When to expect barn owls in Arizona
Barn 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, barn owls typically nest from December. Plan around that window: November for setup, December 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 November — barn owls begin prospecting ahead of egg-laying.
- Use a 6 in entrance on a 16 × 24 in floor, mounted 10–20 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 December.
