About These Birds
Ashy-headed Goose
A medium-sized sheldgoose with an ash-grey head, chestnut breast, black-and-white barred back, and bright orange legs. Found in temperate forests and grasslands of southern South America. Migratory; breeds in the south and winters northward through Chile and Argentina.
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.
