Yet another oddity: it stood out from the graellsii as being very long legged, large and bulky (like marinus) with a grey upper tone unlike either and with a stonking bill.

Just an extreme graellsii, pretty sure not, possible marinusxgraellsii, gut feeling....

maybe graellsii/michahellis??? looks like a hybrid of some sort.

Initiallu identified the 1st winter bird as a Caspian, at range, but when it moved a lot closer, when the pictures were taken, it seems to take on a different persona. I've seen several large male Casps before but this bird just didn't have the same headshape and bill structure to those birds. Still felt and ID the bird as a Caspian but with run of local 'mixed bloods' felt there may be another answer.

The near adult type bird showed extensive dark marks in the primaries and the tails still had retained dark marks, to extensive fr a 4th winter bird, bird aged as a 3rd winter.

The adult hybrid, could be a LBBGxHG though the bill is on the big side, an unknown parentage bird I think it will have to go down as, damn hybrids.

Just over another month of local gulling for the season left, then looking forward to the summer juveniles...

the 2cy (1st cycle) with large eye has little coverts replaced thus maybe from the northern belt of cach breeding distribution (germany to central europ. russia) but this is variable within populations. head striation may give a hint to some herring blood but is well within cach variation. jizz is another thing i can't tell accurately from this one pic alone but i can see where your feeling is coming.

edit: i see ruud sees it the same way...

as for the 3rd winter - yes, i didn't tell anything else: 3rd winter = 3rd cycle = 4cy in february

ageing caspians

i found it a bit difficult to age these:

http://lou.bertalan.de/gulls/pic/vh/up_0805.jpg

and some more... if i have the time to dig them out.

what do you think about the 2 linked?
on first view they seem obvious: 2nd cycle and 3rd cycle.

the presumed 2nd cycle (3rd winter, 4cy) would be quite retarded.

the presumed 3rd cycle 3rd (winter, 4cy) has dark marks on primaries down to probably p2-3 (p4 tip visible, a very solid mark), mirrors small etc.

Not at all Jan, always good to get further views.

Like a say when the bird was at distance it was fully Identified as a Casp with no hesitation it was only when it came closer and when I got the images that is seemed slightly out of character to the characteristc Casps that I tend to get locally. I've had large males before but they have tended to show the classic headshape and profile, this birds head with streaking and heavy looking bill made me second guess my original identification, first gut reaction is usually the right one.

Hi Steve,

Do you have any more images of this bird?

Cheers,

Andy.

Steve Arlow · Feb 28, 2011

Unfortunately no other images of this bird, I think I deleted all of the others as it was basically in the same position.

when i see these pics, i see only caspian gulls near it. is it dominating numbers? how are YLG and cachs distributed among the lakes, do they gather in more or less unispecific groups or randomly mixed?

Cristian Mihai · Mar 3, 2011

Hi Lou, I would say that during the winter (when the weather is really cold) we have on the lakes in Bucharest 70%- 80% cachinnnas and only 20% -30 % michahellis.

Cristian Mihai · Mar 3, 2011

On March 3rd I found again the Great Black-baked Gull.

is a pic you'd want to see in western europe

: cach - gbbg - mich in a row - and the combination is unusal anywhere i guess.

Cristian Mihai · Mar 4, 2011

Herastrau - March 7th. Two "old" friends - Jamie's Caspian and the Great Black-backed (still there after 6 days).

Hello!

A few Yellow-legged Gulls (I believe) from Cicily (Dec-Jan)

ekopa · Mar 7, 2011

And these
7526-27 Seems a bit odd, but still YLG, doesn't it?

ekopa · Mar 7, 2011

Again, the older one on 7537, 7540 outstands, yet a YLG?
