Polk County Conservation

Wood ducks are one of many waterfowl that call Polk County home during the warm season. They are cavity nesters that seek out habitats along bodies of waters. Polk County Conservation’s manmade nest boxes help to give these birds places to call home among Polk County wetlands and other bodies of water. According to the Iowa DNR, wood ducks tend to begin to migrate to Iowa in March and leave in September with nesting taking place April through July. Wood duck nest box monitors are asked to annually visit their designated nest box(es) to empty and clean them out and refill them with wood shavings between January 1 and February 28th.
