Hudsonian Whimbrel, Simon Gillings

The Hudsonian Whimbrel is the north American counterpart of the Whimbrel normally encountered in the UK. For a long time it was considered a subspecies of Whimbrel and has only recently attained full species status. There are subtle differences in plumage tone but the main distinguishing feature is the dark rather than white rump. It is a rare vagrant to the UK, first recorded on Fair Isle in 1955, with fewer than 20 records since.
