A lyrebird is either of two species of ground-dwelling Australianbirds, that form the genus, Menura, and the familyMenuridae. They are most notable for their superb ability to mimic natural and artificial sounds from their environment. As well as their extraordinary mimicking ability, lyrebirds are notable because of the striking beauty of the male bird's huge tail when it is fanned out in display; and also because of their courtship display. Lyrebirds have unique plumes of neutral coloured tailfeathers and are among Australia's best-known native birds.
