The northern house wren is a very small passerine in the wren family Troglodytidae. It is found in southern Canada, the USA and Mexico. It occurs in most suburban areas in its range. It formerly included many subspecies resident in South America and in the Caribbean that are now considered as separate species. 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.

A tiny, energetic wren that thrives around people, readily nesting in birdhouses, fence posts, and crevices. Males often build several 'dummy' stick nests to attract a mate and defend territory. Its scientific genus name, Troglodytes, means 'hole-dweller,' reflecting its cavity-nesting habits. Despite its size, it sings a remarkably loud, bubbly song.
