When to expect house wrens in Massachusetts
House Wrens are summer residents in Massachusetts, arriving shortly before nesting begins in May and leaving after the young are independent. Through the season they feed on beetles, caterpillars and crickets; spiders and flies.
Humid continental with maritime influence on Cape Cod and the islands.
Nesting in Massachusetts
Across Massachusetts, house wrens typically nest from May–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.
Warm summers; nesting peaks late May to July.
- Have boxes cleaned and mounted before April — 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.
