The Superb Fairy Wren or Fairy Wren - Malurus cyaneus - has a different appearance depending on gender and breeding condition. Breeding males have pale blue on the crown, on the back and below the eyes; the throat and chest are a very deep blue which appears black under most lighting and merges into a horizontal black band across the lower chest. A black horizontal band through the eyes continues behind the head. Wings are brown, underside dusky white. The tail is dark, dull blue. Grows to 13 or 14 centimetres long.
Females are brown overall with reddish-brown bill, eyebrows and between eye and bill; tail brownish. Females in south-east South Australia have blue-tails. Non-breeding males are similar to females but with black bills and shorter, dark blue tails. Juveniles are coloured as females with whitish under parts.
There are six subspecies of the Superb Fairy-wren. Variations include size, plumage colour, tail and leg length. Tasmanian birds (cyaneus) are slightly larger, brighter and longer-tailed; cyanochlamys (photographed) is common in south-eastern Australia from Rockhampton to the Victorian Western District, extending inland onto the western slopes of the Great Divide. Other subspecies live in Tasmania, on Bass Strait islands, in south-east South Australia and Western Victoria.
Lives in dense undergrowth on heath, open forest, gardens, roadsides and inland watercourses.
