The word "elk" originally referred to the European variety of the moose, ''Alces alces'', but was transferred to ''Cervus canadensis'' by North American colonists.
The name "wapiti" is derived from a Shawnee and Cree word meaning "white rump", after the distinctive light fur around the tail region which the animals may fluff-up or raise to signal their agitation or distress to one another, when fleeing perceived threats, or among males courting females and sparring for dominance. A similar trait is seen in other artiodactyl species, like the bighorn sheep, pronghorn and the white-tailed deer, to varying degrees.
Elk dwell in open forest and forest-edge habitats, grazing on grasses and sedges and browsing higher-growing plants, leaves, twigs and bark. Male elk have large, blood- and nerve-filled antlers, which they routinely shed each year as the weather warms. Males also engage in ritualized mating behaviors during the mating season, including posturing to attract females, antler-wrestling (sparring), and ''bugling'', a loud series of throaty whistles, bellows, screams, and other vocalizations that establish dominance over other males and aim to attract females.
Elk were long believed to belong to a subspecies of the European red deer (''Cervus elaphus''), but evidence from many mitochondrial DNA genetic studies, beginning in 1998, shows that the two are distinct species. The elk's wider rump-patch and paler-hued antlers are key morphological differences that distinguish ''C. canadensis'' from ''C. elaphus''. Although it is currently only native to North America, and Central, East and North Asia, elk once had a much wider distribution in the past; prehistoric populations were present across Eurasia and into Western Europe during the Late Pleistocene, surviving into the early Holocene in Southern Sweden and the Alps. The now-extinct North American Merriam's elk subspecies (''Cervus canadensis merriami'') once ranged south into Mexico. The wapiti has also successfully adapted to countries outside of its natural range where it has been introduced, including Argentina and New Zealand; the animal's adaptability in these areas may, in fact, be so successful as to threaten the sensitive endemic ecosystems and species it encounters.
As a member of the Artiodactyla order (and distant relative of the Bovidae), elk are susceptible to several infectious diseases which can be transmitted to or from domesticated livestock. Efforts to eliminate infectious diseases from elk populations, primarily by vaccination, have had mixed success. Some cultures revere the elk as having spiritual significance. Antlers and velvet are used in traditional medicines in parts of Asia; the production of ground antler and velvet supplements is also a thriving naturopathic industry in several countries, including the United States, China and Canada. The elk is hunted as a game species, and their meat is lean and higher in protein than beef or chicken.
==Naming and etymology== By the 17th century, ''Alces alces'' (moose, called "elk" in Europe) had long been extirpated from the British Isles, and the meaning of the word "elk" to English-speakers became rather vague, acquiring a meaning similar to "large deer".<ref name="Mallory-2006">{{Cite book |last1=Mallory |first1=J.P. |last2=Adams |first2=D.Q. |title=The Oxford Introduction to Proto-Indo-European and the Proto-Indo-European World |publisher=Oxford University Press |date=2006 |isbn= |location= |pages=133–134 }}</ref> The name ''wapiti'' is from the Shawnee and Cree word {{lang|sjw|waapiti}} (in Cree syllabics: {{lang|cr|ᐙᐱᑎ}} or {{lang|cr|ᐚᐱᑎ}}), meaning "white rump".<ref name="Wapiti">{{cite encyclopedia|title=Wapiti |encyclopedia=The Canadian Encyclopedia |publisher=Historica Canada |url=http://www.thecanadianencyclopedia.ca/en/article/wapiti/ |access-date=23 December 2016 }}</ref> There is a subspecies of wapiti in Mongolia called the Altai wapiti (''Cervus canadensis sibiricus''), also known as the Altai maral.<ref name="Wilson">{{MSW3 Artiodactyla | id = 14200352 | pages = 662–663}}</ref>
According to the ''Oxford English Dictionary'', the etymology of the word "elk" is "of obscure history". In Classical Antiquity, the European ''Alces alces'' was known as {{Langx|grc|ἄλκη|translit=álkē}} and {{Langx|la|alces}}, words probably borrowed from a Germanic language or another language of northern Europe. By the 8th century, during the Early Middle Ages, the moose was known as {{Langx|ang|elch, elh, eolh,}} derived from the Proto-Germanic: ''*elho-'', ''*elhon-'' and possibly connected with the {{Langx|non|elgr}}.<ref name="OED">{{cite web|last=|first=|year=1989|orig-date=1891|title=elk, ''n''. 1|url=http://www.oed.com/view/Entry/60507|url-access=subscription|url-status=live|archive-url=https://web.archive.org/web/20210309225208/https://www.oed.com/view/Entry/60507|archive-date=9 March 2021|access-date=January 15, 2021|work=Oxford English Dictionary|edition=2nd}}</ref> Later, the species became known in Middle English as ''elk'', ''elcke'', or ''elke'', appearing in the Latinized form ''alke'', with the spelling ''alce'' borrowed directly from {{Langx|la|alces|links=no}}.<ref name="OED" /><ref name="OED2">{{cite web|last=|first=|year=2012|title=alce, ''n.''|url=http://www.oed.com/view/Entry/4677|url-access=subscription|url-status=live|archive-url=https://web.archive.org/web/20210309225920/https://www.oed.com/view/Entry/4677|archive-date=9 March 2021|access-date=January 15, 2021|work=Oxford English Dictionary|edition=3rd}}</ref> Noting that ''elk'' "is not the normal phonetic representative" of the Old English ''elch'', the ''Oxford English Dictionary'' derives ''elk'' from {{Langx|gmh|elch}}, itself from {{Langx|goh|elaho}}.<ref name="Mallory-2006" /><ref name="OED" />
The American ''Cervus canadensis'' was recognized as a relative of the red deer (''Cervus elaphus'') of Europe, and so ''Cervus canadensis'' were referred to as "red deer". Richard Hakluyt refers to North America as a "lande ... full of many beastes, as redd dere"<ref>{{cite book |last=Hakluyt |first=Richard |date=1584 |title=History of the State of Maine.

