The '''Emu''' (pronunciation: {{IPAEng|ˈiːmjuː}}<ref>[http://dictionary.cambridge.org/define.asp?dict=CALD&key=25452&ph=on Cambridge Advanced Learner's Dictionary]</ref><ref>[http://www.bartleby.com/61/99/E0119900.html American Heritage Dictionary]</ref>), ''Dromaius novaehollandiae'', is the largest [[bird]] native to [[Australia]] and the only [[Extant taxon|extant]] member of the [[genus]] ''[[Dromaius]]''. It is also the second-largest extant bird in the world by height, after its [[ratite]] relative, the [[ostrich]]. The soft-feathered, brown, [[flightless bird]]s reach up to 2 m (6.5 ft) in height. The Emu is common over most of mainland Australia, although it avoids heavily populated areas, dense forest and arid areas. Emus can travel great distances at a fast, economical trot and, if necessary, can sprint at 50 [[Kilometres per hour|km/h]] (30 [[Miles per hour|mph]]) for some distance at a time.<ref name = "Davies">Davies, S. J. J. F. 1963. Emus. ''Australian Natural History'' 14:225–29</ref> They are opportunistically nomadic and may travel long distances to find food; they feed on a variety of plants and insects.
The Emu subspecies that previously inhabited [[Tasmania]] became extinct after the [[History of Australia (1788-1850)|European settlement of Australia]] in 1788; and the distribution of the mainland subspecies has been influenced by human activities. Once common on the east coast, Emu are now uncommon; by contrast, the development of agriculture and the provision of water for stock in the interior of the continent have increased the range of the Emu in arid regions. Emus are farmed for their meat, [[Emu oil|oil]] and leather.
==Taxonomy and distribution==
The emu was first described under the name of the New Holland Cassowary in [[Arthur Phillip|Arthur Phillip's]] ''Voyage to Botany Bay'', published in 1789.<ref name = "Gould">Gould, J. 1865. ''Handbook to the Birds of Australia'' Volume 2. Reprinted in 1972 by Landsdowne Press</ref> The species was named by ornithologist [[John Latham (ornithologist)|John Latham]], who collaborated on Phillip's book and provided the first descriptions of and names for many Australian bird species; its [[Binary name|name]] is Latin for "fast-footed [[New Holland (Australia)|New Hollander]]". The [[etymology]] of the common name Emu is uncertain, but is thought to have come from an Arabic word for large bird that was later used by Portuguese explorers to describe the related [[Cassowary]] in [[New Guinea]].<ref name = "AM" /> In Victoria, some terms for the emu were ''Barrimal'' in the [[Djadja wurrung]] language, ''myoure'' in [[Gunai]], and ''courn'' in [[Jardwadjali]].<ref name="Wesson 2001">{{cite book | author = Wesson, Sue C. | year = 2001 | title = Aboriginal flora and fauna names of Victoria: As extracted from early surveyors' reports | location = Melbourne | publisher = Victorian Aboriginal Corporation for Languages | url = http://www.vaclang.org.au/admin/file/content9/c7/ff.pdf | accessdate = 2006-11-11}}</ref>
In his original 1816 description of the emu, [[Louis Jean Pierre Vieillot|Vieillot]] used two [[genus|generic]] names; first ''Dromiceius'', then ''Dromaius'' a few pages later. It has been a point of contention ever since which is correct; the latter is more correctly formed, but the convention in [[Alpha taxonomy|taxonomy]] is that the first name given stands, unless it is clearly a [[typographical error]].<ref>http://elibrary.unm.edu/sora/Auk/v044n04/p0592-p0593.pdf</ref> Most modern publications, including those of the Australian government,<ref>[http://www.deh.gov.au/cgi-bin/abrs/fauna/details.pl?pstrVol=AVES;pstrTaxa=7787;pstrChecklistMode=2 Australian Faunal Directory - Redirect to new Environment Site<!-- Bot generated title -->]</ref> use ''Dromaius'', with ''Dromiceius'' mentioned as an alternative spelling.
===Classification===
[[Image:Emu02 - melbourne zoo.jpg|thumb|left|Emu eyes are golden brown to black. The naked skin on the neck is bluish-black]]
The Emu is classified in the family with their closest relatives the [[Cassowaries]] in the family [[Casuariidae]] in the [[ratite]] order [[Struthioniformes]]. However an alternate classification has been proposed splitting the Casuariidae into their own order Casuariformes.
