When to expect saw-whet owls in Oregon

Northern Saw-whet 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, saw-whet owls typically nest from March–June. Plan around that window: February for setup, June for clean-out.

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

  • Have boxes cleaned and mounted before February — saw-whet owls begin prospecting ahead of egg-laying.
  • Use a 2 1/2 in entrance on a 6 × 6 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 June.
