When to expect saw-whet owls in Wyoming

Northern Saw-whet Owls live in Wyoming all year. Cold, very windy winters. That makes the cold months the time your yard matters most to them.

Semi-arid high plains and basins with major mountain ranges; most towns lie above 5,000 ft.

Nesting in Wyoming

Across Wyoming, saw-whet owls typically nest from April–June. Plan around that window: March for setup, June for clean-out.

Short, warm summers with cool nights.

  • Have boxes cleaned and mounted before March — 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.
