The Control that nearly "slipped through"

One of the last queries we received following submission of our historic data, was a Reed Warbler (that we caught in 1979) that had been ringed by Martin as a Sedge Warbler !!. On checking Martin's data books, and LRGp's retrap sheets the mistake was found. We recorded the number as KC87874, but when it was entered in BRING, it was "corrected" to KS87874 - as this was the sequence that Martin had been using in 1978 (and there were other captures in this sequence on the same day). Submitting the correct number produced the following -

Reed Warbler KC87874 was ringed at Beachey Head, East Sussex on 24 August 1975, and caught in RB1 on 26 July 1979 - 1432 days, 279 km, 299 degrees (a nice surprise for the current Beachey Head ringers).
