Yellow-legged gull (Larus michahellis atlantis)
Pictures of different ages of the sp. atlantis. I use
michahellis as family name, someone will perhaps call it argentatus og
cachinnans.
No further comments of
these thaxa here. (See link below.)
All pictures from the Canary island Lanzarote last week of januar
2001.

First winter flying. The gump of the tail clear white, not visible here.
