When to expect American in Montana

American Kestrels 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.

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

Nesting in Montana

Across Montana, American typically nest from April–June. Plan around that window: March for setup, June for clean-out.

Warm, dry summers and a short growing season.

  • Have boxes cleaned and mounted before March — American 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 June.
