Black-headed Gull WHITE [E5RE] / black

Black-headed gull (Chroicocephalus ridibundus), adult
Leiden, Zijlpoort, The Netherlands, December 5, 2010. W[E5RE] (Arnhem 3693322). Adult Black-headed gull in full winter (basic) plumage. This is an individual from the nearby colony in Zoetermeer, see this image of this gull in full summer (basic) plumage, taken in July 2010.
Interestingly, the outline of the hood is starting to show, indicating that the moult has already commenced (compare with the image taken 12 days earlier. Only a small minority of adult Black-headed Gulls start their moult this early, the norm is January/February.
(Ringing date: June 2, 2010, Benthuizerplas, Zoetermeer, The Netherlands. Sex: unknown. Age: unknown, older than 2nd-calendar year.)

Kokmeeuw (Chroicocephalus ridibundus), adult
Zijlpoort, Leiden, 5 december 2010. W[E5RE] (Arnhem 3693322). Adulte Kokmeeuw in volledig winterkleed. Dit individu is afkomstig uit de kolonie in Zoetermeer. Zie deze foto van de meeuw in volledig zomerkleed, genomen in juli 2010.
Interessant om te zien is dat de omlijning van de kap al zichtbaar begint te worden, wat betekent dat de koprui al gestart is (vergelijk met deze foto 12 dagen eerder genomen. Slechts een minderheid van adulte Kokmeeuwen ruien hun kap zo vroeg in het winterseizoen; de norm is dat hiermee pas in januari/februari begonnen wordt.
