When to expect red-breasted nuthatches in Pennsylvania
Red-breasted Nuthatchs 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: their winter diet shifts toward spruce, fir and pine seeds.
Humid continental; cold, snowy winters in the north and mountains, milder in the southeast.
Nesting in Pennsylvania
Across Pennsylvania, red-breasted nuthatches typically nest from May–June. Nest site: excavated cavity in soft dead conifers or aspens; uses boxes. Females lay 5–8 eggs, incubate for 12–13 days, and young leave the nest after 18–21 days.
Warm summers; bluebirds typically raise two broods.
- Have boxes cleaned and mounted before April — red-breasted nuthatches begin prospecting ahead of egg-laying.
- Use a 1 1/4 in entrance on a 4 × 4 in floor, mounted 5–15 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.
