I've made a little montage of some birds that were swimming together in the waters of Glacier Bay, Alaska on 30 June, just a week ago. They were quite far away and despite a zoom lens, the resolution is terrible. From another forum, I had two opinions, either Kittlitz's or Marbled Murrelet. In favour of Marbled, they are generally more common; however, from what I read, I am not sure that they are necessarily more common than Kittlitz's in Glacier Bay. I am leaning toward Marbled based on bill length, but I am on shaky ground! Thanks in advance.
