When to expect western screech-owls in Washington

Western Screech-Owls live in Washington all year. Mild, wet winters on the Puget Sound; cold winters in the east. That makes the cold months the time your yard matters most to them.

Marine west-coast climate west of the Cascades, semi-arid shrub-steppe to the east.

Nesting in Washington

Across Washington, western screech-owls typically nest from March–June. Plan around that window: February for setup, June for clean-out.

Dry, sunny summers west of the Cascades; hot in the Columbia Basin.

  • Have boxes cleaned and mounted before February — western screech-owls begin prospecting ahead of egg-laying.
  • Use a 3 in entrance on a 8 × 8 in floor, mounted 10–30 ft.
  • Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
