When to expect pygmy nuthatches in Washington

Pygmy Nuthatchs live in Washington all year. Mild, wet winters on the Puget Sound; cold winters in the east. That makes the cold months the time your yard matters most to them: their winter diet shifts toward pine seeds.

Marine west-coast climate west of the Cascades, semi-arid shrub-steppe to the east.

Nesting in Washington

Across Washington, 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.

Dry, sunny summers west of the Cascades; hot in the Columbia Basin.

  • 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.
