Oklahoma Breeding Bird Species Profile: House Wren





This upbeat and cheerful, bubbly sounding wren is common in dense, moist brushy patches, overgrown gardens, and thick hedgerows.  It has a thin, small eyebrow and is faintly barred with pale underparts.

Nesting in the northern segment of Oklahoma, it avoids drier uplands, choosing both natural and artificial nest cavities.  Dense, heavy woodlands are preferred for both living and breeding.

The most common wren has about the widest range of any song wren and besides nesting in the usual wren spots, has even been known to nest inside occupied houses.

Fond of spiders and insects, as well as insects more inclined to be on the wing, it will also consume snail shells for calcium and grit.

Males usually arrive upon breeding grounds about nine or ten days before females, and the immatures are shortly after the adult males.  Males will nest in the same territory or not far from it.  Females like to return to the previous nesting areas, so the male will have plenty of possible sites for her to choose from.  Almost half of the males will have a second mate within his territory, and about the same chance for him pairing with the same original individual the next season.

Musician wrens are very competitive for females while courting and will displace a rival about half the time.  He will even go so far as to destroy the eggs and nestlings of another pair.  Being known for puncturing the eggs of other species, the House Wren does it merely for survival of the species, and perhaps to increase food sources.

Nesting cavities will have a one inch diameter entrance with a twig bottom substrate.  Nest cups are made with feathers, grass, and other soft material.  The species is double-brooded.
