Red-breasted Goose
Breeds on river-terrace tundra in northwestern Siberia, often near Peregrine or Rough-legged Buzzard nests for protection. Winters on agricultural steppes and lake margins around the Black Sea and Caspian Sea.

A high-pitched, rapid 'kik-kik-kik' call. More vocal during migration; flocks give constant chattering. Considered a more squeaky, high-pitched call than other Branta geese.
Höckerschwan
Despite its name, not truly mute: gives hissing snorts and low grunting when threatened. Wings produce a loud rhythmic whistling throbbing sound in flight.

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.
Höckerschwan
Der Höckerschwan gehört zu den schwersten flugfähigen Vögeln; Männchen können bis zu 14 kg wiegen. Trotz seines englischen Namens („Mute Swan“, stummer Schwan) ist er keineswegs stumm und gibt zischende, grunzende und schnaubende Laute von sich. Höckerschwäne gehen lebenslange Paarbindungen ein, und ihre aggressive Verteidigung des Brutreviers ist bekannt.
