The striated fieldwren (Calamanthus fuliginosus) is a species of bird in the family Acanthizidae, endemic to Australia.

[3] It is a very familiar sound to hear in the months of winter and spring; however, there is a short period of time that the "sweet little strain" is not able to be heard.

The small olive-brown bird inhabits locations of dense heath, grassland, and salt marsh.

[8] Striated fieldwrens can be found alone, in pairs, or in family groups in the low bushes and shrubs of these areas.

[8] Their nests are hidden under dense brush and grass, in areas usually vulnerable to flooding or trampling livestock.

[8] Fieldwren's eat specific arthropods including beetles of the families Chrysomelidae, Curculionidae, Dytiscidae, and more.
