DNR: Ospreys and Peregrine Falcons Recovering, Sightings Up in Buena Vista County

Surveys and monitoring by the Iowa Department of Natural Resources found that ospreys and peregrine falcons are recovering across the state, with more frequent sightings and nesting reports in Buena Vista County. The DNR released the findings on January 19, 2026, noting that long-term restoration and protection efforts have driven the positive trend.

Ospreys and peregrine falcons were nearly wiped out in the mid-20th century, largely because of widespread pesticide use that thinned eggshells and reduced reproductive success. Reintroduction and conservation measures begun in the late 1980s and 1990s, including nest box programs and targeted habitat protections, helped reestablish breeding populations. The DNR said current surveys and ongoing monitoring indicate the recovery is continuing, with more nesting activity reported than in past decades.

For Buena Vista County, the return of these raptors has visible local effects. Storm Lake and other county lakes and wetlands now see more osprey activity during migration and breeding seasons, and peregrine falcons have been observed using tall structures and bluffs as hunting and nesting sites. Increased sightings have drawn interest from birdwatchers and local outdoor recreationists, and the presence of top predators signals improving ecosystem health for fish and smaller bird species.

The DNR emphasized continued monitoring and habitat protections as keys to maintaining gains. Conservation work over the past three decades included careful placement of nest platforms, reduction of pesticide exposure, and public education about minimizing disturbance at nest sites. Those measures, combined with citizen reports and field surveys, helped the agency track nesting success and population trends.

Local policy implications center on land use and infrastructure decisions that could affect raptor habitat. County conservation boards, landowners, and developers will face choices about shoreline management, tower siting, and timing of construction to avoid breeding seasons. Continued coordination between the DNR and Buena Vista County officials can help integrate raptor protections into planning and permitting without unduly restricting local economic activity.

For residents, the recovery offers both quality-of-life and civic engagement opportunities. Increased osprey and peregrine falcon sightings provide a draw for nature-based recreation and small-scale wildlife tourism. Reporting nest locations and unusual bird behavior to the Iowa Department of Natural Resources supports monitoring and helps wildlife managers respond to threats such as injury or habitat loss.

The rebound of ospreys and peregrine falcons in Buena Vista County is tangible evidence that sustained conservation can restore species once driven to the brink. Maintaining that progress will require ongoing monitoring, sensible land-management choices, and public cooperation so future generations can watch these raptors patrol local skies.
