The '''moose''' ({{plural form}}: 'moose'; used in North America) or '''elk''' ({{plural form}}: 'elk' or 'elks'; used in Eurasia) ('''''Alces alces''''') is the world's tallest, largest and heaviest extant species of deer and the only species in the genus '''''Alces'''''. It is also the tallest, and the second-largest, land animal in North America, falling short only to the American bison in body mass. Most adult male moose have broad, palmate ("open-hand shaped") antlers; other members of the deer family have pointed antlers with a dendritic ("twig-like") configuration. Moose inhabit the circumpolar boreal forests or temperate broadleaf and mixed forests of the Northern Hemisphere, thriving in cooler, temperate areas as well as subarctic climates.

Hunting shaped the relationship between moose and humans, both in Eurasia and North America. Prior to the colonial era (around 1600–1700 CE), moose were one of many valuable sources of sustenance for certain tribal groups and First Nations. Hunting and habitat loss have reduced the moose's range; this fragmentation has led to sightings of "urban moose" in some areas.

The moose has been reintroduced to some of its former habitats. Currently, the greatest populations occur in Canada, where they can be found in all provinces and territories except Nunavut and Prince Edward Island. Additionally, substantial numbers of moose are found in Alaska, New England (with Maine having the most of the contiguous United States), New York State, Fennoscandia, the Baltic states, the Caucasus region, Belarus, Poland, Eastern Europe, Mongolia, Kazakhstan, and Russia. In the United States (outside of Alaska and New England), most moose are found further to the north, west and northeast (including Colorado, Idaho, Michigan, Minnesota, Montana, North Dakota, Utah, Vermont, Wisconsin and Wyoming), and individuals have been documented wandering as far south as western Oklahoma, northeastern Arizona and northwestern New Mexico.

Predominantly a browser, the moose's diet consists of both terrestrial and aquatic vegetation, depending on the season, with branches, twigs and dead wood making up a large portion of their winter diet. Predators of moose include wolves, bears, humans, wolverines (rarely, though may take calves), and (rarely, if swimming in the ocean) orcas. Unlike most other deer species, moose do not form herds and are solitary animals, aside from calves who remain with their mother until the cow begins estrus again (typically 18 months after the birth of a calf). At this point, the cow chases her calf away. Although generally slow-moving and sedentary, moose can become defensively aggressive, and move very quickly if angered or startled. Their mating season in the autumn features energetic fights between males competing for a female.

Moose have played a prominent role in the culture of people in the Northern Hemisphere. Evidence suggests they were hunted by humans as far back as the most recent Ice Age.<ref>{{Cite journal |last=Larsson |first=Thomas B. |last2=Rosqvist |first2=Gunhild |last3=Ericsson |first3=Göran |last4=Heinerud |first4=Jans |date=2012-08-13 |title=Climate Change, Moose and Humans in Northern Sweden 4000 cal. yr BP |url=https://doi.org/10.36368/jns.v6i1.693 |journal=Journal of Northern Studies |volume=6 |issue=1 |pages=9–30 |doi=10.36368/jns.v6i1.693 |issn=2004-4658}}</ref>

=== Etymology ===

''Alces alces'' is called a "moose" in North American English, but an "elk" in British English.<ref name="OED">{{cite web|year=1989|orig-date=1891|title=elk, ''n''. 1|url=http://www.oed.com/view/Entry/60507|access-date=January 15, 2021|work=Oxford English Dictionary|edition=2nd|archive-date=March 9, 2021|archive-url=https://web.archive.org/web/20210309225208/https://www.oed.com/view/Entry/60507|url-status=live}}</ref> The word "elk" in North American English refers to a completely different species of deer, ''Cervus canadensis'', also called the wapiti (from Algonquin). A mature male moose is called a bull, a mature female a cow, and an immature moose of either sex a calf.

In Classical Antiquity, the animal was known as {{Lang|grc|ἄλκη|}} ({{Transliteration|grc|álkē}})<ref>{{LSJ|a)/lkh2|ἄλκη|ref}}.</ref> in Greek and {{Lang|la|alces}}<ref>{{L&S|alces|ref}}</ref> in Latin, words probably borrowed from a Germanic language or another language of northern Europe.<ref name="OED" /> By the 8th century, during the Early Middle Ages, the species 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" /> Later, the species became known in Middle English as {{lang|enm|elk}}, {{lang|enm|elcke}}, or {{lang|enm|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|year=2012|title=alce, ''n.''|url=http://www.oed.com/view/Entry/4677|access-date=January 15, 2021|work=Oxford English Dictionary|edition=3rd|archive-date=March 9, 2021|archive-url=https://web.archive.org/web/20210309225920/https://www.oed.com/view/Entry/4677|url-status=live}}</ref>

The word "elk" remained in usage because of English-speakers' familiarity with the species in Continental Europe; however, without any living animals around to serve as a reference, the meaning became rather vague, and by the 17th century "elk" had a meaning similar to "large deer".<ref name=":1">{{Cite book|last1=Mallory|first1=J. P.|title=The Oxford introduction to Proto-Indo-European and the Proto-Indo-European World|last2=Adams|first2=D. Q.|publisher=Oxford University Press|year=2006|pages=133–134}}</ref> Dictionaries of the 18th century simply described "elk" as a deer that was "as large as a horse".<ref>Bailey, Nathan (1731). ''An Universal Etymological English Dictionary'' Royal Exchange. Page EL--EM.</ref>

The word "moose" had first entered English by 1606<ref>{{OED|moose}}</ref> and is borrowed from the Algonquian languages (compare the Narragansett {{lang|xnt|moos}} and Eastern Abenaki {{lang|aaq|mos}}; according to early sources, these were likely derived from ''moosu'', meaning {{gloss|he strips off}}),<ref>{{OED|moose|access-date=February 16, 2011}}</ref> and possibly involved forms from multiple languages mutually reinforcing one another. The Proto-Algonquian form was ''*mo·swa''.<ref>{{dictionary.com|moose|access-date=October 25, 2011}}</ref>

=== Antlers ===

[[File:Alces alces 8492.JPG|thumb|Growing antlers are covered with a soft, furry covering called "velvet". Blood vessels in the velvet transport nutrients to support antler growth.]]
[[File:Moose Skull sideview.jpg|thumb|Skull of a moose]]

