When to expect red-breasted nuthatches in Alaska
Red-breasted Nuthatchs live in Alaska all year. Interior winters reach −40°F with under four hours of daylight; resident chickadees and redpolls depend on high-fat food. That makes the cold months the time your yard matters most to them: their winter diet shifts toward spruce, fir and pine seeds.
Subarctic interior, temperate rainforest in the Southeast panhandle, and Arctic tundra on the North Slope.
Nesting in Alaska
Across Alaska, red-breasted nuthatches typically nest from 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.
A short, explosive summer with near-continuous daylight compresses nesting into a few weeks.
- Have boxes cleaned and mounted before May — 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.
