Leiden, Beestenmarkt, The Netherlands, November 28, 2010. ex Y[2.M] (Arnhem 3580861) Adult Black-headed gull in full winter (basic) plumage. Back in Leiden to spend another winter. Unsurprisingly, this gull has lost its colour ring on its left leg, which was already heavily damaged the previous winter.

Beestenmarkt, Leiden, 28 november 2010. ex Y[2.M] (Arnhem 3580861) Adulte Kokmeeuw in volledig winterkleed, terug in Leiden om de winter door te brengen.

Leeftijd: 1ste kalenderjaar.)
