White-breasted Nuthatchs in New Hampshire

White-breasted Nuthatchs live in New Hampshire all year. Long, snowy winters; boreal species visit feeders in irruption years. 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.

Humid continental, with the White Mountains dividing the southern lowlands from northern forest.

Across New Hampshire, 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.

Mild summers; nesting starts late May.

• 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.
