From 1989 – 1991, the Iowa Department of Natural Resources released 50 falcons at locations in Cedar Rapids, Des Moines and Muscatine through its Wildlife Diversity program. 

Young, 38 day-old falcon eyases that could feed themselves but not yet fly were placed in release structures or hack boxes.  They were fed so not to imprint upon people and released at 42 – 44 days old when their flight feathers were ready.

In 1993, the American Enterprise building at 601 Sixth Ave., in Des Moines, welcomed Iowa’s first pair of nesting falcons - each released in 1990 - a male from Cedar Rapids and female from Kansas City. Since then, this site has had three separate females and two males that produced 49 young. 

Falcon nesting in Iowa has grown incrementally from 1993 to 17 known nesting pairs around the state.  Last year, 15 nesting pairs fledged 34 young.

A 20th anniversary of falcon nesting in Iowa will be held in the outer courtyard area of American Enterprise building at 10 a.m., on Wednesday.  This is an opportunity for the public to learn about falcon recovery in Iowa while three young falcons are banded.