Bull moose have antlers like other members of the deer family. The size and growth rate of antlers is determined by diet and age.<ref name=Rodgers2001a /> Size and symmetry in the number of antler points signals bull moose health and cows may select mates based on antler size and symmetry.<ref>{{cite journal |title=Fluctuating asymmetry in the antlers of moose ( Alces alces ): does it signal male quality? |journal=Proceedings of the Royal Society of London. Series B: Biological Sciences |date=22 December 1993 |volume=254 |issue=1341 |pages=251–255 |doi=10.1098/rspb.1993.0154|s2cid=129492491  |issn=0962-8452 }}</ref> Bull moose use their antlers to display dominance, to discourage competition, and to spar or fight rivals.<ref name=Rodgers2001a />

The male's antlers grow as cylindrical beams projecting on each side of the head at right angles to the midline of the skull, and then fork. The lower prong of this fork may be either simple, or divided into two or three tines, with some flattening. Most moose have antlers that are broad and palmate (flat) with tines (points) along the outer edge.<ref name=Rodgers2001a>{{citation|title=Moose|first=Art|last=Rodgers|publisher=Voyager Press|chapter=Appearance and characteristics|year=2001|pages=[https://archive.org/details/moose0000rodg/page/24 24–27]|isbn=978-0-89658-521-8|chapter-url=https://archive.org/details/moose0000rodg/page/24}}</ref> Within the ecologic range of the moose in Europe, northern populations display the palmate pattern of antlers, while the antlers of European moose residing the southerly portion of its range are typically of the cervina dendritic pattern and comparatively small, perhaps due to evolutionary pressures of hunting by humans, who prize the large palmate antlers. European moose with antlers intermediate between the palmate and the dendritic form are found in the middle of the north-south range.<ref>{{cite journal |last1=Nygrén |first1=Tuire |first2=Jyrki |last2=Pusenius |first3=Raisa |last3=Tiilikainend |first4=Jan |last4=Korpelainen |title=Moose Antler Type Polymorphism: Age and Weight Dependent Phenotypes and Phenotype Frequencies in Space and Time |journal=Annales Zoologici Fennici |volume=44 |number=6 |date=2007 |pages=445–61 |access-date=May 2, 2020 |jstor=23736846 |url=https://core.ac.uk/download/pdf/15167953.pdf#page=22 |archive-date=October 12, 2021 |archive-url=https://web.archive.org/web/20211012221937/https://core.ac.uk/download/pdf/15167953.pdf#page=22 |url-status=live }}</ref> Moose with antlers have more acute hearing than those without antlers; a study of trophy antlers using a microphone found that the palmate antler acts as a parabolic reflector, amplifying sound at the moose's ear.<ref>{{cite journal |doi=10.1007/s10344-007-0165-4 |title=Palmated antlers of moose may serve as a parabolic reflector of sounds |journal=European Journal of Wildlife Research |volume=54 |issue=3 |pages=533–5 |year=2008 |last1=Bubenik |first1=George A. |last2=Bubenik |first2=Peter G. |bibcode=2008EJWR...54..533B |s2cid=44737101 |url=https://engagedscholarship.csuohio.edu/cgi/viewcontent.cgi?article=1221&context=scimath_facpub |access-date=2019-10-18 |archive-date=2020-03-14 |archive-url=https://web.archive.org/web/20200314062052/https://engagedscholarship.csuohio.edu/cgi/viewcontent.cgi?article=1221&context=scimath_facpub |url-status=live |url-access=subscription }}

The antlers of mature Alaskan adult bull moose (5 to 12 years old) have a normal maximum spread greater than {{convert|200|cm|sp=us}}. By the age of 13, moose antlers decline in size and symmetry. The widest spread recorded was {{convert|210|cm|sp=us}} across. An Alaskan moose also holds the record for the heaviest weight at {{convert|36|kg|0|sp=us}}.<ref name=Rodgers2001a />

Antler beam diameter, not the number of tines, indicates age.<ref name=Rodgers2001a /> In North America, moose (''A. a. americanus'') antlers are usually larger than those of Eurasian moose and have two lobes on each side, like a butterfly. Eurasian moose antlers resemble a seashell, with a single lobe on each side.<ref name=Rodgers2001a /> In the North Siberian moose (''A. a. bedfordiae''), the posterior division of the main fork divides into three tines, with no distinct flattening. In the common moose (''A. a. alces'') this branch usually expands into a broad palmation, with one large tine at the base and a number of smaller snags on the free border. There is, however, a Scandinavian breed of the common moose in which the antlers are simpler and recall those of the East Siberian animals. The palmation appears to be more marked in North American moose than in the typical Scandinavian moose.

[[File:alces alces.jpg|thumb|Young female (''A. a. americana'') in early June.]]
After the mating season males drop their antlers to conserve energy for the winter. A new set of antlers will then regrow in the spring. Antlers take three to five months to fully develop, making them one of the fastest growing animal organs. Antler growth is "nourished by an extensive system of blood vessels in the skin covering, which contains numerous hair follicles that give it a 'velvet' texture."<ref name=Rodgers2001a /> This requires intense grazing on a highly-nutritious diet. By September the velvet is removed by rubbing and thrashing which changes the colour of the antlers. Immature bulls may not shed their antlers for the winter, but retain them until the following spring. Birds, carnivores and rodents eat dropped antlers as they are full of protein and moose themselves will eat antler velvet for the nutrients.<ref name=Rodgers2001a />

If a bull moose is castrated, either by accidental or chemical means, he will shed his current set of antlers within two weeks and then immediately begin to grow a new set of misshapen and deformed antlers that he will wear the rest of his life without ever shedding again; similarly deformed antlers can result from a deficiency of testosterone caused by cryptorchidism or old age.<ref name='franzmann'>{{cite book

In extremely rare circumstances, a cow moose may grow antlers.

