Brent Goose

Branta bernicla (Linnaeus, 1758) BG BREGO 1680
Family: Anseriformes > Anatidae

Brent Goose, John Harding

Brent Geese are locally numerous winter visitors to Britain & Ireland, found on saltmarshes and adjoining grassy habitats around most of the coast.

Britain & Ireland host individuals from four separate breeding populations. The two Light-bellied Brent Goose populations – from Canada and Svalbard – largely winter on Strangford Lough and Lindisfarne respectively, while the birds wintering elsewhere in Britain come from the Russian Dark-bellied population. A few Black Brants, from Siberia, Alaska or Canada, are recorded most years.

Wintering numbers increased strongly through the 1970s and 1980s, and have fluctuated around this higher level since.

DISTRIBUTION

Brent Geese were recorded in winter from almost the entire coastline of Britain & Ireland, except for north and west Scotland. This overall distribution conceals separate patterns for birds from three different breeding populations. The Canadian Light-bellied population winters predominantly in Ireland. Birds from the Svalbard Light-bellied Brent Goose population winter in Denmark and in Britain, where they winter predominantly around Lindisfarne in Northumberland. The bulk of the Brent Geese that winter elsewhere in Britain are from the arctic Russian-breeding Dark-bellied population.
