When to expect white-breasted nuthatches in Colorado
White-breasted Nuthatchs live in Colorado all year. Cold snaps alternate with sunny, dry thaws; heated baths are valuable because natural water freezes nightly. 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 in the east and the Rocky Mountains through the center, with most backyards between 5,000 and 7,000 ft.
Nesting in Colorado
Across Colorado, 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.
Warm, dry days and cool nights; afternoon storms are common in July and August.
- 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.
