Came across two swans I could only identify as tundra swans. White but with tannish necks and heads. They had some number tags on their necks. We approached them and they were alert but pretty calm then hissed and raised their wings when we got within about 6-8 feet. Since this is clearly out of their range are they probably domesticated? There was a house about 1/4 mile away but generally it was a pretty wild around. Between Boxley and Ponca.
