Pacific Loon?... It's a Common Loon

Thanks to the response of several experienced birders it has been determined that the photos below depict a common loon.

A couple days ago i went out looking for the Pacific Loon that had been reported on Park Loop road in Bar Harbor. There were 6 loons present and i studied them all extensively. One loon stood out to me as beeing a little smaller more petite looking, however after a few minutes i concluded it was just a small, odd common loon. I did take a bunch of photos of this loon and now upon review, i'm considering that perhaps it is indeed a Pacific. Any thoughts on the ID of this bird would be appreciated.
