Common Gull - WHITE, M[Gdansk FN 04302] / Blue, Red, Blue

Common gull (Larus canus), 15th calendar year
Warmond, Zwanengat, The Netherlands, Februari 21, 2009. White, M[Gdansk FN 04302]/Blue, Red, Blue. Adult Common Gull in full winter (basic) plumage. This bird was observed breeding in Poland in 1999 and 2000, but in 2006 it was observed breeding in Germany. Considering the high breeding site fidelity for Common Gulls, this is very unusual.
(Ring info: ringed May 24, 1995, near village of Kobylnica, Poland. Age: pullus.)

Stormmeeuw (Larus canus), 15de kalenderjaar
Zwanengat, Warmond, 21 februari 2009. Wit, M[Gdansk FN 04302]/Blaauw, Rood, Blaauw. Adulte Stormmeeuw in volledig winterkleed. Dit individu is in 1999 en 2000 broedend waargenomen in Polen, maar in 2006 in Duitsland. Gezien Stormmeeuwen erg plaatstrouw aan het broedgebied is dit gedrag erg ongebruikelijk te noemen.
(Ring datum: 24 mei 1999, nabij Kobylnica, Polen. Leeftijd: pullus.
