When to expect pygmy nuthatches in Idaho
Pygmy 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 pine seeds.
Semi-arid sagebrush plains along the Snake River and forested mountains to the north and center.
Nesting in Idaho
Across Idaho, pygmy nuthatches typically nest from May–June. Nest site: cavity in dead pine; nest boxes. Females lay 4–9 eggs, incubate for 14–16 days, and young leave the nest after 20–22 days.
Hot, dry summers in the Snake River Plain and cool mountain summers.
- Have boxes cleaned and mounted before April — pygmy nuthatches begin prospecting ahead of egg-laying.
- Use a 1 1/4 in entrance on a 4 × 4 in floor, mounted 8–20 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.