Similarly, John Smith's 1616 ''A Description of New England'' referred to red deer. Sir William Talbot's 1672 English translation of John Lederer's Latin ''Discoveries'' likewise called the species "red deer", but noted in parentheses that they were "for their unusual largeness improperly termed Elks by ignorant people". Both Thomas Jefferson's 1785 ''Notes on the State of Virginia'' and David Bailie Warden's 1816 ''Statistical, Political, and Historical Account of the United States'' used "red deer" to refer to ''Cervus canadensis''.<ref name="OED3">{{cite web|last=|first=|year=2009|title=red deer, ''n''. 2|url=http://www.oed.com/view/Entry/160195|url-access=subscription|work=Oxford English Dictionary|edition=3rd}}</ref>

=== Subspecies === There are numerous subspecies of elk described, with six from North America and four from Asia, although some taxonomists consider them different ecotypes or races of the same species (adapted to local environments through minor changes in appearance and behavior). Populations vary in antler shape and size, body size, coloration and mating behavior. DNA investigations of the Eurasian subspecies revealed that phenotypic variation in antlers, mane and rump patch development are based on "climatic-related lifestyle factors".<ref name="groves">{{cite journal |last1=Groves |first1=Colin |title=The genus ''Cervus'' in eastern Eurasia |journal=European Journal of Wildlife Research |volume=52 |pages=14–22 |year=2005 |issue=1 |doi=10.1007/s10344-005-0011-5 |bibcode=2006EJWR...52...14G |s2cid=33193408 |url=http://archanth.anu.edu.au/sites/default/files/documents/groves_cervus2005.pdf |archive-url= https://web.archive.org/web/20140629063422/http://archanth.anu.edu.au/sites/default/files/documents/groves_cervus2005.pdf |archive-date=29 June 2014}}</ref> Of the six subspecies of elk known to have inhabited North America in historical times, four remain, including the Roosevelt (''C. canadensis roosevelti''), Tule (''C. c. nannodes''), Manitoban (''C. c. manitobensis'') and Rocky Mountain elk (''C. c. nelsoni'').<ref>{{cite web |title=American Elk (''Cervus elaphus'') |publisher=Natural Resources Conservation Service|access-date=2020-12-02 |url=https://www.nrcs.usda.gov/Internet/FSE_DOCUMENTS/nrcs143_010000.pdf|archive-date=16 January 2021|archive-url=https://web.archive.org/web/20210116133045/https://www.nrcs.usda.gov/Internet/FSE_DOCUMENTS/nrcs143_010000.pdf}}</ref> The eastern elk (''C. c. canadensis'') and Merriam's elk (''C. c. merriami'') subspecies have been extinct for at least a century.<ref name="Gerhart">{{cite web |last=Gerhart |first=Dorothy C. |title=Skull and Antlers of Extinct Eastern Elk Unearthed at Iroquois National Wildlife Refuge in Northwestern N.Y. |publisher=U.S. Fish and Wildlife Service |url=http://www.fws.gov/historicPreservation/archives/elkBones_012405.html |access-date=2010-12-04 |url-status=live |archive-date=16 July 2017 |archive-url=https://web.archive.org/web/20170716132759/https://www.fws.gov/historicPreservation/archives/elkBones_012405.html}}</ref><ref name="Allen">{{cite web|last=Allen |first=Craig |title=Elk Reintroductions |publisher=U.S. Geological Survey |url=https://biology.usgs.gov/s+t/SNT/noframe/sw159.htm |archive-url=https://web.archive.org/web/20060927142112/http://biology.usgs.gov/s%2Bt/SNT/noframe/sw159.htm |archive-date=2006-09-27 |access-date=2010-12-04 }}</ref>

