When to expect eastern screech-owls in Montana

Eastern Screech-Owls live in Montana all year. Very cold winters on the plains, with chinook winds bringing sudden thaws. That makes the cold months the time your yard matters most to them: their winter diet shifts toward mice and roosting birds.

Continental — Rocky Mountain forest in the west, semi-arid Great Plains in the east.

Nesting in Montana

Across Montana, eastern screech-owls typically nest from April–May. Nest site: tree cavity or nest box with wood-chip base. Females lay 2–6 eggs, incubate for 26–34 days, and young leave the nest after about 28 days.

Warm, dry summers and a short growing season.

  • Have boxes cleaned and mounted before March — eastern 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.
  • Clean out old nests after each brood and again after May.
