call of a female emu at the ZOOM Erlebniswelt Gelsenkirchen in Germany

Ему (лат. Dromaius novaehollandiae) друга је по величини савремена птица, једини живи представник рода Dromaius. Она је ендемска у Аустралији где је највећа домаћа птица. Распон емуа покрива већи део копнене Аустралије, док су подврсте Тасманије, острва Кенгур и острва Кинг нестале након европског насељавања Аустралије 1788.

Историја

Emus were first reported as having been seen by Europeans when explorers visited the western coast of Australia in 1696. This was during an expedition led by Dutch captain Willem de Vlamingh who was searching for survivors of a ship that had gone missing two years earlier.[6] The birds were known on the eastern coast before 1788, when the first Europeans settled there.[7] The birds were first mentioned under the name of the "New Holland cassowary" in Arthur Phillip's Voyage to Botany Bay, published in 1789.[8][9]

Монтирани ему скелет

The species was named by ornithologist John Latham in 1790 based on a specimen from the Sydney area of Australia, a country which was known as New Holland at the time.[3][10] He collaborated on Phillip's book and provided the first descriptions of, and names for, many Australian bird species; Dromaius comes from a Greek word meaning "racer" and novaehollandiae is the Latin term for New Holland, so the name can be rendered as "fast-footed New Hollander".[11] In his original 1816 description of the emu, the French ornithologist Louis Jean Pierre Vieillot used two generic names, first Dromiceius and later Dromaius.[12] It has been a point of contention ever since as to which name should be used; the latter is more correctly formed, but the convention in taxonomy is that the first name given to an organism stands, unless it is clearly a typographical error.[13] Most modern publications, including those of the Australian government,[5] use Dromaius, with Dromiceius mentioned as an alternative spelling.[5]

Систематика

The emu was long classified, with its closest relatives the cassowaries, in the family Casuariidae, part of the ratite order Struthioniformes.[14] An alternate classification was proposed in 2014 by Mitchell et al., based on analysis of mitochondrial DNA. This splits off the Casuariidae into their own order, the Casuariformes,[15] and includes only the cassowaries in the family Casuariidae, placing the emus in their own family, Dromaiidae. The cladogram shown below is from their study.[16]

Two different Dromaius species were present in Australia at the time of European settlement, and one additional species is known from fossil remains. The insular dwarf emus, D. n. baudinianus and D. n. minor, originally present on Kangaroo Island and King Island respectively, both became extinct shortly after the arrival of Europeans.[17][18] D. n. diemenensis, another insular dwarf emu from Tasmania, became extinct around 1865. The mainland subspecies, D. n. novaehollandiae, remains common. The population of these birds varies from decade to decade, largely being dependent on rainfall; in 2009, it was estimated that there were between 630,000 and 725,000 birds.[19] Emus were introduced to Maria Island[20] off Tasmania, and Kangaroo Island off the coast of South Australia, during the 20th century. The Maria Island population died out in the mid-1990s. The Kangaroo Island birds have successfully established a breeding population.[21]

In 1912, the Australian ornithologist Gregory M. Mathews recognised three living subspecies of emu,[22] D. n. novaehollandiae (Latham, 1790),[23] D. n. woodwardi Mathews, 1912[24] and D. n. rothschildi Mathews, 1912.[25] The Handbook of the Birds of the World, however, argues that the last two of these subspecies are invalid; natural variations in plumage colour and the nomadic nature of the species make it likely that there is a single race in mainland Australia.[26][27] Examination of the DNA of the King Island emu shows this bird to be closely related to the mainland emu and hence best treated as a subspecies.[18]

Опис

Јаје емуа (Dromaius novaehollandiae)

Ему је највиша птица у Аустралији која не лети. Може да нарасте чак до 2 метра. Врат и ноге су дуги, а крила кратка, само 20 центиметара дуга. Имају двоструко перје, а оба слоја су исте дужине. Након митарења су ове птице тамне, али како пигменти који дају смеђу боју бледе на сунцу, постају светлије. Младунци имају издужене смеђе, крем и црне шаре које им служе да се прикрију у грмљу и у трави.

Женка полаже 9−20 јаја у априлу, мају и јуну. Тек снесена јаја су тамнозелена. Међутим, током инкубације тамне и постану скоро црна. Мужјак гради гнездо, седи на јајима и подиже младунце.

Некада је постојало више врста емуа, али их је човек истребио.

Распрострањеност

Ему насељава Аустралију. Живе у пустињама, равницама и шумама.

Исхрана

Хране се опортунистички, биљкама и инсектима.

Често долазе у поља житарица и у изворе у пустињи, па их многи фармери сматрају штеточинама.
