About These Birds
Cackling Goose
A small version of the Canada Goose with a stubby bill, rounded head, and shorter neck. Long treated as a subspecies; now recognized as a separate species with four subspecies. Migrates from Arctic breeding grounds to wintering areas in the central United States. Gregarious; mixes with Canada Geese in winter.
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.
