Musth
Imagine a profound, temporary transformation that turns the calmest giant into an unpredictable force of nature. This is musth, a periodic phenomenon in male elephants marked by extreme aggression and an astounding surge in reproductive hormones. Though ancient cultures observed it for millennia, scientists are still unraveling the complex biological and social factors that drive this powerful state, offering crucial insights into elephant welfare and conservation. Musth is a temporary, hormonally-driven state in bull elephants characterized by extreme aggression and an astonishing increase in testosterone levels. Physical signs like tar-like secretions and specific vocalizations signal a bull's musth, influencing both attraction from females and avoidance from other males. Disruptions to natural elephant social structures, particularly the absence of older males, can lead to aberrant and dangerous musth behaviors in younger bulls.

The Elephant's Frenzy
What is Musth?
The word itself, 'musth,' hints at the condition's intensity. It comes from Urdu, meaning 'intoxication,' and in Persian, it literally translates to 'intoxicated.' It's an apt description for a state that drastically alters an elephant's demeanor.
Musth is a periodic condition in bull (male) elephants, characterized by profoundly aggressive behavior and an accompanying surge in reproductive hormones. It's a dramatic, temporary shift that makes these magnificent creatures incredibly dangerous, even to their own kind.
A History of Observation
For at least 3,000 years, ancient cultures in Asia documented musth, noting its terrifying power. References can be found in texts like the Rigveda, dating back to 1500–1000 B.C., which described this intense period in Asian elephants.
However, it wasn't until the late 20th century, specifically 1981, that musth was scientifically recognized and described in African elephants. This discovery highlighted that this powerful phenomenon is a universal characteristic across elephant species.
The scientific breakthrough for African elephants came largely thanks to researchers Joyce Poole and Cynthia Moss in Kenya's Amboseli National Park. Poole meticulously documented the heightened reproductive activity and aggression, along with the physical and behavioral changes, finally solidifying our understanding of musth in these colossal animals.
Intriguingly, evidence suggests that musth wasn't exclusive to modern elephants. Testosterone histories from mammoth tusks, and behavioral patterns in extinct proboscideans like gomphotheres and mastodons, indicate similar musth-like behaviors may have occurred in these ancient relatives.
Distinguishing Musth from Rut
It's important not to confuse musth with the 'rut' observed in many other mammals. While both are related to reproduction, musth in elephants often takes place in winter, independent of any seasonal estrus cycle in female elephants. This highlights its unique biological timing.
Physical Hallmarks of Musth
One of the most striking physical signs of musth is a thick, tar-like secretion called temporin. This substance oozes from the temporal glands, located on the sides of the elephant's head, leaving dark streaks that are unmistakable indicators of the musth state.
Temporin isn't just a simple discharge; it's a complex chemical cocktail. It contains proteins, lipids, phenols, cresols, and even sesquiterpenes like farnesol. Additionally, urine collected from musth elephants contains elevated levels of highly odorous ketones and aldehydes—all contributing to a powerful chemical signal.
The underlying driver of this transformation is a monumental surge in hormones. Testosterone levels in an elephant in musth average an astounding 60 times greater than at other times. In some individuals, this increase can be as much as 140 times, explaining the dramatic behavioral changes.

