Glaucous at Viana fishing harbour

Armando Caldas, as send me some nice photos, of two 1st winter Glaucous Gulls Larus hyperboreus  at Viana do Castelo fishing harbour.
With his courtesy I present the big boys that came from the north...

I wonder if this Great black backed Gull Larus marinus, is having second thoughs about being the "big" bird of the block....
