The first control of Mediterranean gull L. melanocephalus of this Autumn

On the 14th there were about 60 med gulls at Algés Harbour mostly 1st and 2nd winters and also a few adults. I controlled about 40 individuals for rings (the remaining were sitting in the water) and only one was ringed:
 Green   1Z4   This individual was ringed in France, on Barbâtre, Polder de Sebastopol, Vendée by team Matthieu Vaslin and Cap Ornis Baguage  in 2009.
It had been in Portugal previously in it's first winter and was controlled by Stuart Mckay.
