Ad. Bonaparte's gull (L. philadelphia). 18-12-10. This is almost sure the same bird from last winter (6-1-10).

This bird was found the day 16-12-10 in the fishing harbour and has been seen today in the boat trip off Tarragona

1 cy Yellow-legged gull (L. michahellis), 27-12-09. Not all the big guys are Great black-backed :) The bills looks odd and when flying the moulted greater coverts are a lot for any other species out of michahellis.

2 cy Yellow-legged gull (L. michahellis), 27-12-09. The pale iris and the primaries suggest the ageing of the ndividual.
