Any oopinion about this white winged gull?

Dear friends:
This gull was sighted yesterday 18.1.2015 in NW top of Spain.
All dark tail, all dark bill, but I have no many experience with kumlien´s. It has not the best primary pattern for kum, perhaps, but I think this is a good candidate...
Any opinion about it?.
Thanks in advance
Antonio

The primaries are not very convincing indeed, but the tail pattern certainly is outside of the variation seen in glaucoides.
Therefore I would call this a Kumlien's Gull.