Three different ''[[Dromaius]]'' species were common in Australia before European settlement, and one species is known from fossils. The small emus — ''[[Kangaroo Island Emu|Dromaius baudinianus]]'' and ''[[King Island Emu|D. ater]]'' — both became [[extinct]] shortly after; however, the Emu, ''D. novaehollandiae'', remains common. The population varies from decade to decade, largely dependent on rainfall; it is estimated that the Emu population is 625,000–725,000, with 100,000–200,000 in [[Western Australia]] and the remainder mostly in [[New South Wales]] and [[Queensland]].<ref name = "AM">Australian Museum. 2001. [http://www.amonline.net.au/birds/factsheets/emu.htm Emu ''Dromaius novaehollandiae'']</ref> ''D. novaehollandiae diemenensis'', a subspecies known as the [[Tasmanian Emu]], became extinct around 1865. Emus were introduced to [[Maria Island]] off Tasmania and [[Kangaroo Island]] near South Australia during the 20th century. The Kangaroo Island birds have established a breeding population there. The Maria Island population became extinct in the mid-1990s.
There are three extant [[subspecies]] in Australia:
* In the southeast, ''D. novaehollandiae novaehollandiae'', with its whitish ruff when breeding;
* In the north, ''D. novaehollandiae woodwardi'', slender and paler; and
* In the southwest, ''D. novaehollandiae rothschildi'', darker, with no ruff during breeding.
==Description==
[[Image:S6001444.JPG|thumb|Emus have only three toes in a [[Syndactyl#In birds|tridactyl]] arrangement; this adaptation for running is seen in other bird species, such as [[bustard]]s and [[quail]]s. The [[Ostrich]] has only two toes]]
Emus are large birds. The largest can reach up to two metres (6 ft 7 inches) in height (1–1.3 metres (3.2–4.3 ft) at the shoulder). Emus weigh between 30 and 55 kilograms (66–121 [[Pound (mass)|pounds]]).<ref>[http://animaldiversity.ummz.umich.edu/site/accounts/information/Dromaius_novaehollandiae.html ADW: Dromaius novaehollandiae: Information<!-- Bot generated title -->]</ref>.
They have small [[Vestigial structure|vestigial]] wings and a long neck and legs. Their ability to run at high speeds is due to their highly specialised pelvic limb musculature. Their feet have only three toes and a similarly reduced number of bones and associated foot muscles; they are the only birds with [[gastrocnemius muscle]]s in the back of the lower legs. The pelvic limb muscles of Emus have a similar contribution to total body mass as the flight muscles of flying birds.<ref>Patak, A. E. and Baldwin, J. 1998 Pelvic limb musculature in the emu Dromaius novaehollandiae (Aves : Struthioniformes: Dromaiidae): Adaptations to high-speed running. ''Journal of Morphology'' 238:23–37 PMID 9768501</ref>
[[Image:S6001445.JPG|thumb|left|Emu head.]]
Emus have brown to grey-brown plumage of shaggy appearance; the shafts and the tips of the [[feather]]s are black. Solar radiation is absorbed by the tips, and the loose-packed inner [[plumage]] insulates the skin. The resultant heat is prevented from flowing to the skin by the insulation provided by the coat,<ref>Maloney, S. K. and Dawson, T. J. 1995. The heat load from solar radiation on a large, diurnally active bird, the emu (Dromaius novaehollandiae). ''Journal of Thermal Biology'' 20:381–87</ref> allowing the bird to be active during the heat of the day. A unique feature of the Emu feather is its double rachis emerging from a single shaft. The sexes are similar in appearance.
On very hot days, Emus pant to [[Thermoregulation|maintain their body temperature]], their lungs work as [[evaporation|evaporative]] coolers and, unlike some other species, the resulting low levels of [[carbon dioxide]] in the blood do not appear to cause [[alkalosis]].<ref>Maloney, S.K. and Dawson, T.J. 1994. Thermoregulation in a large bird, the Emu (Dromaius novaehollandiae). ''Comparative Biochemistry and Physiology. B, Biochemical Systemic and Environmental Physiology.'' 164:464–72 </ref> For normal breathing in cooler weather, they have large, multifolded nasal passages. Cool air warms as it passes through into the lungs, extracting heat from the nasal region. On exhalation, the Emu's cold nasal [[turbinate]]s condense moisture back out of the air and absorb it for reuse.<ref>Maloney, S.K. and Dawson, T.J. 1998. Ventilatory accommodation of oxygen demand and respiratory water loss in a large bird, the emu (Dromaius novaehollandiae), and a re-examination of ventilatory allometry for birds. ''Physiological Zoology'' 71:712–19</ref>
Their calls consist of loud booming, drumming and grunting sounds that can be heard up to two kilometers away. The booming sound is created in an inflatable neck sac.<ref name= "AM" />
==Ecology and behaviour==
Emus live in most habitats across Australia, although they are most common in areas of [[sclerophyll]] forest and [[savanna]] woodland, and least common in populated and very arid areas. Emus are largely solitary, and while they can form enormous flocks, this is an atypical social behaviour that arises from the common need to move towards food sources. Emus have been shown to travel long distances to reach abundant feeding areas. In [[Western Australia]], Emu movements follow a distinct seasonal pattern — north in summer and south in winter. On the east coast their wanderings do not appear to follow a pattern.<ref name = "Congress" /> Emus are also able to swim when necessary.
