When to expect barn owls in Missouri
Barn Owls live in Missouri all year. Cold winters with variable snow; ice storms can shut down natural food for days. That makes the cold months the time your yard matters most to them.
Humid continental, from the Ozark Plateau in the south to prairie and river floodplains in the north.
Nesting in Missouri
Across Missouri, barn owls typically nest from January–December. Plan around that window: January for setup, December for clean-out.
Hot, humid summers.
- Have boxes cleaned and mounted before January — barn owls begin prospecting ahead of egg-laying.
- Use a 6 in entrance on a 16 × 24 in floor, mounted 10–20 ft.
- Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
- Clean out old nests after each brood and again after December.
