Description of the Bird
Four swans were observed, all in adult plumage. Three of the four were larger. All three had the V-forehead, sloping forehead. A very light rusty color on the neck. Their neck appeared to thicken as it reached the body.

Call: none

Similar Species Discussion
Ruled out Mute and Whooper Swan due to bill color and Tundra Swan because a Tundra swan was observed at the same time.
Previous Experience
I have observed Trumpeter Swan in WY and both species in CO during the winter.
