When to expect house wrens in Nova Scotia
House Wrens are summer residents in Nova Scotia, arriving shortly before nesting begins in June and leaving after the young are independent. Uncommon breeder. Through the season they feed on beetles, caterpillars and crickets; spiders and flies.
Maritime — cool summers, snowy but ocean-moderated winters, fog and wind along the coast.
Nesting in Nova Scotia
Across Nova Scotia, 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 summers delay nesting compared with inland regions at similar latitude.
- 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.
