I've just had an E-mail back from Renaud F from Brussels in Belgium, who originally ringed the adult Mediterranean Gull I saw on the Link's road car park at Lowestoft on 15th November this year. The bird had a green ring on it's right leg with the white lettering 3XA9 on it.
This is the second time I have seen this bird, having previously seen it at the same site on 28 December 2007.
Renaud originally ringed the bird as a 3rd calendar year bird on 17th May 2004 at Noordelijk Insteedkdok, Oost-Vlaanderen, Belgium where apart from deviating to Calais (Aug 2004) and Antwerp (April 2006) it has commuted regularly between Noordelijk Insteedkdok (generally summer months) & Lowestoft (generally winter months).
The bird has now therefore reached the grand old age of 8 years old!
Ringing is vital in tracking the movements of birds, increasing our understanding of their movements and leading hopefully to better conservation of the species and the habitats they require.
