Simon,
While I wouldn't know a Black-tailed Gull if it fell on me, I'm rather perplexed by your response to Geoffrey's photos. How can it be a young Silver Gull if it has pale (yellowish) legs and a pale yellow black tipped bill. My Field Guide ( Michael Morcombe) shows a juv Silver-Gill as having dark (brown) legs and a dark (blackish) bill.
My Field Guide also gives the size of a Silver-Gull as 39-42 cm and a Black-tailed Gull as 45-48 cm. The difference of some 6 cm is hardly 'almost twice the size' as you indicate in your e-mail.
Grateful your advice
Mike

Thanks, Simon. The problem of not seeing the whole bird, then. I suppose I?ll just have to keep looking! Geoffrey

Geoffrey,
Sorry, you can ignore my previous request. I just found the images you posted. Unfortunately, the bird is just a young silver gull. Black-tailed gulls would be almost twice the size with bright yellow and much heavier bills.
All the best,
Simon.
