The Red-breasted Geese fly about 8000 kilometers untli they reach their wintering habitats in Bulgaria and Romania.  The places for rest of the geese along their long route are not well studied yet, but researches are currently being implemented.  It is known that that the geese need water reservoirs in which they can pass the night peacefully. Along their route the geese also need appropriate pastures to feed and, which is most important, tolerant attitude from the local people. In most of the countries the hunt of Red-breasted Geese is forbidden. What can still be improved is the control of poaching and the level of public awareness.  
The most of the Red-breasted Geese fly along the Ob River and reach the coast of the Caspian Sea. From this point of the migration route about 80% of the world population of the species head west towards the Balkan Peninsula. Very few geese sometimes fly over the Ural Mountains and most probably such specimen have been observed in Hungary and Serbia. Some birds chose to stay at the coast of the Caspian Sea and others head for the Aral Sea. These groups, though, are very small in number.

Until the 50s of the previous century most of the Red-breasted geese were spending the winter in Azerbaidzhan. They changed their wintering areas and have chosen the region of Dobrudzha in Romania and Bulgaria (close to the Black Sea coast). The reason was that the traditional farming(which provided appropriate pastures for the geese) at the Caspian Sea coast was changed with cotton plantations.