Recent DNA analyses suggest that there are no more than three or four total subspecies of elk. All American forms, aside from possibly the Tule and the Roosevelt's elk, seem to belong to one subspecies—''Cervus c. canadensis''; even the Siberian elk (''C. c. sibiricus'') is, more or less, physically identical to the American forms, and thus may belong to this subspecies, too.<ref name="Mattioli, 2011" /> However, the Manchurian wapiti (''C. c. xanthopygus'') is clearly distinct from the Siberian forms, but not distinguishable from the Alashan wapiti. Still, due to the insufficient genetic material that rejects monophyly of ''C. canadensis'', some researchers consider it premature to include the Manchurian wapiti as a true subspecies of wapiti, and that it likely needs to be elevated to its own species, ''C. xanthopygus''.<ref>{{cite journal|author=Groves, C.|year=2006|title=The genus Cervus in eastern Eurasia|journal=European Journal of Wildlife Research|volume=52|issue=1 |pages=14–22|doi=10.1007/s10344-005-0011-5|bibcode=2006EJWR...52...14G }}</ref> The Chinese forms (the Sichuan deer, Kansu red deer, and Tibetan red deer) also belong to the wapiti, and were not distinguishable from each other by mitochondrial DNA studies.<ref name=Ludt/> These Chinese subspecies are sometimes treated as a distinct species, namely the Central Asian red deer (''Cervus hanglu''), which also includes the Kashmir stag.<ref name="Mattioli, 2011">{{cite book |last=Mattioli |first=Stefano |year=2011 |chapter=Family Cervidae (Deer) |pages=350–443 |editor1=Wilson, D.

Subspecies living in arid climates tend to have lighter colored coats than do those living in forests.<ref name="Pisarowicz">{{cite web|last=Pisarowicz |first=Jim |title=American Elk – ''Cervus elephus'' |publisher=National Park Service |url=http://www.nps.gov/wica/naturescience/elk-cervus-elephus.htm |access-date=5 January 2013 |archive-url=https://web.archive.org/web/20130115065744/http://www.nps.gov/wica/naturescience/elk-cervus-elephus.htm |archive-date=15 January 2013 }}</ref> Most have lighter yellow-brown to orange-brown coats in contrast to dark brown hair on the head, neck, and legs during the summer. Forest-adapted Manchurian and Alaskan wapitis have red or reddish-brown coats with less contrast between the body coat and the rest of the body during the summer months. Calves are born spotted, as is common with many deer species, and lose them by the end of summer. Adult Manchurian wapiti may retain a few orange spots on the back of their summer coats until they are older. This characteristic has also been observed in the forest-adapted European red deer.<ref name="Geist" />
==Behavior and ecology== thumb|Elk bulls sparring
Elk are among the most gregarious deer species.<ref name="Geist2" />{{rp|52}} During the summer group size can reach 400 individuals.<ref name="Adw" /> For most of the year, adult males and females are segregated into different herds. Female herds are larger while bulls form small groups and may even travel alone. Young bulls may associate with older bulls or female groups. Male and female herds come together during the mating season, which may begin in late August.<ref name="Geist2" />{{rp|75, 82}} Males try to intimidate rivals by vocalizing and displaying with their antlers.<ref name="Geist2" />{{rp|109}} If neither bull backs down, they engage in antler wrestling, sometimes sustaining serious injuries.<ref name="Washington" />
{{Listen|filename=American Elk Bugling.ogg|mini|title=An American elk bugling}}
Bulls have a loud, high-pitched, whistle-like vocalization known as ''bugling'', which advertise the male's fitness over great distances. Unusual for a vocalization produced by a large animal, buglings can reach a frequency of 4000 Hz. This is achieved by blowing air from the glottis through the nasal cavities. Elk can produce deeper pitched (150 Hz) sounds using the larynx.<ref>{{cite journal|vauthors=Reby D, Wyman MT, Frey R, Passilongo D, Gilbert J, Locatelli Y, Charlton BD|year=2016|title=Evidence of biphonation and source-filter interactions in the bugles of male North American wapiti (''Cervus canadensis'')|journal=Journal of Experimental Biology|volume=219|issue=8|pages=1224–36|doi=10.1242/jeb.131219|pmid=27103677|doi-access=free|bibcode=2016JExpB.219.1224R }}</ref> Cows produce an alarm bark to alert other members of the herd to danger, while calves will produce a high-pitched scream when attacked.<ref>{{cite book |author=Naughton, Donna |year=2014 |title=The Natural History of Canadian Mammals |publisher=University of Toronto Press|page=550|isbn=978-1-4426-4483-0}}</ref>

