The superb fairy-wren (Malurus cyaneus), also known as the superb blue-wren or colloquially as the blue wren, is a passerine bird of the family Maluridae, common and familiar across southeastern Australia. The species is sedentary and territorial, also exhibiting a high degree of sexual dimorphism; the male in breeding plumage has a striking bright blue forehead, ear coverts, mantle, and tail, with a black mask and black or dark blue throat. Non-breeding males, females and juveniles are predominantly grey-brown in colour; this gave the early impression that males were polygamous, as all dull-coloured birds were taken for females. Six subspecies groups are recognized: three larger and darker forms from Tasmania, Flinders and King Island respectively, and three smaller and paler forms from mainland Australia and Kangaroo Island.
Like other fairy-wrens, the superb fairy-wren is notable for several peculiar behavioural characteristics; the birds are socially monogamous and sexually promiscuous, meaning that although they form pairs between one male and one female, each partner will mate with other individuals and even assist in raising the young from such pairings. Male wrens pluck yellow petals and display them to females as part of a courtship display.
The superb fairy-wren can be found in almost any area that has at least a little dense undergrowth for shelter, including grasslands with scattered shrubs, moderately thick forest, woodland, heaths, and domestic gardens. It has adapted well to the urban environment and is common in suburban Sydney, Canberra and Melbourne. The superb fairy-wren eats mostly insects and supplements its diet with seeds.
The superb fairy-wren is one of 12 species of the genus Malurus, commonly known as fairy-wrens, found in Australia and lowland New Guinea. Within the genus, the superb fairy-wren's closest relative is the splendid fairywren; these two "blue wrens" are also related to the purple-crowned fairywren of northwestern Australia.