===Diet===
Emus forage in a [[Day|diurnal]] pattern. They eat a variety of native and introduced plant species; the type of plants eaten depends on seasonal availability. They also eat insects, including [[grasshopper]]s and [[Cricket (insect)|cricket]]s, [[Coccinellidae|lady birds]], soldier and saltbush caterpillars, [[Bogong moth|Bogong]] and [[Heliothis|cotton-boll]] moth larvae and ants.<ref>Barker, R. D. and Vertjens, W. J. M. The Food of Australian Birds 1 Non-Passerines. CSIRO Australia ISBN 0-643-05007-8</ref> In Western Australia, food preferences have been observed in travelling Emus: they eat seeds from ''[[Acacia aneura]]'' until it rains, after which they eat fresh grass shoots and caterpillars; in winter they feed on the leaves and pods of ''[[Cassia]]''{{Verify source|date=December 2007}}<!-- might be genus Senna today, in any case the link is wrong -->; in spring, they feed on grasshoppers and the fruit of ''[[Santalum acuminatum]]'': a sort of [[quandong]].<ref name = "Davies" /><ref name="Powell">{{Cite book|title=Leaf and Branch|author=Robert Powell|publisher= Department of Conservation and Land Management |date=1990|page=197|quote=Quandong's fruits are an important food for the emu. ...major dispersers...}}</ref> Emus serve as an important agent for the dispersal of large viable seeds, which contributes to floral biodiversity.<ref>McGrath, R. J. and Bass, D. 1999. Seed dispersal by Emus on the New South Wales north-east coast. ''EMU'' 99: 248–52</ref><ref name="Powell"/>
===Breeding===
[[Image:Baby Emu.jpg|right|220px|thumb|left|Emu chicks have distinctive bilateral stripes that help to camouflage them]]
Emus form breeding pairs during the summer months of December and January, and may remain together for about five months. Mating occurs in the cooler months of May and June. During the breeding season, males experience hormonal changes, including an increase in [[luteinizing hormone]] and [[testosterone]] levels, and their [[testicles]] double in size.<ref>Malecki I. A. et al. 1998. Endocrine and testicular changes in a short-day seasonally breeding bird, the emu (Dromaius novaehollandiae), in southwestern Australia. ''Animal Reproduction Sciences'' 53:143–55 PMID 9835373</ref> Males lose their appetite and construct a rough nest in a semi-sheltered hollow on the ground from bark, grass, sticks and leaves. The pair mates every day or two, and every second or third day the female lays an average of 11 (and as many as 20) very large, thick-shelled, dark-green eggs. The eggs are on average 134 x 89 millimeters (5.3 x 3.5 inches) and weigh between 700 and 900 [[gram]]s (1.5–2 pounds),<ref name= "Reader's Digest">Reader's Digest Complete Book of Australian Birds. 1976. Reader's Digest Services ISBN 0-909486-63-8</ref> which is roughly equivalent to 10–12 chicken eggs in volume and weight. The first verified occurrence of genetically identical avian twins was demonstrated in the Emu.<ref>Bassett, S. M. et al. 1999. Genetically identical avian twins. ''Journal of Zoology'' 247: 475–78</ref>
The male becomes broody after his mate starts laying, and begins to incubate the eggs before the laying period is complete. From this time on, he does not eat, drink or defecate, and stands only to turn the eggs, which he does about 10 times a day. Over eight weeks of incubation, he will lose a third of his weight and will survive only on stored body-fat and on any morning dew that he can reach from the nest. As with many other Australian birds, such as the [[Superb Fairy-wren]], infidelity is the norm for Emus, despite the initial pair-bond: once the male starts brooding, the female mates with other males and may lay in multiple clutches; thus, as many as half the chicks in a brood may be fathered by others, or by neither parent as Emus also exhibit [[Brood parasite|brood parasitism]].<ref>Taylor, E. L. et al. 2000. Genetic evidence for mixed parentage in nests of the emu (Dromaius novaehollandiae). ''Behavioural Ecology and Sociobiology'' 47:359–64</ref> Some females stay and defend the nest until the chicks start hatching, but most leave the nesting area completely to nest again; in a good season, a female Emu may nest three times.<ref name = "Congress">Davies, S. J. J. F. 1976. The natural history of the Emu in comparison with that of other ratites. In ''Proceedings of the 16th international ornithological congress'', H.J. Firth and J. H. Calaby eds. Australian Academy of Science, p. 109–20 ISBN 0-85847-038-1 </ref>
Incubation takes 56 days, and the male stops incubating the eggs shortly before they hatch.<ref name = "Congress" /> Newly hatched chicks are active and can leave the nest within a few days. They stand about 25 centimetres tall and have distinctive brown and cream stripes for camouflage, which fade after three months or so. The male stays with the growing chicks for up to 18 months, defending them and teaching them how to find food.<ref name="Reader's Digest" /> Chicks grow very quickly and are full-grown in 12–14 months; they may remain with their family group for another six months or so before they split up to breed in their second season. In the wild, Emus live between 10 to 20 years;<ref>Parks Victoria. [http://www.parkweb.vic.gov.au/education/factfiles/16.htm Emu]</ref> captive birds can live longer than those in the wild.
