Habitat Comparison
Brent Goose
Breeds on high-Arctic tundra; winters on estuaries, coastal mudflats, saltmarshes, and sea-grass beds along Atlantic and Pacific coastlines. One of the most strictly coastal wintering geese.
Höckerschwan
Lakes, slow rivers, estuaries, and coastal lagoons. Often associated with parks and ornamental waters in Europe.
Song & Call Comparison
Brent Goose
A low, guttural 'rronk' or 'ronk-ronk' from flocks. Soft nasal calls in feeding groups. A subtle, understated call for a goose — less loud than most Anser 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.
Geographic Range & Migration
Brent Goose
Breeds across boreal and subarctic Canada and Alaska; winters in the southern United States, Mexico, and Central America.
Höckerschwan
Native to Europe and western Asia. Introduced to North America, South Africa, Australia, and New Zealand.

About These Birds
Brent Goose
A small dark-bodied goose with a black head and neck, small white neck patches, and pale grey belly. Migrates between high-Arctic breeding grounds and temperate coastal wintering areas. Feeds on eel-grass and saltmarsh vegetation in winter. Three subspecies differ in belly coloration.
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.
