Albert's lyrebird (''Menura alberti'') is a timid, pheasant-sized songbird which is endemic to subtropical rainforests of Australia, in a small area on the state border between New South Wales and Queensland. The rarer of the two species of lyrebirds, Albert's lyrebird is named after Prince Albert, the prince consort of Queen Victoria, queen of the United Kingdom. It lacks the elegant lyre-shaped tail feathers of the superb lyrebird and is found in a much more restricted range. In the past, Albert's lyrebirds were shot to be eaten in pies, to supply tail-feathers to "globe-trotting curio-hunters" or by vandals.〔Department of the Environment (2014).

Accessed Thu, 27 Mar 2014〕 The total population of Albert's lyrebirds is estimated at only 3,500 breeding birds 〔Garnett, S.T. & G.M. Crowley (2000). The Action Plan for Australian Birds 2000. (). Canberra, ACT: Environment Australia and Birds Australia.

Birds Australia Report Series 9. Page(s) 65.〕 ==Description== Albert’s lyrebird is a ground-dwelling bird with the female reaching approximately 75 cm in length and males 90 cm. They have a wingspan of 76–79 cm and weigh about 930 grams. They are chestnut-brown in colour with a rufous undertail, rump and throat. The bill is black; the iris dark brown or black, and it has a broad, blue-grey ring around the eye. The legs and feet are brownish grey to dark grey or black.〔Department of the Environment (2014).

The male has a spectacular tail composed of: (1) a central pair of long ribbon-like dark-brown median plumes; (2) six pairs of long, filmy and luxuriant filamentary feathers, which are black-brown above and dark grey below; and (3) a long broad fully webbed outermost pair of lyrates, which are black-brown above and dark grey below.〔Department of the Environment (2014).

When walking, the male carries its tail in an upward-curving train.〔Higgins, P.J., J.M. Peter & W.K. Steele, eds. (2001). Handbook of Australian, New Zealand and Antarctic Birds. Volume 5: Tyrant-flycatchers to Chats. Melbourne, Victoria: Oxford University Press.〕 Juveniles are separable from adults at close range. They are similar to the adult female, but can be distinguished by: (1) the richer and more uniform rufous-brown colouring on the chin, throat and foreneck, and brighter red-brown wash on the forehead and forecrown; (2) the slightly paler upperbody; (3) the softer, downy texture of the rump, lower belly and vent feathers; and, most importantly, (4) the tail feathers (excluding the central pair of medians) are distinctly narrower, more tapered and pointed.〔Higgins, P.J., J.M.
