Overview

Brent Geese are small, dark, compact geese from the Russian Arctic. The Dark-bellied race (the race seen on the Sefton Coast) has a sooty-brown underside and a small white neck patch. They feed on the tidal flats of the Ribble Estuary and use the saltmarsh vegetation. Their numbers reflect the health of Arctic breeding conditions — bad breeding years show up as low wintering numbers. They give a quiet, rolling 'rronk' call.

Small, dark goose. Black head, neck and breast. Dark brown body. Small white neck collar (variable). White stern. Dark belly (Dark-bellied race). Much smaller than other geese.

Walk the sea wall toward Crossens in winter and scan the tidal channels. The dark, compact shape and dark belly distinguish them from other grey geese at distance.

Frequently Asked Questions

Why are there two types of Brent Goose?

There are two races of Brent Goose: Dark-bellied (Branta bernicla bernicla) from Russia, which winters mainly in eastern England, and Pale-bellied (Branta bernicla hrota) from Svalbard or Canada, which winters mainly in Ireland and northeast England. On the Sefton Coast, Dark-bellied birds predominate. A third race, Black Brant from North America, is a rare but annual vagrant worth checking for in any Brent flock.
