Thesouthern house wren (Troglodytes musculus) is a very smallpasserine bird in the wrenfamilyTroglodytidae. It is found from southern Mexico to southern Chile and southern Argentina. The nametroglodytes 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 beconspecific with thenorthern house wren (Troglodytes aedon).
The southern house wren wasformally described in 1823 by the German naturalistJohann Andreas Naumann under thebinomial nameTroglodytes musculus. He specified thetype locality as the state ofBahia in eastern Brazil.[1][2] The specific epithet isLatin meaning "little mouse".[3] The southern house wren was formerly considered to be part of the house wren complex that also included thenorthern house wren and six insular forms. The southern house wren was split from the complex based on the deepgenetic divergence,[4] differences in vocalizations[5][6] and differences in morphology.[7][8][9]
In Argentina, southern house wrens dispersed more frequently between-seasons than within a season, with females dispersing more often than males. Widowed and single males dispersed more frequently than paired males, whilst within-season divorce increased the breeding success of females but not males.[10]
