First post on gulls

This is my first post in this blog. I have tons of material to publish and I will start with the most recent, regarding gulls.

I've been in Portimão from the 7th to the 9th of September 2012 and went for some rings.

On the 7th I managed to get to the Barlavento landfill for a couple of hours and controlled 4 lesser black-backed gulls and one yellow-legged gull.
Two of the LBBG were ringed at Guersey by Paul Veron:  7N4  and  6AM6 
One from Zeebrugee Belgium (IMBO):  H.VAG    I found this one exactly in the same spot on the 20-01-2012
One from Moerdijk, Holand (Roland-Jan Buijs):  G3 

The yellow-legged gull was ringed in Spain but I still don't know who ringed it  3PV
