The superb lyrebird (Menura novaehollandiae) is a pheasant-sized Australian songbird, measuring approximately 100 cm (39 in) long and weighing around 1 kg (2.2 lb), with brown upper body plumage, greyish-brown below, rounded wings and strong legs. Among all extant songbirds only the common and thick-billed ravens regularly outweigh it and only the much more slender black sicklebill can rival its length.
