Pine Siskins in California

Pine Siskins 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 spruce, birch and alder seed.

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

Across California, pine siskins typically nest from March–June. Nest site: shallow cup far out on a conifer branch. Females lay 3–5 eggs, incubate for 13 days, and young leave the nest after 14–15 days.

Dry summers with little rain from May to October; water and summer-blooming natives matter more than extra seed.

• Pine Siskins don't use nest boxes. Keep dense native shrubs and trees such as ponderosa pine, rabbitbrush, palo verde for nest sites.
• Delay heavy pruning of shrubs until after June.
