Taxonomy and Systematics
The classification of lyrebirds was the subject of much debate after the first specimens reached European scientists after 1798. They were thought to be Galliformes like the broadly similar looking partridge, junglefowl, and pheasants that Europeans were familiar with, and this was reflected in the early names the Superb Lyrebird had, including Native Pheasant. They were also called Peacock-wrens and Australian Birds-of-paradise. The idea that they were related to the pheasants was abandoned when the first chicks, which are altricial, were described. They were not placed with the passerines until a paper was published in 1840, 12 years after they were first placed in their own family, Menuridae. Within that family they are placed in a single genus, Menura.
It is generally accepted that the lyrebird family is most closely related to the scrub-birds (Atrichornithidae) and some authorities combine both in a single family, but evidence that they are also related to the bowerbirds remains controversial.
Lyrebirds are ancient Australian animals: the Australian Museum has fossils of lyrebirds dating back to about 15 million years ago. The prehistoric Menura tyawanoides has been described from Early Miocene fossils found at the famous Riversleigh site.
