| Occurrence Remarks |
The documentation form by Ann M. Barker is the only one submitted and forms the basis of this record. Other observers include Don Moeller, Diann Huysinger, and Bernie Carpenter. | Elimination of similar species: Trumpeter Swan - immature had definite pink at base of bill, Trumpeter immature would show black at base. Both were seen straight on; white of forehead at base of bill appeared to come down between the eyes, unlike the Trumpeter, whose bill appears more straight across between the eyes. Black of bill did not include the eye as it would in Trumpeter. Mute Swan - birds in question had no knob at base of bill and necks were held straight rather than curved. Secondaries not raised. | The original documentation form event lasted from 10:00:00/10:15:00. |
