When to expect American in Pennsylvania
American Kestrels live in Pennsylvania all year. Snow cover makes suet and heated water valuable; both chickadee species meet in a narrow hybrid zone across the south of the state. That makes the cold months the time your yard matters most to them.
Humid continental; cold, snowy winters in the north and mountains, milder in the southeast.
Nesting in Pennsylvania
Across Pennsylvania, American typically nest from March–June. Plan around that window: February for setup, June for clean-out.
Warm summers; bluebirds typically raise two broods.
- Have boxes cleaned and mounted before February — 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.
