Report Sightings of a Marked Swan

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.

Examples of swan collarsYou can help by reporting all sightings of marked Trumpeter Swans that you see. Print out the Trumpeter swan observation form to record your sightings. 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:
Iowa Department of Natural Resources
1203 North Shore Dr.
Clear Lake, Iowa  50428

Or Email: David.Hoffman@dnr.iowa.gov



All observations that include verifiable marker codes will receive a response with updated information on the bird. Over 4,000 observations of Iowa released Trumpeter Swans have been reported to the Iowa DNR from as far away places as Colorado, Virgnia, Texas, and 2 provinces of Canada.
