How Elephants Communicate: The Science of Infrasound
Elephant communication is one of the most sophisticated in the animal kingdom, operating across multiple channels simultaneously. The most scientifically significant discovery of recent decades — made by researcher Katy Payne in the 1980s — is that elephants produce and receive infrasonic vocalizations at frequencies below the range of human hearing (below 20 hertz). These infrasonic rumbles travel through both the air and the ground for distances of up to 10 kilometers, allowing elephant family groups to coordinate movements and maintain contact across the large distances of the savannah ecosystem. Safari travelers who are paying attention can observe the behavioral correlate of infrasonic communication without hearing the call itself: a family group that suddenly orients in the same direction, ears spread and feet slightly apart in a posture of intense listening, is receiving infrasonic information from a distance. The response — the group moving purposefully in a new direction, or a matriarch vocalizing back in the low rumble that is just audible to humans as a felt vibration rather than a heard sound — completes the observable behavioral sequence of a conversation whose acoustic content is inaudible to the human observer.
The audible components of elephant communication — the full range of trumpets, rumbles, growls, and screams that safari travelers hear directly — serve different functions from the infrasonic communication. Trumpeting is generally a display of alarm, excitement, or aggression visible to nearby observers. The contact rumble — a low, continuous vocalization exchanged between family members at short range — is the conversational glue of family group cohesion during movement and feeding. The musth rumble — produced by adult males in musth, the periodic hormonal state of elevated testosterone that makes bull elephants aggressive and sexually active — advertises the bull’s status to both competing males and receptive females across long distances. Guides who know these vocalizations can narrate the acoustic content of an elephant encounter in real time, transforming what appears to be a silent group of grazing animals into a socially complex, communicating community.
The Matriarch: Memory, Leadership, and Navigation
The African elephant’s family group is led by the oldest female — the matriarch — whose experience, memory, and social knowledge determine the group’s survival in ways that have been rigorously documented by the Amboseli Elephant Research Project and the Serengeti’s elephant study groups. The matriarch’s memory for water sources — critical in dry years when the group’s survival depends on knowing where the last seasonal pool still holds water at the end of the dry season — extends over decades and across the entire home range of the family. Research has documented that family groups led by older, more experienced matriarchs survive drought years at higher rates than groups led by younger females with less experiential memory, and that the matriarch’s social knowledge — recognizing the calls of dozens of other families, distinguishing friend from rival from stranger by voice alone — is a survival asset that accumulates with age.
The matriarch’s leadership during a predator encounter is immediately observable on safari. When a family group encounters a lion or predator threat, all eyes turn to the matriarch — her behavioral response determines whether the group charges, retreats, or investigates. An experienced matriarch who recognizes a lion as a non-threatening individual (one she has encountered many times without incident) will lead the group past it with no more than a warning glare. A young matriarch with less predator experience may lead a full-group charge at the same lion, producing the dramatic defensive display — ears spread, trunk raised, ground-stamping — that is the most spectacular elephant behavioral performance a game drive can witness.
Bull Elephant Behavior: Musth, Hierarchy, and Independence
Adult male elephants live independently from the family groups for most of their adult lives, associating with females only during musth when the hormonal drive to seek out receptive females overrides the usual bull-family separation. Musth in adult bulls is signaled by a combination of visible and olfactory cues: the temporal gland secretion (a dark, oily discharge that runs down the side of the face from the temporal gland located between the eye and ear), the constant dribbling of urine (which deposits testosterone-laden scent along the bull’s route), and the distinctive musth rumble vocalization. A bull in musth is significantly more aggressive than a non-musth bull — approach distances from game drive vehicles should be greater than usual, and experienced guides read a bull’s musth status before deciding how closely to approach.
The male hierarchy outside musth is organized by age, size, and experience in a set of relationships worked out through ritualized sparring contests that young bulls practice from an early age. Sparring bulls — interlocking tusks and pushing against each other’s heads and necks in a wrestling match that is clearly play rather than combat in most cases — are a frequently observed behavioral scene in areas with high bull elephant density. Tarangire and Amboseli are both excellent for observing male hierarchy dynamics because these parks have high bull populations relative to their overall herd sizes.
Elephant Memory and Grief: What Research Has Revealed
The Amboseli research has documented two behavioral phenomena in elephants that have entered popular awareness as evidence of complex emotional life: the treatment of elephant bones and skulls, and the behavioral changes associated with the death of a family member. Elephants show distinctive behavior around the remains of deceased elephants — touching bones with the tip of the trunk, carrying tusks for short distances, and returning to the site of a death on multiple occasions over years — that researchers describe as bone investigation behavior. Whether this constitutes grief or memory in a human-relevant sense is scientifically debated, but the behavior itself is well-documented and is observable in the field when an elephant family passes the remains of a dead individual.
Best Destinations for Elephant Behavioral Observation in 2027
The best East African destinations for serious elephant behavioral observation are Amboseli (for the researched family groups, the Kilimanjaro backdrop, and the permanent swamp habitat that concentrates family activity), Tarangire in the dry season (for the largest dry-season aggregations and the baobab landscape), and the Maasai Mara conservancies (for year-round elephant families in the riverine woodland). The Serengeti’s elephant population is more dispersed and less intensively studied than Amboseli’s, but the central Seronera area has resident family groups that are consistently present.

Elephant watching in East Africa rewards time and patience above all other techniques. The traveler who spends an hour with a single family group at a waterhole — watching the arrival of different family members, the greeting ceremonies between individuals who have been separated, the calf nursing and play sequences, and the matriarch’s navigation decisions as the group moves off — will accumulate more genuine behavioral understanding from that single hour than a traveler who drives past a dozen different elephant sightings in the same time. In East Africa’s best elephant destinations, the time investment is always worth it.
The best elephant behavioral observations in East Africa reward the patient traveler who is willing to linger at a waterhole or family group encounter long after other vehicles have moved on.
