Yesterday was seen this gull in the Manzanares river, in Madrid city.
The picture was made by Mercedes Fernandez.
We belive that can be one Larus argentatus argentatus, but we are not sure.
Any opinion?

Yesterday I saw this Gull at L'Albufera, Valencia, Spain, Mediterranean coast of Spain.
I belive that is one second winter, but never I saw one LBBG of this age with this plumage.
Some suggestion?.

Here are pictures of one inmature of Audouin Gull in one landfill site of Valencia.
Is this gull leucistic or.... ?

Thank Ruud,
This it was my first impression when I saw her, but I had doubts later on having looked at the photo.

Can be this gull one juvenile of LBBG?
I am not sure.

Our friend Óscar Frías sigthed this gull at 05-03-10 in Talavera de la Reina, Toledo, Spain.
We do not know which is the species.
It seems that the gray feathers of the mantle are not so dark as show off to be in the photos.
We think that it can be a herring gull, but we have doubts.
Some suggestion?

The correct date is 25-01-10.

Pictures of one hibrid of Larus canus x Chroicocephalus ridibundus at Pinto, Madrid, Spain.
Have been seen at 24-01-10, by Carlos Andrés & Javier Marchamalo.
Any suggestion?.

When I saw this gull I annotated YLG of second winter, but now I have seen that your legs are pink.
Too, I belive that has the terminal band of the wide and white tail, in YLG would be totally black.
Is possible that was one HG of third winter?. I am not sure.
Some suggestion?

The last Wednesday I saw in Madrid this gull.
I belive that can be one Herring Gull of second winter.
It's possible?.
