Hardly a rarity, but a first for me in this neck of the woods. Nine of these magnificent birds decided to stop off at Pebley Reservoir, which is near to where I work in Barlborough, North Derbyshire. The only other Whoopers I've ever come across were at Wigtown in South-West Scotland.
According to the RSPB website they should be on their way back to Iceland for the summer after wintering somewhere in East Anglia (probably). Or maybe they have been to the European mainland - dunno if they migrate that far though?
