When to expect Carolina wrens in Alabama
Carolina Wrens live in Alabama all year. Freezes are short and snow is rare; feeder traffic peaks as goldfinches, siskins and sparrows arrive from the north. That makes the cold months the time your yard matters most to them: their winter diet shifts toward suet, peanut pieces and mealworms at feeders.
Humid subtropical, with Gulf-influenced warmth in Mobile and Baldwin counties and cooler Appalachian foothills in the northeast.
Nesting in Alabama
Across Alabama, Carolina wrens typically nest from March–August. Nest site: domed cup in any cavity — hanging planters, sheds, mailboxes, brush. Females lay 3–7 eggs, incubate for 12–16 days, and young leave the nest after 10–16 days.
Long, humid summers with frequent thunderstorms — ventilated boxes and daily-refreshed water matter.
- Have boxes cleaned and mounted before February — Carolina wrens begin prospecting ahead of egg-laying.
- Use a 1 1/8–1 1/2 in entrance on a 4 × 4 in floor, mounted 5–10 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 August.
