The '''chital''' ('''''Axis axis'''''; {{IPAc-en|tʃ|iː|t|əl}}), also called '''spotted deer''' and '''axis deer''', is a [[deer]] [[species]] native to the [[Indian subcontinent]]. It was first described by [[Johann Christian Polycarp Erxleben]] in 1777. A moderate-sized deer, male chital reach {{cvt|90|cm}} and females {{cvt|70|cm}} at the shoulder. While males weigh {{cvt|70|-|90|kg}}, females weigh around {{cvt|40|-|60|kg}}. It is [[sexually dimorphic]]; males are larger than females, and [[antler]]s are present only on males. The upper parts are golden to rufous, completely covered in white spots. The abdomen, [[Rump (animal)|rump]], throat, insides of legs, ears, and tail are all white. The antlers, three-pronged, are nearly {{cvt|1|m}} long.

==Etymology==
The vernacular name "chital" (pronounced {{IPAc-en|tʃ|iː|t|əl}})<ref>{{Dictionary.com|Chital|access-date=24 December 2019}}</ref> comes from ''cītal'' ({{langx|hi|चीतल}}), derived from the [[Sanskrit Language|Sanskrit]] word ''{{IAST|citrala}}'' (चित्रल), meaning "variegated" or "spotted".<ref>{{cite book |last=Platts |first=J.

===Australia===
The chital was the first species of deer introduced into Australia in the early 1800s. While some of the stock originated from Sri Lanka, the Indian race likely is also represented.<ref>{{cite web |title=Australia's Wild Deer |website=Australian Deer Research Foundation (ADRF) |url=http://adrf.com.au/content/view/35/79/ |access-date=17 February 2016}}</ref><ref>{{cite web |title=Deer in Australia |work=[[Australian Deer Association]] |url=http://www.austdeer.com.au/deer-in-australia/ |archive-url=https://web.archive.org/web/20160220190655/http://www.austdeer.com.au/deer-in-australia/ |access-date=17 February 2016 |archive-date=20 February 2016}}</ref>

===United States===
In the 1860s, chital were introduced to the island of [[Molokai, Hawaii]], as a gift from Hong Kong to [[King Kamehameha V]]. By 2021, there were approximately 50,000 to 70,000 Axis deer on Molokai, as opposed to a human population of 7,500 people. During a drought that extended into 2021, hundreds of the deer died of starvation.<ref>{{cite news |last=Jones |first=Caleb |title=Deer native to India starve to death amid drought in Hawaii |newspaper=[[Associated Press]] |location= |pages= |language= |publisher= |date=9 February 2021 |url=https://apnews.com/article/science-deer-droughts-coronavirus-pandemic-hawaii-ca975acd65b3f30d9296963263af6f0e |access-date=1 October 2023}}</ref>

Chital were introduced to [[Lanai]] island, and soon became plentiful on both islands. Chital were introduced to Maui island in the 1950s to increase hunting opportunities. Because the chital has no natural predators on the Hawaiian islands, the population had been growing 20 to 30% each year, causing serious damage to agriculture and natural areas.<ref>{{cite news |last=McAvoy |first=A. |date=2012 |title=Mystery deer growth pitting hunters against Hawaii |agency=Associated Press |url=https://news.yahoo.com/mystery-deer-growth-pitting-hunters-against-hawaii-173250448.html |access-date=24 May 2012}}</ref> To help control the excess population on Maui, a company called Maui Nui was founded in 2017 to hunt the deer and sell venison.<ref>{{cite magazine|last=Nosowitz |first=D. |title=The Struggle to Contain, and Eat, the Invasive Deer Taking over Hawaii |magazine=[[Modern Farmer (magazine)|Modern Farmer]] |pages= |date=2021 |url=https://modernfarmer.com/2021/05/the-struggle-to-contain-and-eat-the-invasive-deer-taking-over-hawaii/ |access-date=1 October 2023}}</ref> In 2022, the company took 9,526 deer and sold {{cvt|450000|lbs|kg}} of venison.

