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.
Cackling Goose
Breeds on low-lying Arctic and subarctic tundra. Winters on grasslands, agricultural fields, and coastal marshes in the central and western United States. Often found in mixed flocks with Canada Geese.
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.
Cackling Goose
A high-pitched, yelping 'luk-luk' or 'likl-likl' — higher-pitched and smaller-sounding than Canada Goose. Given rapidly in flock flight. Useful identification feature.
Geographic Range & Migration

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.
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.
