The Superb Fairy-wren (Malurus cyaneus) makes a high pitched trill when calling.
The brightly colured adult male has a rich blue and black plumage above and on the throat with a grey-white belly and black bill. Females and juveniles are mostly brown above with a dull red-orange area around the eyes and brown bill. Females have a pale greenish gloss on their brown tails.
It lives in open forests, swamps, coastal areas and gardens. Family groups can often be seen foraging on the ground.
The nest is a dome-shaped structure made from grasses and other fine material. It is usually placed in a low bush. The female incubates the eggs alone, but both sexes feed the young.
