Hi Dimitris et al.,
To my knowledge intermedius, graellsii and heuglini are very similar to each
other regarding upperpart coloration. As I said earlier: Whilst I agree that
the upperpart coloration is too dark for taimyrensis, it also doesn't look
good for fuscus. A fresh fuscus is almost black with almost no contrast to
the primary tips. A worn/bleached fuscus develops a brownish tinge to the
upperparts. This is in contrast to the cold dark grey upperparts of the
Broome bird.
The jizz fits best heuglini. To me the bird looks too heavy, too
long-legged, too short-winged, too big-headed and too large-billed for
fuscus.
I agree with Jeff Davies that the primaries (p1-6 versus p7-10) as well as
the secondaries are of two generations (initially I thought that all
primaries were old). This interrupted moult is according to Martin
Gottschling and Axel Mueller typical of three taxa: fuscus, heuglini and
taimyrensis (apparently not for graellsii and intermedius - I need to check
the literature).
So, taken everything together I would still say: L. h. heuglini, 3rd or 4th
winter.
What is Klaus Malling Olsen's opinion on this bird?
Cheers,
Nikolas

For me this bird is too dark to be Heuglins, with perhaps more fitting
candidates being fuscus or intermedius...
And then of course you have all the wonderful north hemisphere gull hybrid
combinations...
All the best,
D.
