I was driving on a back-road I take every day to work. I looked out into the field and about 80 yards away or so, I saw 3 large, white birds with very long necks. They looked very slightly dirty. They were so unusual to me, I slowed down. My first thought was, "Is that a swan?" Then I thought maybe they were some kind of crane, but their legs were too short. Then I thought maybe they were a type of goose, but it's neck was too long, and they were bigger than Canadian Geese (which I've observed many times in that same field). They were in a field of new wheat sprouts, walking around and looked like they were eating the sprouts. There was standing water. Their bills were dark.
They were very calm and walking slowly. I should have taken a picture, but there was a bend in the road behind me, and nowhere to pull over.
They could have been Tundra Swans, but according to a pamphlet online, if the bills of the bird look > 2 Inches, it is likely a trumpeter swan. Their bills looked larger than 2 inches to me.
The bills were slightly flat at the end (less pointy than photos of Tundra Swan's bills I have seen so far).
