When to expect barn swallows in Arizona
Barn Swallows are summer residents in Arizona, arriving shortly before nesting begins in April and leaving after the young are independent. Through the season they feed on flies, beetles and moths.
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 swallows typically nest from April–July. Nest site: mud cup on beams and ledges under shelter. Females lay 3–7 eggs, incubate for 12–17 days, and young leave the nest after 15–27 days.
Summer highs above 110°F in Phoenix and Tucson make water the single strongest attractant; the July monsoon triggers a second breeding pulse.
- Barn Swallows 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 July.