Releasing them on the [[Hawaii (island)|island of Hawaii]] was planned, but was abandoned after pressure from scientists over damage to landscapes caused by the chital on other islands. In 2012, chital were spotted on the island of Hawaii; wildlife officials think that people had flown them by helicopter and transported them by boat onto the island. In August 2012, a helicopter pilot pleaded guilty to transporting four chital from [[Maui]] to Hawaii.<ref>{{cite news |author=McAvoy, A. |date=2012 |title=Alleged animal smugglers used helicopters to fly sheep to Maui, deer to Big Island |agency=Associated Press |url=https://news.yahoo.com/alleged-animal-smugglers-used-helicopters-fly-sheep-maui-053016426.html |access-date=22 August 2012}}</ref> Hawaii law now prohibits "the intentional possession or interisland transportation or release of wild or feral deer."<ref>{{cite news |title=New law prohibits having or releasing feral deer in Hawaii |work=Honolulu Star-Advertiser |url=http://www.staradvertiser.com/news/breaking/159949735.html?id=159949735 |archive-url=https://web.archive.org/web/20120626141712/http://www.staradvertiser.com/news/breaking/159949735.html?id=159949735 |date=21 June 2012 |access-date=21 June 2012 |archive-date=26 June 2012}}</ref>

Chital of unknown origin were introduced to the islands of [[Brijuni]] in 1911. They also live on [[Rab Island]]. The population on the islands comprised about 200 individuals as of 2010.

There have been sightings of herds of introduced chital in an interandean valley near the municipality of [[Puerto Triunfo]] in [[Antioquia Department]].<ref>{{cite journal |author1=Ramírez-Chaves, H. |author2=Roncancio-Duque, N. |author3=Morales-Martínez, D.M. |year=2023 |title=Más allá de los hipopótamos: evidencia de un venado introducido en Colombia |journal=Revista de la Academia Colombiana de Ciencias Exactas, Físicas y Naturales |volume=47 |issue=185 |pages=882–888 |doi=10.18257/raccefyn.1953 |doi-access=free}}</ref>

==Behaviour and ecology==
Chital are active throughout the day. In the summer, time is spent in rest under shade, and the sun's glare is avoided if the temperature reaches {{Convert|80|F|C}}; activity peaks as dusk approaches. As days grow cooler, foraging begins before sunrise and peaks by early morning. Activity slows down during midday, when the animals rest or loiter about slowly. Foraging recommences by late afternoon and continues till midnight.

When cautiously inspecting its vicinity, the chital stands motionless and listens with rapt attention, facing the potential danger, if any. This stance may be adopted by nearby individuals, as well. As an antipredator measure, chital flee in groups (unlike the hog deer that disperse on alarm); sprints are often followed by hiding in dense [[undergrowth]]. The running chital has its tail raised, exposing the white underparts.<ref name=schaller /> The chital can leap and clear fences as high as {{cvt|1.5|m}} but prefers to dive under them. It stays within {{cvt|300|m}} of cover.<ref name=valerius />

A gregarious animal, the chital forms matriarchal herds comprising an adult female and her offspring of the previous and the present year, which may be associated with individuals of any age and either sex, male herds, and herds of juveniles and mothers.<ref name="ables" /><ref name="wg" /> Small herds are common, though aggregations of as many as 100 individuals have been observed.<ref name="texas" /> Groups are loose and disband frequently, save for the juvenile-mother herd.<ref name="de silva">{{cite journal |last1=De Silva |first1=P.K. |last2=De Silva |first2=M. |year=1993 |title=Population structure and activity rhythm of the spotted deer in Ruhuna National Park, Sri Lanka |journal=Developments in Animal and Veterinary Sciences |issue=26 |pages=285–294}}</ref> Herd membership in [[Texas]] is typically up to 15;<ref name="ables" /> herds can have five to 40 members in India.<ref name="schaller" /><ref name="ap">{{cite journal |last=Srinivasulu |first=C. |year=2001 |title=Chital (''Axis axis'' Erxleben, 1777) herd composition and sex ratio on the Nallamala Hills of Eastern Ghats, Andhra Pradesh, India |journal=Zoos' Print Journal |volume=16 |issue=12 |pages=655–658 |doi=10.11609/jott.zpj.16.12.655-8 |doi-access=free}}</ref> Studies in the [[Nallamala Hills]] ([[Andhra Pradesh]], India) and the [[Western Ghats]] (western coast of India) showed seasonal variation in the [[sex ratio]] of herds; this was attributed to the tendency of females to isolate themselves ahead of parturition.

Predators of chitals include [[Indian wolf|Indian wolves]], [[tiger]]s, [[Asiatic lion]]s, [[leopard]]s, [[Python (genus)|pythons]], [[dhole]]s, [[Indian pariah dog]]s, and [[crocodile]]s. [[Fishing cat]]s, [[jungle cat]]s, [[Vulpes|foxes]], [[golden jackal]]s and [[eagle]]s target juveniles. Males are less vulnerable than females and juveniles.<ref name="valerius" /><ref name="schaller" />

A vocal animal, the chital, akin to the [[North American elk]], gives out bellows and alarm barks.<ref name="texas" /> Its calls are, however, not as strong as those of elk or [[red deer]]; they are mainly coarse bellows or loud growls.<ref name="valerius" /> Bellowing coincides with rutting.<ref name="schaller" /><ref name="Mishra 1987">Mishra, H. and Wemmer, C. 1987.

