Some believe this is a Kumlien's Gull based on the patterns on the outer primaries together with the strong and heavy appearance, relatively strong bill and the extreme nicotine-brown shawl. However, others find that a heavily pigmented Iceland Gull due to the low quality pictures of especially the flying bird cannot be ruled out.
After seeing this Glaucous-winged Gull in the same harbour I felt some déjà vu because of the fine ‘cross hatching’ in the brown shawl. When the glaucescens and this white-winged gull was seen at close range the brownish breast, neck and head was all covered with fine distinct transverse bars, most prominent in the breast streaking.