== Relationship with humans ==
=== Conservation status===
Emus were used as a source of food by [[indigenous Australians]] and early European settlers. Aborigines used a variety of techniques to catch the bird, including spearing them while they drank at waterholes, poisoning waterholes, catching Emus in nets, and attracting Emus by imitating their calls or with a ball of feathers and rags dangled from a tree.<ref name = "Reader's Digest" /> Europeans killed Emus to provide food and to remove them if they interfered with farming or invaded settlements in search of water during drought. An extreme example of this was the [[Emu War]] in Western Australia in 1932, when Emus that flocked to [[Campion, Western Australia|Campion]] during a hot summer scared the town’s inhabitants and an unsuccessful attempt to drive them off was mounted. In [[John Gould|John Gould's]] ''Handbook to the Birds of Australia'', first published in 1865, he laments the loss of the Emu from Tasmania, where it had become rare and has since become extinct; he notes that Emus were no longer common in the vicinity of Sydney and proposes that the species be given protected status.<ref name = "Gould" /> Wild Emus are formally protected in Australia under the ''[[Environment Protection and Biodiversity Conservation Act 1999]]''.
Although the population of Emus on mainland Australia is thought to be higher now than before European settlement,<ref name = "AM" /> some wild populations are at risk of local extinction due to small population size. Threats to small populations include the clearance and fragmentation of areas of habitat; deliberate slaughter; collisions with vehicles; and predation of the young and eggs by foxes, feral and domestic dogs, and feral pigs. The isolated Emu population of the New South Wales North Coast Bioregion and [[Port Stephens Council|Port Stephens]] is listed as endangered by the New South Wales Government.<ref>Department of Environment and Conservation (NSW) [http://threatenedspecies.environment.nsw.gov.au/tsprofile/profile.aspx?id=10250 Emu population in the NSW North Coast Bioregion and Port Stephens LGA - profile]</ref>
===Economic value===
The Emu was an important source of meat to the Aborigines in the areas to which it was endemic. Emu fat was used as bush medicine, and was rubbed on the skin. It also served as a valuable lubricant. It was mixed with [[ochre pits|ochre]] to make the traditional paint for ceremonial body adornment, as well as to oil wooden tools and utensils such as the [[Coolamon (vessel)|coolamon]].<ref>[http://www.samemory.sa.gov.au/site/page.cfm?u=750&c=2147 South Australia Memory]</ref>
An example of how the Emu was cooked comes from the [[Arrernte]] of [[Central Australia]] who call it ''Kere ankerre'':
{{blockquote|Emus are around all the time, in green times and dry times. You pluck the feathers out first, then pull out the crop from the stomach, and put in the feathers you've pulled out, and then singe it on the fire. You wrap the milk guts that you've pulled out into something [such as] gum leaves and cook them. When you've got the fat off, you cut the meat up and cook it on fire made from river [[red gum]] wood.<ref> Turner, Margaret-Mary, ''Arrernte Foods: Foods from Central Australia'', IAD Press, Alice Springs, 1994, ISBN 0-949659-76-2 p47</ref>}}
[[Image:Feeding farmed Emu.jpg|220px|right|thumb|Farmed Emu at Virginia's Emu Marketing Cooperative near [[Warrenton, Virginia]], US.]]