Wild bulls in musth also produce a characteristic low, pulsating 'musth rumble' — a sound that can travel for miles. This rumble serves a dual purpose: it attracts receptive females while simultaneously prompting silent avoidance behavior from other bulls and non-receptive females, clearly advertising the bull's heightened, dangerous state.
The aggression during musth is legendary and extremely dangerous. Bull elephants in musth have been known to kill keepers, livestock, other species, and even other elephants, sometimes inadvertently during what might be called 'herd infighting.' Their power, combined with their hormonal frenzy, makes them incredibly formidable.
The 'Rogue Elephant' Phenomenon
A particularly tragic example of musth's destructive potential occurred in the 1990s in South African national parks. Young bull elephants, exhibiting aberrant musth behavior, inexplicably killed 63 rhinoceroses — a devastating loss for already endangered species.
Scientists linked these killings to a profound disruption in the elephants' social structure. These young bulls had been traumatized by witnessing their breeding herds culled due to overcrowding, surviving without the guidance of older, experienced males.
The absence of older males, who naturally inhibit musth in younger, smaller bulls, meant these adolescents entered musth prematurely. This 'warped behavior' was akin to post-traumatic stress disorder, showing how deeply social and emotional attachments impact these intelligent creatures.
The solution, proposed by ranger Gus van Dyk, was to reintroduce older male elephants into these parks. This brilliant intervention successfully halted the rhino killings, demonstrating the crucial role of social hierarchy and experienced elders in maintaining healthy elephant behavior.
Managing Musth in Captivity
For domesticated Asian elephants in Sri Lanka and India, traditional management of musth often involves isolating the bull, tying it to a strong tree, and restricting food and water for about a week. This harsh regimen is believed to shorten the duration of the musth period.
Modern zoos and wildlife facilities managing adult male elephants require purpose-built, incredibly strong enclosures to safely isolate bulls during musth. Sedatives, such as xylazine, are sometimes employed to help manage their extreme agitation and aggression, ensuring both animal and human safety.
Musth in Culture and Literature
Musth's dramatic nature has inspired countless references in culture and literature for millennia. Ancient Indian texts, like the Ramayana and Matanga Lila, describe its power, associating it with attributes such as excitement, wrath, and fearlessness.
Later literary works also feature musth as a central plot device or vivid descriptor. Jules Verne's 'Around the World in Eighty Days' mentions attempts to induce musth for combat, while George Orwell's 'Shooting an Elephant' famously depicts the tragic consequences of a musth rampage.
Even James Bond novels, like Ian Fleming's 'The Man With the Golden Gun,' incorporate musth to explain a villain's backstory. More recently, the Tamil movie 'Kumki' portrays a trained elephant entering musth during a confrontation with wild elephants, highlighting its unpredictable and powerful role in their lives.

Musth or must is a periodic condition in bull (male) elephants characterized by aggressive behavior and accompanied by a large rise in reproductive hormones. It has been known in Asian elephants for 3,000 years but was only described in African elephants in 1981. Evidence indicates that similar behaviour occurred in extinct proboscideans like gomphotheres and mastodons.
Elephants often discharge a thick, tar-like secretion called temporin from the temporal gland during musth. Behavioral management for captive bull elephants in musth includes physical restraint and a starvation diet for several days to a week.
Etymology
Musth
Musth comes from an Urdu term for intoxication; in Persian it means lit. 'intoxicated'.
Biology
Musth
Musth has been known in Asian elephants for 3000 years (described in the Rigveda 1500–1000 B.C.) but was recognized in African elephants only in the late twentieth century.
In 1975, scientists Joyce Poole and Cynthia Moss were working in Amboseli National Park, Kenya. Poole noticed a period of heightened reproductive activity and aggression in male African elephants. She began documenting and describing the physical and behavioral characteristics and temporal (time-related) dynamics among individual males. This led to scientifically identifying musth in African elephants.

Musth is also suggested to have occurred in mammoths, given the testosterone histories from their tusks. Musth-like behaviour is also suggested to have occurred in South American gomphotheres and North American mastodons.
Musth differs from rut in that musth most often takes place in winter, whereas the female elephant's estrus cycle is not seasonally linked.
Physical characteristics
Musth
Elephants in musth often discharge a thick tar-like secretion called temporin from the temporal gland located on the temporal sides of the head. Temporin contains proteins, lipids (including cholesterol), phenol and 4-methyl phenol, cresols and sesquiterpenes (notably farnesol and its derivatives). Secretions and urine collected from zoo elephants have been shown to contain elevated levels of various highly odorous ketones and aldehydes.
Testosterone levels in an elephant in musth average 60 times greater than in the same elephant at other times, and in some individuals can increase by as much as 140 times.
Behavioral characteristics
Musth
Musth is believed to be linked to sexual arousal or establishing dominance. Wild bulls in musth often produce a characteristic low, pulsating rumbling noise known as "musth rumble" that other elephants can hear from miles away. The rumble has been shown to prompt not only attraction in the form of reply vocalizations from cows in heat, but also silent avoidance behavior from other bulls, particularly juveniles and non-receptive females, suggesting an evolutionary benefit to advertising the musth state.
Bull elephants in musth, especially but not only in the wild, are extremely dangerous and have killed keepers/mahouts, livestock, other species, and other bull elephants, female elephants, and calves (the last usually inadvertently or accidentally in what is often called "herd infighting").
During the 1990s, young bull rogue elephants killed 63 rhinos of both sexes (58 endangered white rhinos and 5 rare black rhinos) in two South African national parks (Hluhluwe–Imfolozi and Pilanesberg). This was ultimately attributed to an aberrant form of musth. After being rebuffed by older female elephants, the young bulls went after rhinos, killing them. Three young elephant bulls were shot, temporarily ending the killings. Some scientists opined that this was an example of young male elephants permanently changed by the trauma of witnessing their breeding herds culled due to overcrowding in other South African parks. These young bulls had been spared due to their age and size, although herd culls are properly done in entirety, i.e., leaving no survivors to suffer the equivalents of PTSD, survivor guilt, and other disorders or traumas later in life which could then create or exacerbate human-elephant conflicts or other forms of violence, according to Ron Thomson, a late 20th-century Zimbabwe game warden and Parks Board veteran. South African ecologist and ranger Gus van Dyk, who thought of the idea of reintroducing older males into Pilanesberg to prevent younger males from entering musth, noted that no further rhinoceros killings were observed.
In the absence of older males, whose presence inhibits musth in smaller younger bulls, these adolescent bulls had reached puberty (musth) prematurely, which reduced their control and resulted in the "warped behavior of animals who have lost their elders, and who are now flailing in a diminished, disarranged world." It is established that functionally important decision-making abilities may be significantly altered by disruption of the natural structure of kin-based social relationships and that violent disruption "appears capable of driving aberrant behaviours in social animals that are akin to the post-traumatic stress disorder experienced by humans following extremely traumatic events" due to the pachyderms' intelligence, strong emotional family attachments, and prodigious memories. Another interrelated but more generalized theory of why the young elephants went wild was that, owing to culls and herd fragmentation, there were no older elephants to teach and discipline them.
Management

