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,
