The Superb Fairywren (Malurus cyaneus) is a passerine bird common and familiar across south-eastern Australia. The species is sedentary and territorial, also exhibiting a high degree of sexual dimorphism: the male in breeding plumage (shown here) has a striking bright blue forehead, ear coverts, mantle, and tail, with a black mask and black or dark blue throat, while non-breeding males, females and juveniles are predominantly grey-brown in colour.Photo: JJ Harrison
