Pygmy Nuthatchs in California

Pygmy Nuthatchs live in California all year. Wet, mild winters are the green season — the busiest time at coastal feeders as sparrows and hummingbirds settle in. That makes the cold months the time your yard matters most to them: their winter diet shifts toward pine seeds.

Mediterranean along the coast and Central Valley, alpine in the Sierra Nevada, and desert in the southeast.

Across California, pygmy nuthatches typically nest from April–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 summers with little rain from May to October; water and summer-blooming natives matter more than extra seed.

• Have boxes cleaned and mounted before March — 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.
