Hi

What do you think about this gull? Eric Christen observed it yesterday 9.11. in Zürich, Switzerland.
Thank you for your help!

Kind regards

Hi

Today I saw a hybrid Yellow-legged x Lesser Black-backed Gull at Yverdon (Lac de Neuchâtel), Switzerland. It was born at the same lake last year and then ringed with a ring at each leg.

Hi I'm not a gull expert and I don't have experience with AHg except this possible smithsonianus 2007 in Switzerland: http://www.pbase.com/dinah_saluz/goeland_probable_smithsonianus_ And I don't have much experience with Hg as there are only little numbers wintering in Switzerland, but I can cite so...

Good gulling

Good gulling

Hi everybody I'm from Switzerland. And here I have exactly this problem with second winter Herring and Yellow-legged Gulls, because in winter Herring Gulls are nearly as common as Ylg at the Bodensee.
