Last week I mentioned an adult Mediterranean Gull that I saw on Charmouth beach, sporting a red plastic ring (PER3). Through the excellent Colour Ring Birding website, I reported the details and received the following information from the Polish scheme behind the ringing of this particular bird:
Ringed on 13/05/2007 as a 3rd calendar year female, nesting at Polder Bukow, Krzyzanowice, Slaskie, POLAND, by Jakub Szymczak
So the bird was two years old when ringed, which makes it 12 years old. This colour ring reading can become addictive!
