When to expect barn owls in Oregon

Barn Owls live in Oregon all year. Mild, rainy winters in the Willamette Valley; cold, snowy winters east of the Cascades. That makes the cold months the time your yard matters most to them.

Marine west-coast climate west of the Cascades; high desert to the east.

Nesting in Oregon

Across Oregon, barn owls typically nest from January–December. Plan around that window: January for setup, December for clean-out.

Dry summers west of the Cascades; hot days in the high desert.

  • 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.