[[File:Tiger and deers.jpg|thumb|Tiger and chital in Kanha National Park]]
Marking behaviour is pronounced in males. Males have well-developed [[preorbital gland]]s (near the eyes). They stand on their hind legs to reach tall branches and rub the open preorbital glands to deposit their scent there. This posture is also used while foraging. Urine marking is also observed; the smell of urine is typically stronger than that of the deposited scent. Sparring between males begins with the larger male displaying his dominance before the other; this display consists of hissing heading away from the other male with the tail facing him, the nose pointing to the ground, the ears down, the antlers upright, and the upper lip raised. The fur often bristles during the display. The male approaches the other in a slow gait. Males with velvet antlers may hunch over instead of standing erect as the males with hard antlers. The opponents then interlock their horns and push against each other, with the smaller male producing a sound at times which is louder than that produced by [[sambar deer]], but not as much as the barasingha's. The fight terminates with the males stepping backward, or simply leaving and foraging.<ref name="valerius" /> Fights are not generally serious.<ref name="schaller" />

Individuals may occasionally bite one another.<ref name="valerius" /> [[Common myna]]s are often attracted to the chital.<ref name=waring /> An interesting relationship has been observed between herds of chital and troops of the [[northern plains grey langur]]s, a widespread South Asian monkey. Chital benefit from the langurs' eyesight and ability to post a lookout from trees, while the langur benefit from the chital's strong sense of smell, both of which help keep a check on potential danger.<ref name="schaller" /> The chital also benefit from fruits dropped by langurs from trees such as ''[[Terminalia bellirica]]'' and ''[[Phyllanthus emblica]]''.<ref>{{cite journal |last1=Prasad |first1=S. |last2=Chellam |first2=R. |last3=Krishnaswamy |first3=J. |last4=Goyal |first4=S.P. |year=2004 |title=Frugivory of ''Phyllanthus emblica'' at Rajaji National Park, northwest India |journal=Current Science |volume=87 |issue=9 |pages=1188–1190 |url=http://www.iisc.ernet.in/currsci/nov102004/1188.pdf |access-date=22 February 2008 |archive-date=24 September 2015 |archive-url=https://web.archive.org/web/20150924033753/http://www.iisc.ernet.in/currsci/nov102004/1188.pdf}}</ref><ref>{{cite journal |last=Newton |first=P.N. |year=1989 |title=Associations between langur monkeys (''Presbytis entellus'') and chital deer (''Axis axis''): Chance encounters or a mutualism? |journal=Ethology |volume=83 |issue=2 |pages=89–120 |doi=10.1111/j.1439-0310.1989.tb00522.x |bibcode=1989Ethol..83...89N}}</ref> The chital has been observed foraging with sambar deer in the Western Ghats.<ref name=wg />

===Diet===
[[File:Nagjirar ekla harin - Debabrata Ghosh.jpg|thumbnail|right|Chital graze when grasses are available, else they browse.]]
Grazers as well as [[Browsing (herbivory)|browsers]], the chital mainly feed on grasses throughout the year. They prefer young shoots, in the absence of which, tall and coarse grasses are nibbled off at the tips. Browse forms a major portion of the diet only in the winter-October to January-when the grasses, tall or dried up, are no longer palatable. Browse includes herbs, shrubs, foliage, fruits, and [[forb]]s; ''[[Moghania]]'' species are often preferred while browsing. Fruits eaten by chital in the [[Kanha National Park]] ([[Madhya Pradesh]], India) include those of ''[[Ficus]]'' species from January to May, ''[[Cordia myxa]]'' from May to June, and ''[[Syzygium cumini]]'' from June to July. Individuals tend to group together and forage while moving slowly.<ref name=schaller /> Chital are generally silent when grazing together. Males often stand on their hindlegs to reach tall branches. Water holes are visited nearly twice daily, with great caution.<ref name="valerius" /> In the Kanha National Park, [[mineral lick]]s rich in calcium and phosphorus pentoxide were scraped at by the [[incisor]]s. Chital also gnaw bones and fallen antlers for their minerals. Males in velvet indulge in such osteophagia to a greater extent.<ref>{{Cite journal |last=Barrette |first=C. |date=1985 |title=Antler eating and antler growth in wild Axis deer |journal=Mammalia |volume=49 |issue=4 |doi=10.1515/mamm.1985.49.4.491 |s2cid=85046773}}</ref> Chital in the [[Sunderbans]] may be [[omnivore]]s; remains of [[Christmas Island red crab|red crabs]] have been found in the [[rumen]] of individuals.<ref name=schaller />

