When to expect American in Maine
American Kestrels live in Maine all year. Long, snowy winters; boreal finches and Pine Grosbeaks irrupt south in poor cone years. That makes the cold months the time your yard matters most to them.
Humid continental with a long, rocky Atlantic coast and extensive northern spruce-fir forest.
Nesting in Maine
Across Maine, American typically nest from April–June. Plan around that window: March for setup, June for clean-out.
Cool, short summers; many songbirds do not begin nesting until late May.
- 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.