When a female wanders too far away from the harem's range, the male will rush ahead of her, block her path and aggressively rush her back to the harem. Herding behavior is accompanied by a stretched out and lowered neck and the antlers laid back. A bull may get violent and hit the cow with his antlers. During courtship, the bull is more peaceful and approaches her with his head and antlers raised. The male signals his intention to test the female for sexual receptivity by flicking his tongue. If not ready, a cow will lower her head and weave from side to side while opening and closing her mouth. The bull will stop in response in order not to scare her.<ref name="Geist2" />{{rp|100–101}} Otherwise, the bull will copiously lick the female and then mount her.<ref name="Geist2" />{{rp|115}}
Younger, less dominant bulls, known as "spike bulls", because their antlers have not yet forked, will harass unguarded cows. These bulls are impatient and will not perform any courtship rituals and will continue to pursue a female even when she signals him to stop. As such, they are less reproductively successful, and a cow may stay close to the big bull to avoid harassment. Dominant bulls are intolerant of spike bulls and will chase them away from their harems.<ref name="Geist2" />{{rp|100–105}}

Chronic wasting disease, transmitted by a misfolded protein known as a prion, affects the brain tissue in elk, and has been detected throughout their range in North America. First documented in the late 1960s in mule deer, the disease has affected elk on game farms and in the wild in a number of regions. Elk that have contracted the disease begin to show weight loss, changes in behavior, increased watering needs, excessive salivation and urinating and difficulty swallowing, and at an advanced stage, the disease leads to death. No risks to humans have been documented, nor has the disease been demonstrated to pose a threat to domesticated cattle.<ref>{{cite journal |vauthors=Belay ED, Maddox RA, Williams ES, Miller MW, Gambetti P, Schonberger LB |year=2004 |title=Chronic Wasting Disease and Potential Transmission to Humans|journal=Emerging Infectious Diseases|volume=10|issue=6|pages=977–984 |doi=10.3201/eid1006.031082 |pmc=3323184 |pmid=15207045}}</ref> In 2002, South Korea banned the importation of elk antler velvet due to concerns about chronic wasting disease.<ref name="Hansen">{{cite web|last=Hansen| first=Ray| title=Elk Profile|date=November 2006| publisher=Agricultural Marketing Resource Center |url=http://www.agmrc.org/agmrc/commodity/livestock/elk/elkprofile.htm|archive-url= https://web.archive.org/web/20070928000404/http://www.agmrc.org/agmrc/commodity/livestock/elk/elkprofile.htm |archive-date=2007-09-28| access-date=2010-12-04}}</ref>

