There has been an "odd" white gull reported from the salinas at Tavira in the eastern Algarve for the past three weeks or so. I have been sent numerous distant, digiscoped (and mainly 'orrible) shots from various people for my opinion. The photos looked so different that I found it difficult to believe that they were of the same bird.
The attached photo is the first decent shot I have seen; it was taken by Peter Dedicoat on 14th May and has been identified as a leucistic individual. I won't say which species, but would like opinions as to what you think it is (are you there Jan?).
Thanks in anticipation,
