For the time being, I will leave the photo of the Black-headed Gull on the site 
but query it. I hate trying to identify from poor photos, particularly at odd 
angles...and for what is essentially an easy bird to tell from Silver Gull, 
normally.

Darryel - if you are reading this, did you get any other shots?

Regards,

Simon.
