Mystery Gull

Following gull seen this evening in fading light at Broadsands Beach, Paignton by author and Jake Wood, we are struggling with the I.D, suggestions please!

EDIT @ 23:15 - My enormous fortune would go on 2nd-summer Iceland Gull, Bill    (Gavin)

Thanks Gavin, that's what we thought but in July! We went looking for Med Gull & YLG!! Cheers Bill
