Red-breasted Geese breed in Siberia and the entire population migrate to western Black Sea coast, where it spend winter in Romania and Bulgaria. This goose is classified as globally threatened bird species, because of high winter concentrations at small areas and a lot of threats in the whole flyway. Red-breasted Geese were counted at their roost sites in Bulgaria and Romania between 1995 and 1999. They arrived in Romania in the second part of October, while in Bulgaria they started to arrive in the second part of November. The peak numbers (40 000-55 000) were usually recorded in Romania in November and December. Almost the whole population moved into Bulgaria during January-February when up to 62 600 were counted. Return migration started in February and by the end of March almost all had left the region.