{{anchor|Breeding}}
<!-- [[Sexual maturity]] is reached within ???? -->Breeding takes place throughout the year, with peaks that vary geographically. [[Sperm]] is produced year-round, though testosterone levels register a fall during the development of the antlers. Females have regular oestrus cycles, each lasting three weeks. The female can conceive again two weeks to four months after the birth. Males sporting hard antlers are dominant over those in velvet or those without antlers, irrespective of their size. Courtship is based on tending bonds. A [[Rut (mammalian reproduction)|rutting]] male fasts during the mating season and follows and guards a female in oestrus. The pair does several bouts of chasing and mutual licking before copulation.<ref name=valerius>{{cite book |last=Geist |first=V. |date=1998 |title=Deer of the World: their Evolution, Behaviour and Ecology |edition=1st |publisher=Stackpole Books |location=Mechanicsburg, Pennsylvania |url={{Google Books |plainurl=yes |id=bcWZX-IMEVkC |page=58}} |pages=58–73 |isbn=978-0-8117-0496-0}}</ref>

The newborn is hidden for a week after birth, a period much shorter than most other deer. The mother-fawn bond is not very strong, as the two get separated often, though they can reunite easily as the herds are cohesive. If the fawn dies, the mother can breed once again so as to give birth twice that year. The males continue their growth till seven to eight years. The average lifespan in captivity is nearly 22 years. The longevity in the wild, however, is merely five to ten years.<ref name=valerius /><ref name=schaller />

The chital is found in large numbers in dense deciduous or semi-evergreen forests and open grasslands.<ref name="schaller">{{cite book |last=Schaller |first=G.B. |date=1984 |title=The Deer and the Tiger: A Study of Wildlife in India |edition=Midway reprinted |publisher=University of Chicago Press |location=Chicago |isbn=978-0-226-73631-0}}</ref> The highest numbers of chital are found in the forests of India, where they feed upon tall grass and shrubs. Chital have been also spotted in [[Phibsoo Wildlife Sanctuary]] in Bhutan, which has the only remaining natural sal (''[[Shorea robusta]]'') forest in the country. They do not occur at high altitudes, where they are usually replaced by other species such as the sambar deer. They also prefer heavy forest cover for shade and avoid direct sunlight.<ref name=valerius/>

==Conservation status==
The chital is listed on the [[IUCN Red List]] as [[least concern]] "because it occurs over a very wide range within which there are many large populations".<ref name=iucn /> Currently, no range-wide threats to chitals are present, and they live in many protected areas. However, population densities are below ecological carrying capacity in many places due to hunting and competition with domestic livestock. Hunting for the deer's meat has caused substantial declines and local extinctions.<ref name=iucn /> The axis deer is protected under Schedule III of the Indian Wildlife Protection Act (1972)<ref name=sankar /> and under the Wildlife (Preservation) (Amendment) Act, 1974 of Bangladesh.<ref name=iucn /> Two primary reasons for its good conservation status are its legal protection as a species and a network of functioning protected areas.<ref name=iucn />

The chital has been introduced to the [[Andaman Islands]], Argentina, Australia, Brazil, Chile, Mexico, Paraguay, Uruguay, Alabama, [[Point Reyes National Seashore]] in California,{{citation needed|date=July 2024}} Florida, Hawaii, Mississippi, and Texas in the United States.<ref name=iucn /> In 1911, it was brought to the acclimatisation station for European zoos at [[Brijuni Islands]] in Croatia; it was introduced to [[Rab (island)|Rab]] and [[Dugi Otok]] islands in 1974 and 2012, respectively.<ref>{{cite journal |author1=Šprem, N. |author2=Stipoljev, S. |author3=Ugarković, D. |author4=Buzan, E. |year=2021 |title=First genetic analysis of introduced axis deer from Croatia |journal=Mammalian Biology |volume=101 |issue=6 |pages=1121–1125 |doi=10.1007/s42991-021-00164-9 |url=https://www.vsvo.si/wp-content/uploads/2021/08/Sprem2021_Article_FirstGeneticAnalysisOfIntroduc.pdf}}</ref>

With effect from 2 August 2022, the European Union added the chital to the list of invasive alien species and banned its import.<ref>{{Cite web |date=2022 |title=Commission Implementing Regulation (EU) 2022/1203 of 12 July 2022 |url=https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:32022R1203&from=CS#ntr2-L_2022186EN.01001001-E0002 |access-date=2022-07-29 |website=Official Journal of the European Union}}</ref>
