When to expect red-breasted nuthatches in Alberta
Red-breasted Nuthatchs live in Alberta all year. Cold winters broken by chinook thaws in the south. That makes the cold months the time your yard matters most to them: their winter diet shifts toward spruce, fir and pine seeds.
Continental — prairie in the southeast, aspen parkland in the center, boreal forest in the north and the Rockies in the west.
Nesting in Alberta
Across Alberta, 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.
Warm, sunny summers with long days.
- 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.
