Here are some photos taken by Phil Douglass on 1 Mar 2005 at the Harold Crane WMA near Odgen.

Flock of Tundra Swans with one suspicious swan second to the bottom
  

Enlargement of bottom two swans: 
Could the top one be a Bewick's Swan (subspecies of the Tundras Swan)?
  

See photos sent in by Ted Steinke a week later from Salt Creek WMA
about 20 mile north of Harold Crane WMA.
