When to expect western screech-owls in Arizona

Western Screech-Owls 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.

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

Nesting in Arizona

Across Arizona, western screech-owls typically nest from February–June. Plan around that window: January for setup, June for clean-out.

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

Have boxes cleaned and mounted before January — western screech-owls begin prospecting ahead of egg-laying.
Use a 3 in entrance on a 8 × 8 in floor, mounted 10–30 ft.
Fit a pole baffle or hole guard; ventilation gaps and drainage holes are essential.
Clean out old nests after each brood and again after June.