===Proboscis and olfaction===
The moose proboscis is distinctive among living cervids due to its large size; it also features nares that can be sealed shut when the moose is browsing aquatic vegetation. The moose proboscis likely evolved as an adaptation to aquatic browsing, with loss of the rhinarium, and development of a superior olfactory column separate from an inferior respiratory column.<ref name="Pagano, Anthony Santino 2019">Pagano, Anthony Santino, Jeffrey T. Laitman, Kurt Albertine, and Samuel Marquez. "Evolution of the proboscis in the moose, Alces alces: Evidence from Morphology and Ecology." The FASEB Journal 33, no. 1_supplement (2019): 767-19.</ref> This separation contributes to the moose's keen sense of smell, which they employ to detect water sources, to find food under snow, and to detect mates or predators.<ref>Márquez, Samuel, Anthony S.

===Hooves===
[[File:Tracksdeepsnow.JPG|thumb|left|upright|Long legs allow moose to wade easily through deep water or snow.]]
As with all members of the order Artiodactyla (even-toed ungulates), moose feet have two large keratinized hooves corresponding to the third and fourth toe, with two small posterolateral dewclaws (vestigial digits), corresponding to the second and fifth toe. The hoof of the fourth digit is broader than that of the third digit, while the inner hoof of the third digit is longer than that of the fourth digit. This foot configuration may favor striding on soft ground.<ref>Keller, Anna, Marcus Clauss, Evelyne Muggli, and Karl Nuss. "Even-toed but uneven in length: the digits of artiodactyls." Zoology 112, no. 4 (2009): 270-278.</ref> The moose hoof splays under load, increasing surface area, which limits sinking of the moose foot into soft ground or snow, and which increases efficiency when swimming. The body weight per footprint surface area of the moose foot is intermediate between that of the pronghorn foot, (which have stiff feet lacking dewclaws—optimized for high-speed running) and the caribou foot (which are more rounded with large dewclaws, optimized for walking in deep snow). The moose's body weight per surface area of footprint is about twice that of the caribou.<ref>Lundmark, Caroline. Morphological and behavioral adaptations of moose to climate, snow, and forage.

===Skin and fur===
Moose skin is typical of the deer family. Moose fur consists of four types of hair: eyelashes, whiskers, guard hairs and wool hairs. Hair length and hair density varies according to season, age, and body region.<ref>{{cite journal |last1=Sokolov |first1=V. E. |last2=Chernova |first2=O.

Moose lack upper front teeth, but have eight sharp incisors on the lower jaw. They also have a tough tongue, lips and gums, which aid in the eating of woody vegetation. Moose have six pairs of large, flat molars and, ahead of those, six pairs of premolars, to grind up their food. A moose's upper lip is very sensitive, to help distinguish between fresh shoots and harder twigs, and is prehensile, for grasping their food. In the summer, moose may use this prehensile lip for grabbing branches and pulling, stripping the entire branch of leaves in a single mouthful, or for pulling forbs, like dandelions, or aquatic plants up by the base, roots and all.<ref name=Rodgers2001>{{citation|title=Moose|first=Art|last=Rodgers|publisher=Voyager Press|year=2001|page=[https://archive.org/details/moose0000rodg/page/34 34]|isbn=978-0-89658-521-8|url=https://archive.org/details/moose0000rodg/page/34}}</ref><ref>{{cite book |title=Seasons of the Moose |first1=Jennie |last1=Promack |first2=Thomas J. |last2=Sanker |publisher=Gibbs Smith |date=1992 |page=21}}</ref> A moose's diet often depends on its location, but they seem to prefer the new growths from deciduous trees with a high sugar content, such as white birch, trembling aspen and striped maple, among many others.<ref>{{cite web |url=http://www.mooseworld.com/diet.htm |title=Moose diet |archive-url=https://web.archive.org/web/20101125060007/http://mooseworld.com/diet.htm |archive-date=November 25, 2010 |website=Mooseworld |access-date=January 9, 2011}}</ref> To reach high branches, a moose may bend small saplings down, using its prehensile lip, mouth or body.

Moose are excellent swimmers and are known to wade into water to eat aquatic plants. This trait serves a second purpose in cooling down the moose on summer days and ridding itself of black flies.

In some areas, moose are the primary source of food for wolves. Moose usually flee upon detecting wolves. Wolves usually follow moose at a distance of {{convert|100|to|400|m|ft|-2|sp=us}}, occasionally at a distance of {{convert|2|to|3|km|frac=2|spell=in|sp=us}}. Attacks from wolves against young moose may last seconds, though sometimes they can be drawn out for days with adults. Sometimes, wolves will chase moose into shallow streams or onto frozen rivers, where their mobility is greatly impeded. Moose will sometimes stand their ground and defend themselves by charging at the wolves or lashing out at them with their powerful hooves. Wolves typically kill moose by tearing at their haunches and perineum, causing massive blood loss. Occasionally, a wolf may immobilize a moose by biting its sensitive nose, the pain of which can paralyze a moose.<ref name="Graves">{{cite book|author = Graves, Will|url = http://www.wolvesinrussia.com/|title = Wolves in Russia: Anxiety throughout the ages|year = 2007|page = 222|isbn = 978-1-55059-332-7|publisher = Detselig Enterprises|location = Calgary|oclc = 80431846|archive-url = https://web.archive.org/web/20090802182158/http://www.wolvesinrussia.com/|archive-date = August 2, 2009}}</ref> Wolf packs primarily target calves and elderly animals, but can and will take healthy, adult moose.

Research into moose predation suggests that their response to perceived threats is learned rather than instinctual. In practical terms this means moose are more vulnerable in areas where wolf or bear populations were decimated in the past but are now rebounding. These same studies suggest, however, that moose learn quickly and adapt, fleeing an area if they hear or smell wolves, bears, or scavenger birds such as ravens.<ref>Berger, Joel; Swenson, Jon E.; Persson, Inga-Lill [https://web.archive.org/web/20130512211113/http://www.highbeam.com/doc/1G1-70741145.html Recolonizing Carnivores and Naive Prey: Conservation Lessons from Pleistocene Extinctions.] ''Science'' September 2, 2001</ref>

