House Sparrows in Arizona

House Sparrows 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 grain and feeder 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, house sparrows typically nest from March–August. Nest site: messy grass nest in any cavity, including nest boxes. Females lay 4–6 eggs, incubate for 10–14 days, and young leave the nest after 14 days.

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

• House Sparrows don't use nest boxes. Keep dense native shrubs and trees such as rabbitbrush, palo verde for nest sites.
• Delay heavy pruning of shrubs until after August.
