previously passed over the northwestern Sea of Okhotsk, far from the coast; since 2005, however, a major migration flow has been recorded over northern Sakhalin and the main-land part of Tatar Strait. A probable factor accounting for this shift is a change in weather conditions and, in particular, in the circulation of air masses over the northwestern Sea of Okhotsk.
