Pale bellied Brent at Bunessan October 2010

some more information 
This goose was ringed in SW Iceland in May 2007 and over winters in Ireland, it has made the journey several times but on this occasion it was blown east onto Mull. It will continue its journey after a few days of feeding and rest.
These hrota pale-bellied brent are from the East Canadian High Arctic flyway population. They breed up amongst the polar bears very far north in Canada, and over winter mainly in Ireland, although some birds also go to western GB, the Channel Islands and France (mainly Normandy). They stage for a considerable period in spring and autumn in Iceland, and have a hazardous trip over the Greenland Icecap in between. The current flyway population is of the order of 40,000 birds.
The current ringing programme commenced in 2001. Ringing mainly by canon-netting in Ireland, and on the spring migration in Iceland in May. One expedition has been mounted to catch birds in Canada, when about 200 birds were caught whilst flightless (herded by helicopter!!). Overall we have now caught over 3,500 geese, so it is well worthwhile checking out any flocks you might come across for leg-rings. Currently re-sightings are reaching about 10,000 records per year from the wintering grounds, and a further 5,000 from Iceland in spring and autumn.
