Pygmy Nuthatchs in Arizona

Pygmy Nuthatchs 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 pine 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, pygmy nuthatches typically nest from April–June. Nest site: cavity in dead pine; nest boxes. Females lay 4–9 eggs, incubate for 14–16 days, and young leave the nest after 20–22 days.

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 March — pygmy nuthatches begin prospecting ahead of egg-laying.
• Use a 1 1/4 in entrance on a 4 × 4 in floor, mounted 8–20 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 June.
