Rear  head and crown shape are somewhat blocky, suggestive of Trumpeter, 
feather  edge along the gape seems somewhat in between, certainly not a 
classic  
Trumpeter shape. Bill also seems short in the photos. This bird, on  January 
2nd, suggested a hybrid Trumpling, as Paul  says


Dave, Paul, etc.
 I would concur with "Trumpling" at least. It doesn't apper to have  
characteristics of pure Trumpeter. I looked very hard at all my photos again  last 
night, and the most telling thing I could see was the bill-length is almost  too 
perfect for Tundra Swan. It is not nearly long enough for Trumpeter. I got  
many good shots of the birds head in profile, facing both right and left. All of 
 my references show the bill length for Trumpeter being longer than the 
length of  the "chin" from where it meets the base of the bill to the neck, while 
in Tundra  Swan the bill should about equal the length of the "chin" space.  
Also, the  birds neck is rather short(ish) and thicker than I would expect in a 
pure  Trumpeter. Feather edge along the gape, as Dave notes, seemed somewhat 
"in  between" and seemed to change from one photo to the next in some of my 
shots,  but didn't seem nearly straight enough to rule out "trumpling".
 
My photos were shot from perhaps 75-100 yards distance.
