I've uploaded a few of many pictures of this loon with the pale yellow bill to my Flickr account with links below.
Again, it was seen at the end of the small rock jetty from the parking lot of Kelly's Brighton Marina on Hwy. 101 - very near to the rocks. Barely 50-75 feet away from me! As soon as I saw it I knew it was different from a Common Loon. I was able to see a breeding YB Loon in Nome this summer so this is my second this year!!
Big storms are coming tomorrow and the next few days, so I don't know how long it will stick around or where it might relocate to within the river/bay or elsewhere.
