Legalities aside, why was this bird considered a possible Arctic Loon?  It 
looks like a Common Loon to me.

Nick's pictures at http://www.pbase.com/quetzal/loon11122009 show retention 
of white spotting on the back that does not match Pacific/Arctic at all, 
but does match Common.  There are a plethora of tiny white spots all over, 
and the largest spots are small white squares.  No photos are presented of 
the back of the neck nor a good profile, so that's hard to judge, but the 
one photo makes the lower mandible appear to have a strong upturn at the 
gonys like a Common, not flat like a Pacific/Arctic.  I've never seen a 
Pacific/Arctic Loon in this plumage, but it doesn't seem to be arranging 
itself with a very distinct dark/white line down the neck.  All loon 
species have vent straps.
