Oak Titmice in California

Oak Titmouses 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 acorns and seeds.

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

Across California, oak titmice typically nest from February–May. Nest site: tree cavity or nest box. Females lay 3–9 eggs, incubate for 14–16 days, and young leave the nest after 16–21 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 January — oak titmice begin prospecting ahead of egg-laying.
• Use a 1 1/4 in entrance on a 4 × 4 in floor, mounted 5–15 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 May.
