About These Birds
Red-breasted Goose
A small strikingly patterned goose with a vivid chestnut-red breast and face patch, black-and-white body, and white flank stripe. Breeds in Siberian tundra; winters mainly around the Black Sea. One of the most colorful and endangered geese, threatened by hunting and agricultural changes at wintering sites.
