2nd CY LBBG in juvenile plumage

On January 30 2011, a 1st winter Lesser Black-backed Gull was seen in Leiden, the Netherlands. As far as I can see, the gull seems largely in juvenile plumage. While many of the upper scapulars have been moulted to second generation, the lower scapulars appear juvenile. As far as I can see also all ...

Re: Black-headed Gulls with gray hind neck

Hi Maarten, Somehow I did not note the gray before, but going through my pics I found one BHG with a very similar pattern. It is clearly visible on photographs made on Dec 22, 2009 In Leiderdorp, The Netherlands. The gray pattern is retained for a year as it is still visible on photos made on Dec 5,...

Re: Leiden 14-02-2010

Hi Theo, Fully agree. I happened to be in Helsinki two weeks earlier, and photographed almost all (!) Herring Gulls in the harbor, which were only very few as the harbor was largely frozen.... One metal ring read, a 2nd CY, ringed as pullus 30 km from Helsinki. Some photo's: here http://www.pbase.co...

Leiden 14-02-2010

Although not yet matching Amsterdam, Leiden was not too bad either last weekend. Common Gull from Estonia, Herring Gull from Finland, and Black-headed Gull from Poland.

Here some pics from Feb 14, 2010.

Re: Hybrids fuscus x argentatus

Beste Ruud,
Ik heb je foto's met veel interesse bekeken.
Deze dieren lijken sterk op 'mijn' IJmuiden vogels.
Erg leuk!
