The emu (/ ˈ iː m juː /; Dromaius novaehollandiae) is a species of flightless bird endemic to Australia, where it is the tallest native bird. It is the only extant member of the genus Dromaius and the third-tallest living bird after its African ratite relatives, the common ostrich and Somali ostrich. The emu's native ranges cover most of the ...
They are distantly related to the African ostriches and Australia's emu (the largest and second-largest living ratites, respectively), with rheas placing just behind the emu in height and overall size. Most taxonomic authorities recognize two extant species: the greater or American rhea (Rhea americana), and the lesser or Darwin's rhea (Rhea ...

The following species and subspecies are recognized: Dromaius novaehollandiae, emu, remains common in most of the more lightly settled parts of mainland Australia.Overall population varies from decade to decade according to rainfall; as low as 200,000 and as high as 1,000,000, but a typical figure is about half a million individuals.
The genus was used by Linnaeus and other early taxonomists to include the emu, rhea, and cassowary, until they each were placed in their own genera. [1] The Somali ostrich (Struthio molybdophanes) has recently become recognized as a separate species by most authorities, while others are still reviewing the evidence. [6] [7]
The common ostrich is the largest and heaviest living bird. Males stand 2.1 to 2.75 m (6 ft 11 in to 9 ft 0 in) tall and weigh 100 to 130 kg (220 to 290 lb), whereas females are about 1.75 to 1.9 m (5 ft 9 in to 6 ft 3 in) tall and weigh 90 to 120 kg (200 to 260 lb). [20]

Commonly known as the Mount Lofty Ranges Southern Emu-wren (MLSREW [13]), it is an endangered species under both the EPBC Act (Cwth) and the National Parks and Wildlife Act 1972 (SA).
EMU was chosen (with WALLABY) as one of the two highest-ranked proposals for ASKAP from an initial field of 39 expressions of interest. [2] EMU is an international project, and the EMU team consists of over 400 astronomers in 21 countries. In addition to planning and conducting the radio survey itself, the EMU project also includes
