When to expect house wrens in Maine
House Wrens are summer residents in Maine, arriving shortly before nesting begins in June and leaving after the young are independent. Through the season they feed on beetles, caterpillars and crickets; spiders and flies.
Humid continental with a long, rocky Atlantic coast and extensive northern spruce-fir forest.
Nesting in Maine
Across Maine, house wrens typically nest from June–August. Nest site: almost any cavity — boxes, gourds, even boots and flowerpots; males build several stick-filled dummy nests. Females lay 3–10 eggs, incubate for 9–16 days, and young leave the nest after 15–17 days.
Cool, short summers; many songbirds do not begin nesting until late May.
- Have boxes cleaned and mounted before May — house wrens begin prospecting ahead of egg-laying.
- Use a 1 to 1 1/8 in round entrance on a 4 × 4 in floor, mounted 5–10 ft near shrubs.
- 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.
