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.

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:

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.
