1 w. Mistery gull (Larus sp.) 27-1-13

This individual does not fit to any of the species the bird ressembles, Herring gull (L. argentatus) or Yellow-legged gull (L. michahellis). For the first, the primary pattern is not the right one, since the white spots on the outer web of the inner primaries is well defined and not difus at should be, in addition, the outer greater coberts became not much pattern at the base, the head is massive and white with a obvious shadow around the eye. For Yellow-legged, the birds shows a wrong backround colour, more Herring gull-like, the primary projection is short, the black of the base of external tail feathers is very wide and not well-defined and the tertials show a "biten" design and the underwing design is very soft. In addition the post-juvenile moult is very restricted, no including any covert, and it looks like maybe even some old scapulars are left...

Many thanks to Chris Gibbins for comments on the bird!!

Any additional comment will be welcomed.

2 w. Yellow-legged gull (L. michahellis), 09-01-11

2 w. Yellow-legged gull (L. michahellis), 09-01-11. A very pale and plane individual.

Near adult or adult Lesser black-backed gull (L. fuscus), 09-01-11

Near adult or adult Lesser black-backed gull (L. fuscus), 09-01-11. This individual has dark eyes. Maybe this is a rest of immaturity, as the bill has also some dark tracks and the legs are pink. It is not obvious if the wing coverts also show immaturity, but there is a lot of white in primarues. Maybe this is just an odd bird.

2 w. Cantabric Yellow-legged gull (L. michahellis lusitanius). 08-01-11. This is one of the few records (the 4rth) of Yellow legged gulls of Cantabric origin in the Mediterranean. Since field identification is not possible, the rings are necessary to ensure its origin. Picture and record by Raül Aymí.
