Trumpeter swan (Cygnus buccinator) 

The success of the Trumpeter Swan restoration is being monitored through reports of swan sightings.  Information obtained through these observations lets us know of survival of the individuals, reproduction and gives us knowledge of habitat utilization.

You can help by reporting all sightings of marked Trumpeter Swans that you see.  This can be done in several ways.  First, print out the Trumpeter swan observation form to record your sightings. (This form is also available here as an MS Word format.)  This will guide you in providing the types of information that we record in our data base.  Please record and provide as much information as asked for on the observation form as possible.

When making observations of swan markers carefully note the type (neck-collar, wing marker or leg band) and color of the marker, then precisely record the alphanumeric code on the marker (this is usually 3 digits something like Red J05 or Green 6F2).

You can then call our office at 641-357-3517 and report the swan(s) you've observed. Alternatively you can mail the completed form to:

Or finally, you can E-Mail the Iowa DNR by using this e-mail link, Report a Marked Swan.

All observations that include verifiable marker codes will receive a response with updated information on the bird.

Over 3,500 observations of Iowa released Trumpeter Swans have been reported to the Iowa DNR from as far away places as Manitoba and Texas.
