The Iceland gull is smaller than the closely related herring gull and is considered a medium-sized member of the gull family. They have a dove-like expression on their face, this is due to the smaller beak and rounded head. The Iceland gull has light coloured plumage all over, with accompanying white wingtips, just like the glaucous gull.
