Arctic Loon?

This is a picture of a loon that I took in Grantley Harbor in Teller. The bird is not commonly seen in the Teller area. Kendra Lee

LEO says:

This species of loon photographed by Kendra looks similar to the Pacific Loon (Gavia pacifica) because of the bird's white markings and the number of stripes on the wing. Found along the Western Coast of the United States during the fall and winter, and in Canada and Alaska, where they migrate for the breeding months. Unlike the Arctic Loon (Gavia arctica) a medium loon with straight, stout bill, white-spotted black back, white flanks visible above water while swimming. Head and nape are gray. Neck has bold black and white stripes on sides and green or purple throat bar that may be difficult to see. Feeds on fish, mollusks, and crustaceans. The range is from Alaska to Siberia. Breeds in Russia, Scandinavia, Alaska, and Canada. (Source: whatbird.com - Arctic & Pacific Loons)

Beth Paluso writes, Pacific and Arctic Loons are very tricky to tell apart, and I can’t tell much with the angle of that photo—the field marks include profile of head, color of the nape of the neck, bill size, all of which are difficult to see in this photo. According to the Birds of North America online, one of the few places where Arctic Loons nest in Alaska is on the Seward Peninsula, so it very well could be one. Were there other photos? Sorry, I’m not more help with this one! It’s a beautiful loon, whichever one it is.
