Guide to Boreal Birds
This wren often nests in odd places such as mailboxes, flowerpots, and even the pockets of coats on clotheslines. When competing for a nest site, the House Wren may throw out the nest, eggs, and even the young of other hole-breeding birds. In the process this bird may kill its competitors, or if they are more powerful, it harasses them by filling the hole with its own nest material. If House Wrens return in spring to find an old nest still in place, they usually remove it stick by stick, then proceed to rebuild, often using the very material they've just discarded. Outside the breeding season, House Wrens are shy and much less in evidence than when they are singing during the breeding season.