Elk hoof disease was first noticed in the state of Washington in the late 1990s in the Cowlitz River basin, with sporadic reports of deformed hooves. Since then, the disease has spread rapidly with increased sightings throughout southwest Washington and into Oregon. The disease is characterised by deformed, broken, or missing hooves and leads to severe lameness in elk. The primary cause is not known, but it is associated with treponeme bacteria, which are known to cause digital dermatitis in commercial livestock. The mode of transmission is also not known, but it appears to be highly contagious among elk. Studies are being undertaken by government departments to determine how to halt or eliminate the disease.<ref>{{cite web |url=http://wdfw.wa.gov/conservation/health/hoof_disease/ |title=Treponeme associated hoof disease in Washington elk |author=<!--Not stated--> |date=2017 |publisher=Washington Department of Fish & Wildlife |access-date=10 August 2017 |archive-url=https://web.archive.org/web/20170820050237/http://wdfw.wa.gov/conservation/health/hoof_disease/ |archive-date=20 August 2017 }}</ref><ref>{{cite news |last=Hogan |first=Jackson |date=1 June 2017 |title=WSU: Elk hoof disease will not be easy fix |url=http://www.columbian.com/news/2017/jun/01/wsu-elk-hoof-disease-will-not-be-easy-fix/ |work=The Columbian |location=Longview, Washington |access-date=10 August 2017 |archive-date=16 January 2021 |archive-url=https://web.archive.org/web/20210116133056/https://www.columbian.com/news/2017/jun/01/wsu-elk-hoof-disease-will-not-be-easy-fix/ |url-status=live }}</ref><ref>{{cite web |url=http://www.dfw.state.or.us/wildlife/health_program/docs/ElkHoofDiseaseFactSheetFinal.pdf |title=Elk Hoof Disease Fact Sheet |author=<!--Not stated--> |publisher=Oregon Department of Fish and Wildlife |access-date=10 August 2017 |archive-date=9 June 2017 |archive-url=https://web.archive.org/web/20170609230318/http://www.dfw.state.or.us/wildlife/health_program/docs/ElkHoofDiseaseFactSheetFinal.pdf |url-status=live }}</ref>
==Distribution and status== thumb|Bull elk ''bugling'' during the rut
The elk ranges from central Asia through to Siberia and east Asia and in North America. They can be found in open deciduous woodlands, boreal forests, upland moors, mountainous areas and grasslands. The International Union for Conservation of Nature and Natural Resources (IUCN) list the species as least-concern species.<ref name="iucn" /> The habitat of Siberian elk in Asia is similar to that of the Rocky Mountain subspecies in North America. During the Late Pleistocene their range was much more extensive, being distributed across Eurasia, with remains being found as far west as France. These populations are most closely related to modern Asian populations of the elk. Their range collapsed at the start of the Holocene, possibly because they were specialized to cold periglacial tundra-steppe habitat. When this environment was replaced largely by closed forest the red deer might have outcompeted the elk. Relictual populations survived into the early Holocene (until around 3000 years ago) in southern Sweden and the Alps, where the environment remained favorable.<ref>{{Cite journal |last=Croitor |first=Roman |date=December 2019 |title=A new form of wapiti ''Cervus canadensis'' Erxleben, 1777 (Cervidae, Mammalia) from the Late Pleistocene of France |journal=Palaeoworld |volume=29 |issue=4 |language=en |pages=789–806 |doi=10.1016/j.palwor.2019.12.001 |s2cid=213500978|url=https://hal.science/hal-03126334/file/S1871174X19301295.pdf }}</ref> Elk were also present in the early Holocene of central Alaska, where it was the main hunted animal along with bison, and survived in Yukon until around 1400 BP (550 AD).<ref>Potter, B.

As of 2014, population figures for all North American elk subspecies were around one million. Prior to the European colonization of North America, there were an estimated 10 million on the continent.<ref>{{cite web|title=Rocky Mountain Elk|publisher=U.S. Fish & Wildlife Service |url=https://www.fws.gov/refuge/Cold_Springs/Wildlife_Habitat/Elk.html|access-date=3 December 2020 |archive-date=28 November 2020|archive-url=https://web.archive.org/web/20201128202958/https://www.fws.gov/refuge/Cold_Springs/Wildlife_Habitat/Elk.html|url-status=live}}</ref>

A male elk can produce {{convert|10|to|11|kg|lb}} of antler velvet annually and on ranches in the United States, Canada and New Zealand, it is collected and sold to markets in East Asia, where it is used in medicine.

Antlers are also used in artwork, furniture and other novelty items.
