When to expect house wrens in Washington

Nesting in Washington
Across Washington, 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.
Dry, sunny summers west of the Cascades; hot in the Columbia Basin.
- 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.
