Brent Goose (Dark-bellied)
|Scientific name:||Branta bernicla bernicla|
A rare winter visitor from Siberia from October to March.
Very similar to the much commoner Light-bellied Brent Goose and care is needed to separate the two species. Dark-bellied Brent can identified by the darker and much more extensive grey colouring on the flanks and back. The white flank patch that is very obvious in Light-bellied Brent Goose is reduced to a stripe along the flanks. Juvenile Light-bellied Brent similarly show a lack of a white flank patch, however these have extensive white barring on the back, which is not shown by adults.
Indistinguishable from Light-bellied Brent Goose.
Favoured food is eel-grass found in coastal estuaries. Dark-bellied Brent Geese also feed on other estuarine plants such as glassworts and sea aster, and to a lesser extent grasses and cereals
Dark-bellied Brent Geese breed in the tundra of northern Siberia
The majority of Dark-bellied Brent Geese winter in the Netherlands, northern France and the United Kingdom. This sub-species is a rare winter visitor in Ireland, where it associates with Light-bellied Brent Geese at coastal sites (mainly estuaries)
