When to expect ospreys in Arizona

Ospreys are summer residents in Arizona, arriving shortly before nesting begins in February and leaving after the young are independent.

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, ospreys 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.

Ospreys don't use nest boxes. Keep dense native shrubs and trees such as black cherry, american elderberry, chokecherry for nest sites.
Delay heavy pruning of shrubs until after June.
