I've never come across these before. But hold on, I'll check my pictures - yes I have, at Wells Next the Sea! I just didn't know that they were different from ordinary Brent Geese! In fact, I find that I haven't photographed a Pale Bellied Brent Goose. Oh well, an excuse to go looking for them, I suppose.
Hi Simon, this is a quote from the RSPB site
"Main concentrations of dark-bellied birds in the Wash, the North Norfolk coastal marshes, Essex estuaries, the Thames Estuary and Chichester and Langstone Harbours. Most light-bellied birds are found at Strangford Lough and Lough Foyle, N Ireland and at Lindisfarne, Northumberland".
However I'm sure they do mix elsewhere though.

I believe and I'm open to correction here, that Brent Geese are split into 3 sub-species and are either:-
1) Dark Bellied
2) Light Bellied
3) Black Brant
There is no other type, in the UK anyway.
