both look like cachinnans. those longitudinal dark marked scapulars are not uncommon for caspian gulls, this ind. (2nd bird) being fairly advanced in moult (many replaced coverts).

well, you don't get these beasts in england (i'm still talking about no. 1) but this underwing is unique: http://gull-research.org/ichthyaetus/pallas3cy.html
voila, danube delta, flying overhead in may 2012, a 2nd cycle ichtyaetus.

If that's a YLG, then I'm overlooking some of them in the Dartford area. Is it a 3cy Herring Gull??
Cheers, Andy.

looks a lot like a 2nd cycle herring gull. one of those long winged north-eastern types probably. note 3rd gen. scaps and some 3rd gen. tertials - is this normally found in argentatus at this time of year?
can't turn it into a YLG though...congratulations, cristian, one more argentatus this winter, they sum up now to at ~ 4-5 obs.

I didn't manage to take shots with this bird in flight, but I would say that the wings were rather short and the terminal band of the tail was rather broad.

if you saw the tail like you describe it, there should be no doubt. but even without that i guess we can see enough to say it's a herring gull. :t:

2nd cycle YLG for me, pete. they are scarce up there, aren't they?

Completely agree.
Some can look a little like Graellsii LBBG but this is a YLG.
Cheers, Andy.
Hi lou and Andy, many thanks for your replies. I thought it was a YLG but with so many hybrids seemingly on the increase up here, I was a bit reticent to put a name to it. YLG`s are scarce up here, in fact this is the first I`ve seen on my local beach area this Winter( it was there again this morning).There are a few up river at Richmond Bank/ Arpley Tip in Cheshire, but the picture there is becoming cloudy too, with several hybrids turning up( including the recent colour-ringed Great Black-backed x Yellow-legged individual.)
cheers, Pete.

hi tsingy,
want to come back on these valuable pics (and difficult IDs for that matter
)
1. looks very good for adult heuglin's gull (larus fuscus heuglini): slate grey mantle, cachinnans like long bill and long legs.
2. pretty classic cachinnans (caspian gull) - long pale based bill, dark bill mark might suggest a younger adult, 4cy or 5cy.
3. pale mantled birds are caspians, but the dark one is from the fuscus-group. strangely it's jizz (head striation, shorter and yery yellow bill, apparently deep yellow legs) remind of a western fuscus (subsp. intermedius) but very late primary moult (p9 and p10 not fully grown) again suggest heuglini rather than graellsii/intermedius.
4. younger adult caspian (probably 4cy or 5cy), due to dark bill mark plus shortish ventral p10 tongue.
5. 2cy (1st winter) michahellis. extremely blunt tipped bill excludes cachinnans. armenicus usually has a paler underwing and paler head but i wonder if we can totally exclude this sp.
best wishes and good birding in 2013!

Hi folks, apologies for the rather poor pic, but any comments on the Gull in the centre of the pic.I thought it was a 1stw Yellow-legged?
thanks, Pete.View attachment 424750
