A report of a Sedge Warbler ringed by the Group on July 25th this year and caught 12 days later in Kent 412 km SE set me looking at all the similar quick recoveries we have for this species. Over the years we have ringed just over 14,000 Sedge Warblers which has produced 172 recoveries most at ringing stations on the south coast with some further a field in France (51)Spain (3) Portugal(1) and Senegal (1).
Our quickest mover was one ringed on August 13th 2004 at 10.00 and caught next day at Coventry at 05.50 a distance of 220 km. Sedge Warblers are night migrants so this gives some idea as to how far they can fly in a night. It weighed 12.7 gms at ringing but only 11.7 on re-capture.
Of other short time(under 10 days) recaptures we have two each at 4 and 5 days,4 at 6 days and one each at 9 and 10 days all along the south coast from Devon to Kent. Other than one in late July all the others were ringed and re-caught in August. Not all the birds we ring are local birds for we have caught three ringed in Perthshire ,two 7 days previously and one 14 days.
Two short time recaptures from France were 6 days after ringing, a distance of 677 km and 12 days a distance of 563 km. Remember most of these are young birds making their first migration at around three months old. Amazing!