===Parasites===
Moose typically carry a heavy burden of parasites, both externally and internally. Parasitosis is an important cause of moose morbidity and mortality and also contributes to vulnerability to predators.<ref>{{cite journal |last1=Debow |first1=Jacob |last2=Blouin |first2=Joshua |last3=Rosenblatt |first3=Elias |last4=Alexander |first4=Cedric |last5=Gieder |first5=Katherina |last6=Cottrell |first6=Walter |last7=Murdoch |first7=James |last8=Donovan |first8=Therese |title=Effects of Winter Ticks and Internal Parasites on Moose Survival in Vermont, USA |journal=The Journal of Wildlife Management |date=September 2021 |volume=85 |issue=7 |pages=1423–1439 |doi=10.1002/jwmg.22101|doi-access=free |bibcode=2021JWMan..85.1423D }}</ref> Ectoparasites of moose include the moose nose bot fly,<ref>{{cite journal |last1=Rolandsen |first1=Christer M. |last2=Madslien |first2=Knut |last3=Ytrehus |first3=Bjørnar |last4=Hamnes |first4=Inger Sofie |last5=Solberg |first5=Erling J. |last6=Mysterud |first6=Atle |last7=Vikøren |first7=Turid |last8=Våge |first8=Jørn |last9=Hanssen |first9=Oddvar |last10=Miller |first10=Andrea L. |title=Distribution, prevalence and intensity of moose nose bot fly (Cephenemyia ulrichii) larvae in moose (Alces alces) from Norway |journal=International Journal for Parasitology: Parasites and Wildlife |date=August 2021 |volume=15 |pages=120–126 |doi=10.1016/j.ijppaw.2021.04.012|pmid=33996444 |pmc=8105593 |bibcode=2021IJPPW..15..120R |hdl=10852/85965 |hdl-access=free }}</ref> and winter ticks.<ref>{{cite journal |last1=Ellingwood |first1=Daniel D. |last2=Pekins |first2=Peter J. |last3=Jones |first3=Henry |last4=Musante |first4=Anthony R. |title=Evaluating moose Alces alces population response to infestation level of winter ticks Dermacentor albipictus |journal=Wildlife Biology |date=16 June 2020 |volume=2020 |issue=2 |page=1 |doi=10.2981/wlb.00619 |s2cid=220526796 |url=https://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=3339&context=icwdm_usdanwrc |doi-access=free |bibcode=2020WildB202000619E |access-date=28 October 2021 |archive-date=17 May 2022 |archive-url=https://web.archive.org/web/20220517041202/https://digitalcommons.unl.edu/cgi/viewcontent.cgi?article=3339&context=icwdm_usdanwrc |url-status=live }}</ref> Endoparasites of moose include dog tapeworm, meningeal worm,<ref>{{cite journal |last1=Wünschmann |first1=Arno |last2=Armien |first2=Anibal G. |last3=Butler |first3=Erika |last4=Schrage |first4=Mike |last5=Stromberg |first5=Bert |last6=Bender |first6=Jeff B. |last7=Firshman |first7=Anna M. |last8=Carstensen |first8=Michelle |title=NECROPSY FINDINGS IN 62 OPPORTUNISTICALLY COLLECTED FREE-RANGING MOOSE (ALCES ALCES) FROM MINNESOTA, USA (2003–13) |journal=Journal of Wildlife Diseases |date=1 January 2015 |volume=51 |issue=1 |pages=157–165 |doi=10.7589/2014-02-037|pmid=25390764 |s2cid=19770221 }}</ref> lungworm, and roundworm.

===Social structure and reproduction===
[[File:Riddle of the racks.jpg|thumb|Display at the Kenai National Wildlife Refuge of the skulls of two bulls who apparently died after their antlers became locked during a fight.]]
Moose are mostly diurnal. They are generally solitary with the strongest bonds between mother and calf. Although moose rarely gather in groups, there may be several in close proximity during the mating season.

Rutting and mating occurs in September and October. During the rut, mature bulls will cease feeding completely for a period of approximately two weeks; this fasting behavior has been attributed to neurophysiological changes related to redeployment of olfaction for detection of moose urine and moose cows.<ref>Miquelle, Dale G. "Why don't bull moose eat during the rut?." Behavioral Ecology and Sociobiology 27, no. 2 (1990): 145-151.</ref> The males are polygynous and will seek several females to breed with. During this time both sexes will call to each other. Males produce heavy grunting sounds that can be heard from up to {{convert|500|m}} away, while females produce wail-like sounds.<ref>{{cite web|author=DW Hartt, Data|first2=Web |last2=Coordinator |url=http://www.nwtwildlife.com/NWTwildlife/moose/reproduction.htm |title=Moose Reproduction |access-date=February 16, 2011 |archive-url=https://web.archive.org/web/20080424001305/http://www.nwtwildlife.com/NWTwildlife/moose/reproduction.htm |archive-date=April 24, 2008}}</ref> Males will fight for access to females.

===Aggression===
Moose are not typically aggressive towards humans, but will be aggressive when provoked or frightened. Moose attack more people than bears and wolves combined, but usually with only minor consequences. In the Americas, moose injure more people than any other wild mammal; worldwide, only hippopotamuses injure more.<ref>Adventure Guide Inside Passage & Coastal Alaska By Ed Readicker-Henderson, Lynn Readicker-Henderson – Hunter Publishing 2006 Page 49</ref> When harassed or startled by people or in the presence of a dog, moose may charge. Also, as with bears or most wild animals, moose accustomed to being fed by people may act aggressively when denied food. During the fall mating season, bulls may be aggressive toward humans. Cows are protective of young calves and will attack humans who come close, especially if they come between mother and calf. Moose are not territorial, do not view humans as food, and usually will not pursue humans who run away.<ref>{{cite web |url=https://www.adfg.alaska.gov/index.cfm?adfg=species.main |title=What To Do About Aggressive Moose, Division of Wildlife Conservation, Alaska Department of Fish and Game |publisher=wildlife.alaska.gov |access-date=November 6, 2009 |url-status=live |archive-url=https://web.archive.org/web/20091105013619/http://www.wildlife.alaska.gov/index.cfm?adfg=aawildlife.agmoose |archive-date=November 5, 2009 }}</ref>

