The Red-Breasted Goose (Rufibrenta ruficollis) is native to Russia and is found in the northern areas of West-Central Siberia. Its breeding areas include the tundra and peninsulas of Yamal, Gludan and Taymyr. Until the late 1960s, the main wintering areas were along the southwest and south coast of the Caspian Sea. After that, as a result of worsening conditions in the area, birds moved to winter around the Black Sea, mostly in the Bulgarian and Romanian parts of Dobrudja. Before reaching their Balkan wintering places Red-Breasted geese fly over the North Prichernomorie. Along the south Bulgarian coast the flocks of up to 200 specimens are found. Occasionally single specimens and small flocks are recorded along the seashore of Turkey. The first migrating geese arrive along the Black Sea coast at about the end of September and beginning of October. Migration peaks in late November and early December. They remain there until they leave the wintering areas in March and fly to their nesting places.
