When to expect white-breasted nuthatches in Wyoming
White-breasted Nuthatchs live in Wyoming all year. Cold, very windy winters. 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 high plains and basins with major mountain ranges; most towns lie above 5,000 ft.
Nesting in Wyoming
Across Wyoming, white-breasted nuthatches typically nest from May–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.
Short, warm summers with cool nights.
- Have boxes cleaned and mounted before April — 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.