[[File:Bull moose growing new antlers and shedding fur.JPG|thumb|A bull, disturbed by the photographer, lowers his head and raises his hackles.]]
Moose are unpredictable. They are most likely to attack if annoyed or harassed, or if approached too closely. A moose that has been harassed may vent its anger on anyone in the vicinity, and they often do not make distinctions between their tormentors and innocent passersby.{{citation needed|date=March 2017}} Moose are very limber animals with highly flexible joints and sharp, pointed hooves, and are capable of kicking with both front and back legs. Moose can kick in all directions, including sideways. Thus, there is no safe side from which to approach. Moose often give warning signs prior to attacking, displaying aggression by means of body language. Maintained eye contact is usually the first sign of aggression, while laid-back ears or a lowered head is a sign of agitation. When the hairs on the back of the moose's neck and shoulders (hackles) stand up, a charge is usually imminent. The Anchorage Visitor Centers warn tourists that "...a moose with its hackles raised is a thing to fear."<ref>''Adventure Guide Alaska Highway'' By Ed Readicker-Henderson, Lynn Readicker-Henderson – Hunter Publishing 2006 Page 416</ref><ref>''Explorer's Guide 50 Hikes Around Anchorage'' By Lisa Maloney – The Countryman Press 2010 Page 16</ref><ref>''Field & Stream'' Aug 2002 – Page 75--77</ref><ref>''Wilderness Camping & Hiking'' By Paul Tawrell – Exxa Nature 2007 Page 161</ref>

Moose cows are more likely to emit protest moans when courted by small males. This attracts the attention of large males, promotes male-male competition and violence, reduces harassment of cows by small males, and increases mating opportunities with large males.<ref>{{cite journal |last1=Bowyer |first1=R.

Moose often show aggression to other animals as well, especially predators. Bears are common predators of moose calves and, rarely, adults. Alaskan moose have been reported to successfully fend off attacks from both black and brown bears. Moose have been known to stomp attacking wolves, which makes them less preferred as prey to the wolves. Moose are fully capable of killing bears and wolves. In one rare event, a female moose killed two adult male wolves.<ref name="v.106 (1992)">{{Cite book|url=https://www.biodiversitylibrary.org/page/34347342|title=v.106 (1992) – The Canadian field-naturalist|date=21 February 1992|volume=106|access-date=22 August 2021|archive-date=22 August 2021|archive-url=https://web.archive.org/web/20210822183532/https://www.biodiversitylibrary.org/page/34347342|url-status=live}}</ref><ref>Weaver, J.L., C.

European moose are often more aggressive than North American moose, such as the moose in Sweden, which often become very agitated at the sight of a predator. However, like all ungulates known to attack predators, the more aggressive individuals are always darker in color, with the darkest coloring usually in areas facing the opponent, thus serving as a natural warning to other animals.<ref name="World Page 237"/>

== Habitat, range, and distribution ==

===Habitat===
[[File:Thermal image of a cow moose during winter.jpg|thumb|Thermal image of a cow moose in the winter. Her thick, coarse fur with hollow hairs only measures an average of 8.3 °C (15 °F) above the ambient temperature of {{Convert|-23|C|F}}, showing low heat-loss.]]

Moose require habitat with adequate edible plants (e.g., pond grasses, young trees and shrubs), cover from predators, and protection from extremely hot or cold weather. Moose travel among different habitats with the seasons to address these requirements.<ref name="autogenerated1">{{cite report|url= https://extension.unh.edu/resources/files/Resource003858_Rep5484.pdf|title= New Hampshire's moose population vs climate change|first= Kristine|last= Rines|publisher= New Hampshire Fish and Game Department|access-date= May 15, 2018|archive-url= https://web.archive.org/web/20180516103753/https://extension.unh.edu/resources/files/Resource003858_Rep5484.pdf|archive-date= May 16, 2018|url-status= live}}</ref> Moose are cold-adapted mammals with thickened skin, dense, heat-retaining coat, and a low surface:volume ratio, which provides excellent cold tolerance but poor heat tolerance. Moose survive hot weather by accessing shade or cooling wind, or by immersion in cool water. In hot weather, moose are often found wading or swimming in lakes or ponds. When heat-stressed, moose may fail to adequately forage in summer and may not gain adequate body fat to survive the winter. Also, moose cows may not calve without adequate summer weight gain. Moose require access to both young forest for browsing and mature forest for shelter and cover. Forest disturbed by fire and logging promotes the growth of fodder for moose. Moose also require access to mineral licks, safe places for calving and aquatic feeding sites.<ref name="autogenerated1"/>

Moose avoid areas with little or no snow as this increases the risk of predation by wolves and avoid areas with deep snow, as this impairs mobility. Thus, moose select habitat on the basis of trade-offs between risk of predation, food availability, and snow depth.<ref>Dussault, Christian, Jean‐Pierre Ouellet, Réhaume Courtois, Jean Huot, Laurier Breton, and Hélène Jolicoeur. "Linking moose habitat selection to limiting factors." Ecography 28, no. 5 (2005): 619-628.</ref> With reintroduction of bison into boreal forest, there was some concern that bison would compete with moose for winter habitat, and thereby worsen the population decline of moose. However, this does not appear to be a problem. Moose prefer sub-alpine shrublands in early winter, while bison prefer wet sedge valley meadowlands in early winter. In late winter, moose prefer river valleys with deciduous forest cover or alpine terrain above the tree line, while bison preferred wet sedge meadowlands or sunny southern grassy slopes.<ref>{{cite journal|last1=Jung|first1= Thomas S.|first2= Sophie M.|last2= Czetwertynski|first3= Fiona K.

===North America===
After expanding for most of the 20th century, the moose population of North America has been in steep decline since the 1990s. Populations expanded greatly with improved habitat and protection, but now the moose population is declining rapidly.<ref name="Robbins">{{cite news|last=Robbins|first=Jim|title=Moose Die-Off Alarms Scientists|url=https://www.nytimes.com/2013/10/15/science/earth/something-is-killing-off-the-moose.html|access-date=December 6, 2013|newspaper=New York Times|date=October 14, 2013|archive-url=https://web.archive.org/web/20131210211456/http://www.nytimes.com/2013/10/15/science/earth/something-is-killing-off-the-moose.html |archive-date=December 10, 2013|url-status=live}}</ref> This decline has been attributed to opening of roads and landscapes into the northern range of moose, allowing deer to become populous in areas where they were not previously common.

