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.
