Herring is right. There is other gull that look's like a Blacked backed Gull, I don't know if it is a lesser or a greater. There's a Shorebird out there to and looks to have alot of red on the neck, maybe a Red knot.

Pic one is an adult herring gull and a 3rd cal year Greater Black-backed. The 2nd pic shows an adult Greater Black-backed gull, 1st year common (mew) gulls and black-headed gulls. In my opinion.

I too, although I don't know enough about Mew/Common gulls to agree there. I also believe that the waders in front are Black-tailed Godwit. Look at that gorgeous color!

Pic 1. shows 2 herring gulls (an adult and a sub adult) with the dark gull in the center being an immature Great Black backed gull. The small dark headed gulls are Black headed gulls.
Pic 2. shows An adult great black backed gull on the right. and two juvenile Lesser Black Backed Gulls. The waders are black tailed godwits.

Check tertial, greater coverts and overall pattern the two juvenile gulls in pic.2 and compare with these two:

Landrover, it does exactly what it says on the tin
Appreciate the responses and thanks for the link JanJ
How do you explain the uniform greyish greater coverts visible on right bird ?
The rest is typical of Common, especially the pattern of the tertials.

Definitely not common gull? - yet it is a lesser black-backed? maybe it's my monitor, but there is no way these immatures are even 2/3rds large enough to get anywhere near lesser black size.

So much work, so little time...so let's go birding
Hi All,
Though I've got no first hand experience with nominate canus Common Gulls, I must say that the two mystery gulls in the second picture sure resemble images of juvenile Common Gulls. Those pale fringed, dark centered scapulars are imparting a rather young LBBG-like upperpart pattern, but otherwise, the features seem to me to fit canus better. As already mentioned, the greater coverts appear to be rather plain grayish. Also, the visible pattern of the underparts seems distinctly canus-like with a grayish wash ending abruptly just posterior to the legs leaving an almost unmarked, white crissum. Don't young LBBG's show much more patterned underparts with barring/spotting on the crissum?

Interesting one this, i'm certain they're juv LBBG's. I can't make out any plain grey greater coverts - they may be there - but wouldn't have thought CG's would show this feature so soon after fledging. Nor would juv LBBG's show any adult-type feathering either at this stage. Size wise they seem fine for Lessers, and the dark face on the left hand bird is quite distinctive. In my experience, juv CG's have extremely scalloped uppers - inviting confusion with juv Med Gulls. Thinking that i was losing my marbles, i copied the photo and e-mailed it to a very experienced and highly regarded birder who runs one of the Birdlines. I didn't make any suggestions, just - "what are the imm gulls?". He replied LBBGs!

They're not big enough.
