Dear colleagues,
I would appreciate your comments about to these Gull,
Picture taking on 22th May 2012 on dump in Minsk (Belarus).
1-4 - adult L.f.fuscus?
5 - adult graellsii?
6-7 - 4cv L.f. graellsii?
Thanks a lot,
dmitry

hi,

both look like intermedius or even graellsii to me. hard to exclude heuglini but on structure, pale iris, vivid bare colours (adult) i'd say it is one of the western taxons. fuscus fuscus is darker mantled.

Image 6 and 7:
For me heuglini. Note the bill pattern and the dark neck-drops.
