Nest
Domed, loosely built, with a side-entrance, composed of soft dry grass, lined with finer grass and a few feathers, placed near the ground in a low bush.
Eggs (Guide)
2 - 4; white, spotted with red-brown at the larger end; long-oval; about 15 x 11 mm. Incubation: about 13 days; by female.
Young
Altricial, nidicolous. Fledge in about 10 - 11 days.
Subspecies
Protein evidence indicates that closest allies are Red-backed Fairy-wren (Malurus melanocephalus) and White-shouldered Fairy-wren (Malurus alboscapulatus) and the three constitute the "bicoloured group". DNA evidence suggests that the two black-and-white island forms, i.e. nominate subspecies and edouardi, are not each other's closest relative. Further study is required. Possible genetic variation within subspecies leuconotus requires further investigation.
The following 3 subspecies are recognised:
leucopterus Dumont, 1824 - Dirk Hartog Island, WA.
leuconotus Gould, 1865 - Across mainland Australia from inland Qld, New South Wales and north-western Vic., to mid-coastal WA.
