Pine Siskins in Arizona

Pine Siskins live in Arizona all year. Low deserts stay mild and host many wintering sparrows and hummingbirds; the high country gets snow. That makes the cold months the time your yard matters most to them: their winter diet shifts toward spruce, birch and alder seed.

Hot Sonoran and Mojave deserts in the south and west, with pine-oak sky islands and the Colorado Plateau rising above 7,000 ft.

Across Arizona, 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.

Summer highs above 110°F in Phoenix and Tucson make water the single strongest attractant; the July monsoon triggers a second breeding pulse.

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