8C

I know it is not a very special image, but that is not why I am posting it. No, look closely to the gull's left leg, where you'll see a ring with the code '8C'. That code tells us it was ringed back in 2011 in the Port of Rotterdam, a few months later was spotted in France, and earlier this year it lived in Spain. And this morning centre of Rotterdam.

A glimpse of a gull's life. Fascinating, is it not?