Commercial Emu farming started in [[Western Australia]] in 1987 and the first slaughtering occurred in 1990.<ref>O'Malley, P. 1997. [http://www.rirdc.gov.au/pub/handbook/emu.html Emu Farming] in ''The New Rural Industries''. Rural Industries Research & Development Corporation</ref> In Australia, the commercial industry is based on stock bred in captivity and all states except Tasmania have licensing requirements to protect wild Emus. Outside Australia, Emus are farmed on a large scale in [[North America]], with about 1 million birds in the US,<ref name = "USDA">USDA. [http://www.fsis.usda.gov/Fact_Sheets/Ratites_Emu_Ostrich_Rhea/index.asp Ratites (Emu, Ostrich, and Rhea)]</ref> [[Peru]] and [[People's Republic of China|China]], and to a lesser extent in some other countries. Emus breed well in captivity, and are kept in large open pens to avoid leg and digestive problems that arise with inactivity. They are typically fed on grain supplemented by grazing, and are slaughtered at 50–70 weeks of age. They eat two times a day and prefer 5 pounds of leaves each meal.
Emus are farmed primarily for their meat, leather and [[emu oil|oil]]. Emu meat is a low-fat, low-cholesterol meat (85 mg/100 g); despite being avian, it is considered a [[red meat]] because of its red colour and pH value.<ref>USDA. 2005. USDA National Nutrient Database for Standard Reference, Release 18 [http://www.nal.usda.gov/fnic/foodcomp/cgi-bin/list_nut_edit.pl?NDB_NO=05626&FDGP_CD=0500&FOOD_NAME=Emu%252c%2520full%2520rump%252c%2520raw&SCI_NAME=Dromaius%2520novaehollandiae&MSRE_NO0=100grams&GRAMS_100=1.00&1=1.00&NUMBER_OF_CHECKBOXES=1 Emu, full rump, raw]</ref><ref name = "USDA" /> The best cuts come from the thigh and the larger muscles of the drum or lower leg. Emu fat is rendered to produce oil for cosmetics, dietary supplements and therapeutic products. There is some evidence that the oil has anti-inflammatory properties;<ref>Yoganathan, S. et al. 2003. Antagonism of croton oil inflammation by topical emu oil in CD-1 mice. ''Lipids'' 38:603–07. PMID 12934669</ref> however, the US [[Food and Drug Administration]] regards pure emu oil product as an unapproved drug. Emu leather has a distinctive patterned surface, due to a raised area around the feather follicles in the skin; the leather is used in such small items as wallets and shoes, often in combination with other leathers. The feathers and eggs are used in decorative arts and crafts.

[[Image:Emu stamp.png|thumb|180px|New South Wales 100th Anniversary stamp]]
The Emu has a prominent place in [[Australian Aboriginal mythology]], including a [[creation myth]] of the [[Gamilaraay language|Yuwaalaraay]] and other groups in NSW who say that the sun was made by throwing an Emu's egg into the sky; the bird features in numerous [[Etiology|aetiological]] stories told across a number of Aboriginal groups.<ref>Dixon, R. B. 1916. ''Oceanic Mythology'' [http://www.sacred-texts.com/pac/om/ Part V.

The Emu is popularly but unofficially considered as a faunal emblem—the [[List of national birds|national bird]] of Australia.<ref>Department of Foreign Affairs and Trade. [http://www.dfat.gov.au/facts/coat_of_arms.html Australia's Coat of Arms]</ref> It appears as a shield bearer on the [[Coat of Arms of Australia]] with the [[Red Kangaroo]] and as a part of the Arms also appears on the Australian [[Coins of the Australian dollar|50 cent coin]]. It has featured on numerous Australian [[postage stamp]]s, including a [[federation of Australia|pre-federation]] New South Wales 100th Anniversary issue from 1888, which featured a 2 [[penny|pence]] blue Emu stamp, a 36 cent stamp released in 1986, and a $1.35 stamp released in 1994. The hats of the [[Australian Light Horse]] were famously decorated with an Emu feather plume.
There are around 600 [[Gazetteer of Australia|gazetted]] places named after the Emu in Australia, including mountains, lakes, creeks and towns.<ref>Geoscience Australia. 2004. [http://www.ga.gov.au/bin/gazm01?placename=emu&placetype=0&state=0 Gazetteer of Australia]</ref> During the 19th and 20th centuries, many Australian companies and household products were named after the bird; for example, in Western Australia, Emu branded beer has been produced since the early 20th century. The [[Swan Brewery]] continues to produce a range of [[Emu (beer)|Emu]] branded beers. ''[[Emu (journal)|Emu - Austral Ornithology]]'' is the quarterly peer-reviewed publication of the [[Royal Australasian Ornithologists Union]], also known as Birds Australia.
