The southern house wren is a very small passerine bird in the wren family Troglodytidae. It is found from southern Mexico to southern Chile and southern Argentina. The name troglodytes means "hole dweller", and is a reference to the bird's tendency to disappear into crevices when hunting insects or to seek shelter. It was formerly considered to be conspecific with the northern house wren.

The southern house wren is a tiny, energetic songbird that thrives in human-altered landscapes as well as natural habitats. Its genus name refers to "hole dweller," reflecting its habit of nesting and foraging in cavities and crevices. Males often build several starter nests to attract a mate, who then chooses one to line and use. Despite its size, it delivers a remarkably loud, bubbly song.
Temperament

short rapid wingbeats
Social Behavior
Typically seen as solitary individuals or in pairs during breeding. Males construct multiple stick nests within their territory; the female selects one to finish and use. A cavity nester, it readily adopts nest boxes and natural or man-made holes. Pairs can raise multiple broods in favorable conditions.

Song Description
A loud, bubbly series of trills and warbles that carries well for its size. Calls include harsh scolds and rapid chatters when agitated.
