Image of Common eider

Description:

I don't see eiders often and virtually never in eclipse plumage, so I am hoping some of you eider specialists can tell me what I have here. We have had a number of Kings and Commons that were well offshore but the males seemed identifiable. This group flew by rather close, but fast, but I got a few shots. Is the reddish brown bird with the white borders to the speculum area a Common and the others Kings, or are all these one species. I am, frankly, unsure and would appreciate some help. Thanks.