In northeastern North America, the Eastern moose's history is very well documented: moose meat was a staple in the diet of indigenous peoples for centuries. The common name "moose" was brought into English from the word used by those who lived in present day coastal Rhode Island. The indigenous
people often used moose hides for leather and its meat as an ingredient in pemmican, a type of dried jerky used as a source of sustenance in winter or on long journeys.<ref>{{cite book |first=Nancy |last=Cappelloni |title=Cranberry Cooking for All Seasons |url=https://books.google.com/books?id=u-uomE8l8g8C&pg=PA14 |access-date=June 25, 2011 |date=November 2002 |publisher=Spinner Publications |isbn=978-0-932027-71-9 |page=14 |archive-url=https://web.archive.org/web/20131009073801/http://books.google.com/books?id=u-uomE8l8g8C&pg=PA14 |archive-date=October 9, 2013 |url-status=live }}</ref>

The historical range of the subspecies extended from well into Quebec, the Maritimes, and Eastern Ontario south to include all of New England finally ending in the very northeastern tip of Pennsylvania in the west, cutting off somewhere near the mouth of the Hudson River in the south. The moose has been extinct in much of the eastern U.S. for as long as 150 years, due to colonial era overhunting and destruction of its habitat: Dutch, French, and British colonial sources all attest to its presence in the mid 17th century from Maine south to areas within {{convert|100|mi|km|order=flip|sp=us}} of present-day Manhattan. However, by the 1870s, only a handful of moose existed in this entire region in very remote pockets of forest; less than 20% of suitable habitat remained.<ref name="scholarworks.umass.edu">{{cite thesis|url=http://scholarworks.umass.edu/cgi/viewcontent.cgi?article=1791&context=theses|title=STATUS, MOVEMENTS, AND HABITAT USE OF MOOSE IN MASSACHUSETTS|format=PDF|first=David W.|last=Wattles|year=2011|degree=M.S.|publisher=University of Massachusetts Amherst|access-date=November 22, 2013|archive-url=https://web.archive.org/web/20131202232721/http://scholarworks.umass.edu/cgi/viewcontent.cgi?article=1791&context=theses|archive-date=December 2, 2013|url-status=live}}</ref>

In Europe, moose are currently found in large numbers throughout Norway, Sweden, Finland, Latvia, Estonia, Poland, with more modest numbers in the southern Czech Republic, Belarus, and northern Ukraine. They are also widespread through Russia on up through the borders with Finland south towards the border with Estonia, Belarus and Ukraine and stretching far away eastwards to the Yenisei River in Siberia. The European moose was native to most temperate areas with suitable habitat on the continent and even Scotland from the end of the last Ice Age, as Europe had a mix of temperate boreal and deciduous forest. Up through Classical times, the species was certainly thriving in both Gaul and Magna Germania, as it appears in military and hunting accounts of the age. However, as the Roman era faded into medieval times, the beast slowly disappeared: soon after the reign of Charlemagne, the moose disappeared from France, where its range extended from Normandy in the north to the Pyrenees in the south. Farther east, it survived in Alsace and the Netherlands until the 9th century as the marshlands in the latter were drained and the forests were cleared away for feudal lands in the former. It was gone from Switzerland by the year 1000, from the western Czech Republic by 1300, from Mecklenburg in Germany by c. 1600, and from Hungary and the Caucasus since the 18th and 19th century, respectively.

By the early 20th century, the last strongholds of the European moose appeared to be in Fennoscandian areas and patchy tracts of Russia, with a few migrants found in what is now Estonia and Lithuania. The USSR and Poland managed to restore portions of the range within its borders (such as the 1951 reintroduction into Kampinos National Park and the later 1958 reintroduction in Belarus), but political complications limited the ability to reintroduce it to other portions of its range. Attempts in 1930 and again in 1967 in marshland north of Berlin were unsuccessful. At present in Poland, populations are recorded in the Biebrza river valley, Kampinos, and in Białowieża Forest. It has migrated into other parts of Eastern Europe and has been spotted in eastern and southern Germany.<ref>{{cite journal |last= Schnfeld |first= Fiona |title= Presence of moose (Alces alces) in Southeastern Germany |journal=European Journal of Wildlife Research |volume=55 |issue= 4 |page=449 |year=2009 |doi= 10.1007/s10344-009-0272-5|bibcode= 2009EJWR...55..449S |s2cid= 30772675 }}</ref><ref name=spieg120903/> Unsuccessful thus far in recolonizing these areas via natural dispersal from source populations in Poland, Belarus, Ukraine, Czech Republic, and Slovakia, it appears to be having more success migrating south into the Caucasus.

The East Asian moose populations confine themselves mostly to the territory of Russia, with much smaller populations in Mongolia and Northeastern China. Moose populations are relatively stable in Siberia and increasing on the Kamchatka Peninsula. In Mongolia and China, where poaching took a great toll on moose, forcing them to near extinction, they are protected, but enforcement of the policy is weak and demand for traditional medicines derived from deer parts is high.{{citation needed|date=June 2020}} In 1978, the Regional Hunting Department transported 45 young moose to the center of Kamchatka. These moose were brought from Chukotka, home to the largest moose on the planet. Kamchatka now regularly is responsible for the largest trophy moose shot around the world each season. As it is a fertile environment for moose, with a milder climate, less snow, and an abundance of food, moose quickly bred and settled along the valley of the Kamchatka River and many surrounding regions. The population in the past 20 years has risen to over 2,900 animals.

The size of the moose varies. Following Bergmann's rule, population in the south (''A. a. cameloides'') usually grow smaller, while moose in the north and northeast (''A. a. buturlini'') can match the imposing sizes of the Alaskan moose (''A. a. gigas'') and are prized by trophy hunters.

===New Zealand===
In 1900, an attempt to introduce moose into the Hokitika area failed; then in 1910 ten moose (four bulls and six cows) were introduced into Fiordland. This area is considered a less than suitable habitat, and subsequent low numbers of sightings and kills have led to some presumption of this population's failure.<ref name="king">{{Cite book| publisher = Oxford University Press in association with the Mammal Society, New Zealand Branch | isbn = 978-0-19-558320-5 | editor = Caroline King | title = The handbook of New Zealand mammals| location = Auckland, New Zealand| year = 1995}}</ref> The last proven sighting of a moose in New Zealand was in 1952.<ref>{{cite web|url=http://www.teara.govt.nz/en/deer-and-deer-farming/1|title=Deer and deer farming – Introduction and impact of deer|date=March 1, 2009|publisher=Te Ara – Encyclopedia of New Zealand|access-date=March 27, 2011|archive-url=https://web.archive.org/web/20111204003541/http://www.teara.govt.nz/en/deer-and-deer-farming/1|archive-date=December 4, 2011|url-status=live}}</ref> However, a moose antler was found in 1972, and DNA tests showed that hair collected in 2002 was from a moose.

