When to expect American in Wyoming
American Kestrels 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, American 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 — 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.
