The small, superb fairy-wren is endemic to eastern Australia, ranging in habitat from south Queensland to South Australia’s Adelaide region, as well as throughout Tasmania. Males are easily distinguished from females by their distinctive colourings: mostly blue, with a black band across their back and head. This blue turns iridescent when the male is looking for a mate.
With its gleaming, velvety blue-and-black plumage, the male Superb Fairy-wren is easily distinguished. These ‘coloured’ males are often accompanied by a band of brown ‘jenny wrens’, often assumed to be a harem of females, but a proportion of them are males which have not yet attained their breeding plumage. The contents of these birds’ untidy nests — a clutch of three or four eggs — are not necessarily the progeny of the ‘coloured’ male, as there is much infidelity among female fairy-wrens, with many eggs resulting from extra-pair liaisons.