It had a longer, narrower snout and a less-developed nasal cavity, more resembling that of a modern deer, lacking any sign of the modern moose-snout. Its face resembled that of the modern wapiti. However, the rest of its skull structure, skeletal structure and teeth bore strong resemblance to those features that are unmistakable in modern moose, indicating a similar diet. Its antlers consisted of a horizontal bar {{convert|2.5|m|ftin|abbr=on}} long, with no tines, ending in small palmations. Its skull and neck structure suggest an animal that fought using high-speed impacts, much like the Dall sheep, rather than locking and twisting antlers the way modern moose combat. Their long legs and bone structure suggest an animal that was adapted to running at high speeds over rough terrain.<ref name="ReferenceA">''Deer of the world: their evolution, behaviour, and ecology'' By Valerius Geist - Page 244-250</ref><ref name="North America' Page 178-181">''Morphological Change in Quaternary Mammals of North America'' by Robert Allen Martin, Anthony D.

''Libralces gallicus'' was followed by ''Cervalces carnutorum'' during the first half of the Early Pleistocene. ''Cervalces carnutorum'' was soon followed by a much larger species called ''Cervalces latifrons'' (broad-fronted stag-moose), which first appeared during the late Early Pleistocene.<ref name="Kevrekidis2017">{{cite web |author=Charalampos Kevrekidis, Dimitris S.

===History===
[[File:A moose with reflection in Grand Teton NP.jpg|thumb|A moose and its reflection]]
[[File:Collared muddy moose yearlings.jpg|thumb|Two young moose wearing radio tracking collars]]

European rock drawings and cave paintings reveal that moose have been hunted since the Stone Age. Excavations in Alby, Sweden, adjacent to the Stora Alvaret have yielded moose antlers in wooden hut remains from 6000&nbsp;BCE, indicating some of the earliest moose hunting in northern Europe. In northern Scandinavia one can still find remains of trapping pits used for hunting moose. These pits, which can be up to {{cvt|4|x|7|m|ft}} in area and {{cvt|2|m|ftin}} deep, would have been camouflaged with branches and leaves.{{citation needed|date=April 2024}} They would have had steep sides lined with planks, making it impossible for the moose to escape once it fell in. The pits are normally found in large groups, crossing the moose's regular paths and stretching over several kilometers. Remains of wooden fences designed to guide the animals toward the pits have been found in bogs and peat. In Norway, an early example of these trapping devices has been dated to around 3700&nbsp;BC.{{citation needed|date=April 2024}} Trapping elk in pits is an extremely effective hunting method. As early as the 16th&nbsp;century the Norwegian government tried to restrict their use; nevertheless, the method was in use until the 19th&nbsp;century.

The earliest recorded description of the moose is in Julius Caesar's ''Commentarii de Bello Gallico'', where it is described thus:

<blockquote>There are also [animals], which are called ''alces'' (moose). The shape of these, and the varied color of their skins, is much like roes, but in size they surpass them a little and are destitute of horns, and have legs without joints and ligatures; nor do they lie down for the purpose of rest, nor, if they have been thrown down by any accident, can they raise or lift themselves up. Trees serve as beds to them; they lean themselves against them, and thus reclining only slightly, they take their rest; when the huntsmen have discovered from the footsteps of these animals whither they are accustomed to betake themselves, they either undermine all the trees at the roots, or cut into them so far that the upper part of the trees may appear to be left standing. When they have leant upon them, according to their habit, they knock down by their weight the unsupported trees, and fall down themselves along with them.<ref>{{Cite book|publisher = Harper & brothers|last1 = Caesar|first1 = Julius|first2=Aulus|last2=Hirtius|title = Caesar's Commentaries on the Gallic and civil wars|chapter = XXVII|page = 154|year = 1879|isbn = 978-0-217-45287-8}}</ref></blockquote>

In book 8, chapter 16 of Pliny the Elder's ''Natural History'' from 77&nbsp;CE, the elk and an animal called achlis, which is presumably the same animal, are described thus:

<blockquote> ... there is, also, the elk, which strongly resembles our steers, except that it is distinguished by the length of the ears and of the neck. There is also the achlis, which is produced in the land of Scandinavia; it has never been seen in this city, although we have had descriptions of it from many persons; it is not unlike the moose, but has no joints in the hind leg. Hence, it never lies down, but reclines against a tree while it sleeps; it can only be taken by previously cutting into the tree, and thus laying a trap for it, as otherwise, it would escape through its swiftness. Its upper lip is so extremely large, for which reason it is obliged to go backwards when grazing; otherwise, by moving onwards, the lip would get doubled up.<ref>{{cite web |title= Pliny the Elder, The Natural History |editor= John Bostock |editor-link= John Bostock (physician) |editor2= Henry Thomas Riley |editor2-link= Henry Thomas Riley |access-date= 2009-11-08 |url= http://old.perseus.tufts.edu/cgi-bin/ptext?lookup=Plin.+Nat.+8.16 |archive-url= https://archive.today/20120713100336/http://old.perseus.tufts.edu/cgi-bin/ptext?lookup=Plin.+Nat.+8.16 |archive-date= 2012-07-13 }}</ref></blockquote>

Moose are hunted as a game species in many of the countries where they are found. Moose meat tastes, wrote Henry David Thoreau in ''The Maine Woods'', "like tender beef, with perhaps more flavour; sometimes like veal". While the flesh has protein levels similar to those of other comparable red meats (e.g. beef, deer and wapiti), it has a low fat content, and the fat that is present consists of a higher proportion of polyunsaturated fats than saturated fats.<ref>{{cite web |url=http://www.nutritiondata.com/facts-C00001-01c22al.html |title=Moose, meat, raw (Alaska Native) |publisher=Nutrition Data |access-date=February 16, 2011 |archive-url=https://web.archive.org/web/20080521095638/http://www.nutritiondata.com/facts-C00001-01c22aL.html |archive-date=May 21, 2008 |url-status=live }}</ref>

Dr. Valerius Geist, who emigrated to Canada from the Soviet Union, wrote in his 1999 book ''Moose: Behaviour, Ecology, Conservation'':

{{Blockquote|In Sweden, no fall menu is without a mouthwatering moose dish. The Swedes fence their highways to reduce moose fatalities and design moose-proof cars.

