When to expect white-breasted nuthatches in Idaho
White-breasted Nuthatchs live in Idaho all year. Cold winters with inversions in the valleys; mountain finches and Bohemian Waxwings move into towns. That makes the cold months the time your yard matters most to them: their winter diet shifts toward acorns, hickory nuts and seeds; sunflower, peanuts and suet at feeders.
Semi-arid sagebrush plains along the Snake River and forested mountains to the north and center.
Nesting in Idaho
Across Idaho, white-breasted nuthatches typically nest from April–June. Nest site: natural cavities in large trees; occasionally nest boxes. Females lay 5–9 eggs, incubate for 13–14 days, and young leave the nest after 18–26 days.
Hot, dry summers in the Snake River Plain and cool mountain summers.
- Have boxes cleaned and mounted before March — white-breasted nuthatches begin prospecting ahead of egg-laying.
- Use a 1 1/4 in round entrance on a 4 × 4 in floor, mounted 5–20 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.
