New data from the Iowa Department of Natural Resources shows the state's peregrine falcon population has continued to grow steadily in recent years, with 20 active nests recorded at the end of 2025. The raptors, once nearly wiped out in Iowa, were reintroduced through a restoration program starting in 1989 and are now found in urban areas, on bridges, and near energy plant towers.

Why it matters

The peregrine falcon's return to Iowa is seen as a conservation success story, with the birds playing a key role in the state's natural ecosystem as a top predator. The continued growth of the population also demonstrates the effectiveness of long-term wildlife restoration efforts.

The details

Iowa's peregrine falcon restoration program began in 1989 when the state released several dozen birds in Cedar Rapids and Des Moines. By 2003, a total of 169 falcons had been released statewide as part of a regional effort to reestablish the species across the Midwest. The latest data shows the population has continued to thrive, with 20 active nests recorded at the end of 2025.