In Sri Lanka and India, domesticated Asian elephants in musth are traditionally tied to a strong tree and denied food and water for a week or so which shortens the duration of the musth, typically to five to eight days. Sedatives, like xylazine, are also sometimes used. Zoos keeping adult male elephants need strong, purpose-built enclosures to isolate males during their musth.
Cultural depictions
Musth
• Valmiki, in Sundara Kanda of the Ramayana (7th to 4th centuries BCE), made reference to the Mahendra mountain shedding water like an elephant's rut juice upon being pressed by Hanuman. • In the Matanga Lila (300 BCE to 300 CE) musth is described: "Excitement, swiftness, odor, love passion, complete florescence of the body, wrath, prowess, and fearlessness are declared to be the eight excellences of musth." • Sangam poetry (300 BCE to 300 CE) describes musth. Kummatoor Kannanaar in Pathitrupatthu 12 describes it as follows:
It was sweet to hear of your victories and fame and I came here desiring to see you. I came with my big family, passing few mountains where noble, young male elephants with coarse hair and swaying walks have musth flowing from their cheek glands and elephant mothers with calves wave wild jasmine twigs, chasing striped bees that swarm on the sweet musth.
• References to elephants in musth (whose temporin secretion is often referred to as "ichor") are for example in the Raghuvaṃśa (4th–5th century CE), where Kalidasa wrote that the king's elephants drip ichor in seven streams to match the scent put forth by the seven-leaved 'sapta-cchada' (= "seven-leaf") tree (perhaps Alstonia scholaris). • In Jules Verne's Around the World in Eighty Days (1872), Phileas Fogg buys an elephant which was being fed sugar and butter so it would go into musth for combat purposes; however, the animal had been on this regimen for only a relatively short time so the condition had not yet presented. • Shooting an Elephant is an essay by George Orwell written in 1936, in which he describes how an elephant in Burma had an attack of musth and killed an Indian, which in turn led to the narrator shooting the elephant. • In his James Bond novel The Man With the Golden Gun (1965), Ian Fleming wrote that the villain Francisco Scaramanga was driven to become a cold-blooded assassin after authorities shot an elephant that he had ridden in his circus act because the elephant went on a rampage while in musth. • In Barry B. Longyear's 1982 novel Elephant Song, the survivors of the circus starship City of Baraboo have to face the fact that because of the circus rule that male elephants cannot troupe with the show because they might go into musth with no warning, the elephants who survived to land on Momus are doomed to extinction. • The Tamil movie Kumki (2012), which revolves around a mahout and his trained elephant, shows the elephant in musth toward the climax. Captive elephants are trained either for duties in temples and cultural festivals or as kumki elephants, which confront wild elephants and prevent them from entering villages. Elephants trained for temple duties are of a gentle nature and cannot face wild elephants. In the movie, a tribal village wants to hire a kumki elephant to chase away wild elephants that enter the village every harvest season. The mahout, who needs money, takes his temple-trained elephant to do the job in the vain hope that wild elephants will not enter. But wild elephants start attacking the village on the harvest day. The temple-trained elephant enters musth and thus fights with the wild elephants, killing the most notorious among the herd but dying from injuries sustained during the fight.
