Dark-bellied Brent Goose

Hi Mark, being a bit of a novice is the Dark-bellied Brent Goose a recognised sub-species or a local variation. Your advice would be gratefully received. Regards Chris.

Brent Geese subspecies

Dark-bellied (B. b. bernicula - from Russia/W Siberia), Pale-bellied (B. b. hrota - from Svalbard, Greenland) and Black Brant (B. b. nigricans - E Siberia, Alaska, NW Canada) are the three subspecies of Brent Goose. All occur in Britain and Ireland, though Black Brant is a rare vagrant, usually mixed in with large flocks of Dark-bellied Brents. Nick Moran.

Brent Goose forms

The three forms mentioned by Birdtrack are widely accepted as subspecies of Brent Goose - and have been proposed as species in their own right (eg. they are treated as separate species by the Dutch authorities).

There is also a fourth form, Grey-bellied Brant, with a restricted breeding range (Melville and Prince Patrick Islands), but this form has yet to be widely recognised - and (as far as I know) has not yet been 'officially' named. This form has been recorded in Ireland.
