Over 1.1 million Sedge Warblers have been ringed in the UK but we handle very few. Out of only two ringed at Landguard in May this year one done on 7th May 2017 was retrapped 848km away on 3rd June 2017 at Sore Merkeskog, Utsira, Rogaland, Norway which is presumably somewhere near its intended breeding grounds. Out of these million odd Sedgies ringed by the UK ringing scheme since its inception only four have previously been recovered in Norway (with only five Norwegian ringed Sedgies having been recovered going the other way in this country) which would suggest that very very few Sedge Warblers fly back and forth over the North Sea.
