1 w. possible Yellow-legged gull (L. michahellis), 3-3-07. The tail pattern is the only objective thing pointing to YLG. The moulted coverts do not show the YLG sequence and the fact that some secondaries are lacking and the new central tail make possible a replacement (and no moult) of the coverts. However, the tails is very white with a defined black band. Alltogether make sense identify the bird s a odd pale michahellis.
