When to expect house wrens in New Jersey

House Wrens are summer residents in New Jersey, 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 to subtropical, from the Highlands in the north to the Pine Barrens and Cape May.

Nesting in New Jersey

Across New Jersey, 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; Cape May is a world-class migration funnel.

  • 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.
