Do Animals Understand Each Other’s Communication?
Animals hear other species communicating around them every day. But do they truly understand what those other species are “saying”?
Every year, scientists uncover more mysteries about how animals communicate. From elephants flapping their ears in greeting to sperm whales adjusting their clicking sounds depending on conversation context, and even naked mole rats having distinct vocal dialects—it’s clear that the animal world is far from silent.
With such rich communication methods, can one species learn another’s “language”? The answer is yes—some animals can not only understand but also use signals from other species for their own benefit.
Do Animals Have ‘Languages’?
Before diving into how animals learn to communicate across species, it’s important to clarify: animals do not have “language” in the human sense.
“Language is a unique communication system of humans,” explains Professor Simon W. Townsend from the University of Zurich. When studying animal communication, scientists avoid human-centric definitions and instead analyze whether specific sounds or signals convey meaning.
Although animals do not possess a structured language like humans, many species can perceive and interpret signals from others.
Birds Understanding Each Other on Migration Journeys
One of the most fascinating studies of cross-species communication comes from observing migrating birds. Scientists previously believed that songbirds migrated alone, but new research shows they may understand warning calls from other species along their journey.
Dr. Benjamin Van Doren, a natural resource expert at the University of Illinois Urbana-Champaign, analyzed bird calls using acoustic data. He found that solitary songbirds tend to gather around others and may use their alarm calls to navigate or avoid danger.
“We look for patterns in vocalizations to see if there is cross-species communication,” Van Doren explains. However, scientists still struggle to decode precisely what these birds are “saying” to each other.
The Fork-Tailed Drongo: Nature’s Master Deceiver
Understanding another species’ calls is one thing, but mimicking them for personal gain is even more remarkable. That is exactly what the fork-tailed drongo (Dicrurus adsimilis), a small African bird, does.
Drongos are notorious thieves in the animal kingdom. They follow meerkat groups, waiting for the right moment to steal food. Their trick? They mimic predator alarm calls, causing meerkats to panic and flee, leaving their food behind.
However, this strategy has limits. If meerkats detect deception, they will ignore future alarms. Drongos then adapt by imitating the warning calls of meerkats or other bird species to maintain the effectiveness of their deception.
Dr. Thomas Flower from Capilano University, who has studied drongos in the wild, states:
“They not only understand the vocalizations of other species but also know when to switch signals to keep fooling their targets. This is a remarkable example of animals learning from others to their advantage.”
Do Drongos Know They Are Deceiving?
A crucial question arises: Do drongos consciously know they are deceiving, or are they simply responding to learned patterns?
According to Flower, proving intentional deception in animals is extremely difficult. His research suggests that young drongos initially imitate random sounds and refine their skills through trial and error. This learning process is similar to how human children mimic words before fully grasping their meaning.
“There’s still much to uncover about how drongos develop these strategies,” says Flower. “But their ability to flexibly use signals from other species is undeniably impressive.”
The Ongoing Mystery of Cross-Species Communication
The ability to understand and use signals from different species provides survival advantages, whether it’s avoiding predators, locating food, or maintaining social bonds.
Despite remarkable discoveries, the neurological mechanisms behind this skill remain largely unknown. Do animals truly comprehend the meaning of these signals, or are they simply responding to repetitive stimuli?
These studies not only deepen our understanding of the natural world but also raise an intriguing question: Could humans one day establish meaningful two-way communication with animals? Unlocking this mystery might lead to a revolutionary shift in how we interact with the animal kingdom.