Boosting moose populations in Alaska for hunting purposes is one of the reasons given for allowing aerial or airborne methods to remove wolves in designated areas, e.g., Craig Medred: "A kill of 124 wolves would thus translate to [the survival of] 1488 moose or 2976 caribou or some combination thereof".<ref>{{Cite web|url=http://www.adn.com/news/alaska/wildlife/wolves/story/410461.html/|archive-url=https://web.archive.org/web/20090213031137/http://www.adn.com/news/alaska/wildlife/wolves/story/410461.html/|title=adn.com|archive-date=February 13, 2009}}</ref> Some scientists believe that this artificial inflation of game populations is actually detrimental to both caribou and moose populations as well as the ecosystem as a whole.

==== Consumption of offal====
Cadmium levels are high in Finnish moose liver and kidneys, with the result that consumption of these organs from moose more than one year old is prohibited in Finland.<ref>{{cite web |url=http://www.foodqualitynews.com/Food-Alerts/All-clear-for-Finnish-foods |title=All-clear for Finnish foods |date=11 August 2003 |publisher=Food Quality News|access-date=November 6, 2009 |archive-url=https://web.archive.org/web/20091110081823/http://www.foodqualitynews.com/Food-Alerts/All-clear-for-Finnish-foods |archive-date=November 10, 2009 |url-status=live }}</ref> As a result of a study reported in 1988, the Ontario Ministry of Natural Resources recommended against the consumption of moose and deer kidneys and livers.

Cadmium intake has been found to be elevated amongst all consumers of moose meat, though the meat was found to contribute only slightly to the daily cadmium intake. However the consumption of moose liver or kidneys significantly increased cadmium intake, with the study revealing that heavy consumers of moose organs have a relatively narrow safety margin below the levels which would probably cause adverse health effects.<ref>Vahteristo, L., Lyytikäinen, T., Venäläinen, E.

===Vehicle collisions===

The center of mass of a moose is above the hood of most passenger cars. In a collision, the impact crushes the front roof beams and individuals in the front seats.<ref>{{Cite web |url=http://www.vti.se/sv/publikationer/pdf/algdocka-av-gummi-for-krockprov.pdf |title=Archived copy |access-date=October 4, 2011 |archive-url=https://web.archive.org/web/20120311184713/http://www.vti.se/sv/publikationer/pdf/algdocka-av-gummi-for-krockprov.pdf |archive-date=March 11, 2012 |url-status=live }}</ref> Collisions of this type are frequently fatal; seat belts and airbags offer little protection.<ref>[https://web.archive.org/web/20080529203439/http://www.vti.se/nordic/2-04mapp/annosv.html Traffic Management for a Sustainable Environment] Number 2, 2004, of Nordic Road & Transport Research.

Moose warning signs are used on roads in regions where there is a danger of collision with the animal.

In the Canadian province of New Brunswick, collisions between automobiles and moose are frequent enough that all new highways have fences to prevent moose from accessing the road, as has long been done in Finland, Norway, and Sweden. A demonstration project, Highway&nbsp;7 between Fredericton and Saint John, which has one of the highest frequencies of moose collisions in the province, did not have these fences until 2008, although it was and continues to be extremely well signed.<ref>[http://www.gnb.ca/0113/moose/alert-e.asp Moose-Vehicle Collision Information] {{webarchive|url=https://web.archive.org/web/20070114141943/http://www.gnb.ca/0113/moose/alert-e.asp |date=January 14, 2007 }}, New Brunswick Department of Transportation</ref><ref>[http://www.gnb.ca/cnb/news/tran/2008e0411tr.htm More wildlife fencing to be installed on Route 7 in 2008] {{Webarchive|url=https://web.archive.org/web/20110117200940/http://www.gnb.ca/cnb/news/tran/2008e0411tr.htm |date=January 17, 2011 }}, Communications New Brunswick, April 8, 2008</ref> Newfoundland and Labrador recommended that motorists use caution between dusk and dawn because that is when moose are most active and most difficult to see, increasing the risk of collisions.<ref>{{cite web |url=http://www.roads.gov.nl.ca/moose.htm |title=Highway Driving Conditions – Department of Transportation and Works |publisher=www.roads.gov.nl.ca |access-date=November 6, 2009 |archive-url=https://web.archive.org/web/20080513202718/http://www.roads.gov.nl.ca/moose.htm |archive-date=May 13, 2008 }}</ref> Local moose sightings are often reported on radio stations so that motorists can take care while driving in particular areas.

===Domestication===
[[File:Vyborg ElkMonument 006 9848c.jpg|thumb|Sculpture by the Finnish Jussi Mäntynen from 1923. The statue was preserved intact from the Second World War and is located in Vyborg]]
Domestication of moose was investigated in the Soviet Union before World War II. Early experiments were inconclusive, but with the creation of a moose farm at Pechora-Ilych Nature Reserve in 1949, a small-scale moose domestication program was started, involving attempts at selective breeding of animals on the basis of their behavioural characteristics. Since 1963, the program has continued at Kostroma Moose Farm, which had a herd of 33 tame moose as of 2003. Although at this stage the farm is not expected to be a profit-making enterprise, it obtains some income from the sale of moose milk and from visiting tourist groups. Its main value, however, is seen in the opportunities it offers for the research in the physiology and behavior of the moose, as well as in the insights it provides into the general principles of animal domestication.

In Sweden, there was a debate in the late 18th century about the national value of using the moose as a domestic animal. Among other things, the moose was proposed to be used in postal distribution, and there was a suggestion to develop a moose-mounted cavalry. Such proposals remained unimplemented, mainly because the extensive hunting for moose that was deregulated in the 1790s nearly drove it to extinction. While there have been documented cases of individual moose (eg Älgen Stolta) being used for riding and/or pulling carts and sleds, Björklöf concludes no wide-scale usage has occurred outside fairy tales.<ref>Björklöf, Sune. (1995).
