Acoustic (that is, sound) signals are omni directional (i.e. they travel in all directions) and can be broadcast to a large audience including intended and unintended listeners, and those in view and hidden from view. Being short-lived and deliberate, acoustic signals are useful for giving information about an immediate situation, rather than about a constant state. Through reflection, refraction and absorption, acoustic signals are degraded by the environment in ways that are often very much greater for high frequency sounds than for low frequency sounds. Elephants are specialists in the production of low frequency sound and in the use of long-distance communication. Check out some good examples on acoustic communication by elephants in article "What Elephant Calls Mean: A User's Guide" published by National Geographic in 2014, based on the work of ElephantVoices.

The range of sounds elephants produce

Elephants produce a broad range of sounds from very low frequency rumbles to higher frequency snorts, barks, roars, cries and other idiosyncratic calls. Asian elephants also produce chirps. The most frequently used category of calls, at least for African elephants, is the very low frequency rumble. You can search for, listen to and read about numerous sounds through in the Multimedia

"To inspire wonder in the intelligence, complexity and voices of elephants,
and to secure a kinder future for them."

Our goals are to advance the study of elephant cognition, communication and social behavior, and to promote the scientifically sound and ethical management and care of elephants. We accomplish these through research, conservation, advocacy and the sharing of knowledge.

Like all highly social mammals elephants have a well-developed system of communication that makes use of all of their senses - hearing, smell, vision and touch - including an exceptional ability to detect vibrations.

Acoustic communication takes a look at sound production and hearing in elephants; chemical communication explains how elephants use various secretions and their acute sense of smell to communicate; visual communication looks at how elephants make use of postures and displays and their sense of sight in communication; tactile communication describes how elephants make use of their sense of touch to communicate.

At one end of the spectrum elephants communicate by rubbing their bodies against one another, at the other end they may respond by moving toward the sounds of other elephants calling, perhaps 10 kilometers away. They convey information about their physiological (e.g. sexual/hormonal, body condition, identity) and emotional state (e.g. whether they are fearful, playful, joyful, angry, excited) as well as communicating specific "statements" about their intentions or desires. In this section we look at how elephants use the different pathways of communication and the actual mechanics of communicating.

Similar to the harmonic-play-trumpet, but exhibiting a more prolonged and resolute quality is a trumpet that is associated with Mock-Charging behavior.

Cavorting elephants often chase other species in their environment (such as rabbits, hyenas, wildebeests, monkeys) during which they trumpet loudly.

We term trumpets associated with this form of play, mock-charge-play-trumpets. These trumpets are significantly longer in duration than harmonic-play-trumpets.

Context of Interactions

Elephants are extremely tactile animals. They purposefully touch one another using their trunk, ears, tusks, feet, tail, and even their entire body. Tactile interactions between elephants occur during a broad range of contexts including aggressive, defensive, affiliative, sexual, playful, care-taking and exploratory behavior.

Depending upon how their tusks are employed, elephants may use them to poke another aggressively, to gently lift a baby from a mud wallow, or to express solidarity during a greeting ceremony.

Elephants often use their ears to rub against another affectionately or in play, or their tails to swat another with force or to gently check for the presence of a calf.

An elephant's trunk may be used to caress, reassure or assist a calf, to explore the genitals, mouth or temporal glands of a family member, to touch or explore the body of a dead elephant, to touch or push another in play. In more aggressive or defensive contexts an elephant may use its trunk to slap or to block, or to reach out to another for reassurance when facing a predator. In sexual contexts elephants use their trunks to explore, to test or to control the movements of another.

Elephants use

ElephantVoices is working on a major initiative to document the repertoire of African savannah elephant behavior (Loxodonta africana). The Elephant Ethogram will represent a unique and comprehensive source of information about elephant behaviour and communication, based on ElephantVoices' decades of behavioural study, our multimedia photographic and acoustic collections, as well as footage collected during the filming of documentaries from the Maasai Mara, Kenya, and Gorongosa National Park, Mozambique. The Elephant Ethogram will describe and preserve the gestural and acoustic "language" and behaviour of a species whose way of life, and very existence, is threatened by human greed and expansion.

The first version of The Elephant Ethogram will be launched on ElephantVoices.org during first half of 2020. 

Purpose & Objectives

The Elephant Ethogram intends to document in unique, user-friendly and fully searchable databases, the complex and diverse communication and behavior of African elephants for scientists and others to study, compare and share. As a repository of exemplars of elephant behaviour, The Elephant Ethogram aims to:

• preserve the gestural and acoustic repertoire, or "language," of African savannah elephants;
• be a valuable resource and reference for scientific study;
• be a repository of rare elephant behaviors and those evolving through social learning in response to rapidly increasing anthropogenic
