Consider putting up a nest box to attract a breeding pair. Make sure you put it up well before breeding season. Attach a guard to keep predators from raiding eggs and young. Find out more about nest boxes on All About Birdhouses, where you'll find plans for building a nest box of the appropriate size for House Wren.
Wrens love brush piles for cover, protection, and a source of insects. If you need to prune trees or cut brush in your yard, consider heaping the cuttings into a pile as a safe place for birds to gather. More tips for attracting birds

Find This Bird
As with many birds, your ears can help lead you to House Wren sightings. Start in the right habitat: backyards, parks, or open woods, then listen. The song can be hard to learn at first, because the notes are nondescript and variable, and because there’s simply so much of it – so loud and insistent - that it’s hard to believe such a small bird is making it.
