Trumpeter Swan
Cygnus buccinator

One of the few pictures I have of the Trumpeter in which the large yellow wing tags are not visible. The tag is there (no Photoshop editing has been applied here, I don't believe in doing that, what you see in my pictures is exactly what was in front of my lens), but is hidden under the birds feathers, and can only be seen if you look very close. To see the tags I am talking about click HERE.
