When to expect house wrens in Maryland
House Wrens are summer residents in Maryland, 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 subtropical on the Chesapeake coastal plain, cooler in the Appalachian west.
Nesting in Maryland
Across Maryland, 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.
Hot, humid summers around the Chesapeake.
- 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.
