When to expect saw-whet owls in Manitoba

Northern Saw-whet Owls live in Manitoba all year. Very cold winters to −30°F. That makes the cold months the time your yard matters most to them.

Continental, from prairie in the southwest to boreal forest and Hudson Bay tundra in the north.

Nesting in Manitoba

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

Warm summers with a short, intense nesting season.

  • 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.
