Steller's Jays in California

Steller's Jays 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 cached acorns and pine nuts.

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

Across California, Steller's jays typically nest from March–June. Nest site: bulky cup in conifers 10–30 ft up. Females lay 2–6 eggs, incubate for 16–18 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.

• Steller's Jays don't use nest boxes. Keep dense native shrubs and trees such as ponderosa pine, coast live oak, oregon white oak for nest sites.
• Delay heavy pruning of shrubs until after June.
