hi pete,

looks like a 2nd cycle argenteus with all dark bill and tertials (and white head). can't think of any other sp. with such a covert pattern (both YLG and cach look totally different and would be more advanced). that's my two pence - but surely a striking bird! bit a of a melanin-monster ;)
 
Thanks Lou, I was wondering if it could be an Argentatus? the grey mantle feathering looked a tad dark for argenteus.Also maybe that might explain its white-headed look and dark tertials etc.In the UK we seem to get some very extreme looking Argie type Herring Gulls in the winter!
cheers, Pete.
 
yeah, jj, definitely looking good for an argie: structure (plump), leg colour, head striation, large apical spots (primary tips) and late primary moult - good find! B :)

check your mail, jj.
probably the first photographic documentation of heuglini from romania. but could be a hybrid. i'm a bit worried about the advanced primary moult.
 
ok, klaus malling says it's probably a graellsii. if it's 4cy this may account for the pale flesh coloured legs. but apical spots (white priamry tips) are large for a 4cy and pale tongue on p9 (underside), visible in the first pic here is suspect. adult heuglini excluded by moult score! but check these 4cy from november: http://gull-research.org/heuglini/04cynov.html

Still, there are two chances: hybrid and/or graellsii/heuglinii (3 chances), still we don't know why we cannot exclude a 4cy graellsii which would explain the the presence pale spots and leg color and markings bill. Maybe because it's a large white-headed gull??

hard to exclude a 4cy graellsii since an odd vagrant bird could well show the combination of large apical spots and flesh coloured legs (slight yellow tingue i see?). probably because it's a LWHG ;)

yes, cristian, at mamaia, today.
