Researchers Uncover Complex Elephant Greetings in Zimbabwe Reserve

Researchers at the University of Vienna studied African savannah elephants in Zimbabwe's Jafuta Reserve, revealing diverse greeting behaviors involving visual, acoustic, and tactile gestures. The study found differences in greeting behaviors between female and male elephants, with females engaging in elaborate ceremonies to strengthen social bonds.

Researchers Uncover Complex Elephant Greetings in Zimbabwe Reserve

A recent study by researchers at the University of Vienna has shed new light on the intricate greeting behaviors of African savannah elephants in Zimbabwe's Jafuta Reserve. The findings, published in the journal Communications Biology, reveal that elephants employ a diverse array of visual, acoustic, and tactile gestures during greetings, which vary based on factors such as sex and social bonds.

Why this matters: Understanding the complex social behaviors of elephants can provide valuable insights into their conservation and management, ultimately informing efforts to protect these majestic creatures and their habitats. Furthermore, studying animal communication can also shed light on the evolution of human social behavior and language.

Led by cognitive and behavioral biologist Vesta Eleuteri, the research team observed nine semi-captive elephants, four females and five males, in their natural environment during the day and in stables at night. The study built upon previous research on elephant greeting behavior and provides fresh insights into the complexity of their social interactions.

The researchers discovered that elephants utilize around 20 different gesture types during greetings, combining them with specific call types such as rumbles, roars, and trumpets. Smell also plays a crucial role in these interactions, involving urination, defecation, and secretions from the temporal gland, a unique elephant gland located midway between the eye and ear that produces a substance called temporin containing chemical information about an elephant's identity, emotional state, and sexual state.

Remarkably, the study found that elephants are aware of others' visual perspectives and adjust their greeting gestures accordingly. "We found that they select these visual, acoustic and tactile gestures by taking into account whether their greeting partner was looking at them or not, suggesting they're aware of others' visual perspectives," explained Eleuteri.

The researchers also discovered significant differences in greeting behaviors between female and male elephants. Females, who form strong social bonds known as "bond groups," engage in elaborate greeting ceremonies to strengthen these connections. In contrast, males have weaker social bonds, and their greetings may serve to ease potential hostile interactions or "risky reunions."

"Elephants live in a so-called 'fission-fusion' society, where they often separate and reunite, meeting after hours, days or months apart," noted Eleuteri. The study highlights the importance of chemical information in elephant communication, with urine and feces containing crucial details about an individual's identity, reproductive state, and emotional state. "Elephants might defecate or urinate during greetings to release this important information. Another option is that they do this due to the excitement of seeing each other," Eleuteri added.

The greeting behavior of the female elephants in the study closely matched that of wild elephants, while the male elephants' behavior differed from their wild counterparts. This groundbreaking research provides a fascinating window into the complex social lives of African savannah elephants and underscores the importance of understanding and preserving these magnificent creatures and their habitats.

Key Takeaways
