Brent Geese Branta bernicla
The Pale-bellied Brent Goose (in the middle of three) shows the strong contrast between breast and belly compared with the more suffused and commoner Dark-bellied variety. Two races of Pale-bellied birds visit Britain from Greenland and Spitsbergen. There seemed to be only one Pale-bellied bird amongst a large flock of Dark-bellied ones feeding on land at Farlington Marshes.
Thank you all for your kind responses.
