When to expect saw-whet owls in Utah

Northern Saw-whet Owls live in Utah all year. Cold winters with valley inversions; mountain birds descend to backyards. That makes the cold months the time your yard matters most to them.

Semi-arid to arid, with the Wasatch Range rising above the Great Basin and red-rock canyon country in the south.

Nesting in Utah

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

Hot, dry summers.

  • 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.
