A soft, low 'moo-moo' — the murmuring call gives the Nene its Hawaiian name. Also gives honking calls in flight. Less vocal than Canada Goose; distinctive murmuring quality.
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
Hawaiian Goose
Hawaii's state bird and the world's rarest goose, recovered from near extinction. A medium-sized brownish goose with a black face, pale buff neck with diagonal stripes, and reduced webbing between the toes adapted for walking on lava. Grazes on volcanic slopes and coastal areas.
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.
