Curve-billed Thrashers in Arizona

Curve-billed Thrashers 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 cactus fruit and seeds.

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, curve-billed thrashers typically nest from February–July. Nest site: twig cup in cholla or thorny shrubs. Females lay 2–4 eggs, incubate for 12–15 days, and young leave the nest after 14–18 days.

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

• Curve-billed Thrashers don't use nest boxes. Keep dense native shrubs and trees such as smooth sumac, black cherry, american elderberry for nest sites.
• Delay heavy pruning of shrubs until after July.
