When to expect wood ducks in Iowa

Nesting in Iowa

Across Iowa, wood ducks typically nest from March–June. Plan around that window: February for setup, June for clean-out.

Have boxes cleaned and mounted before February — wood ducks begin prospecting ahead of egg-laying.
Use a 4 × 3 in oval entrance on a 10 × 18 in floor, mounted 6–20 ft.

Clean out old nests after each brood and again after June.
