What if parrots are more like us than we ever imagined? Scientists have discovered that budgerigars—a species of small, colorful parrots—use a brain system strikingly similar to humans when they “talk.” This groundbreaking finding, reported in Nature, suggests that these chatty birds may hold the key to unlocking how speech works in the human brain—and could even help us understand speech disorders.
Humans aren’t the only species with impressive vocal skills. Parrots, known for their ability to mimic speech, may produce sounds using brain mechanisms much like our own. Until now, no other animal was known to have language-producing brain regions that resemble those in humans. But a team of researchers from NYU Langone Health, led by neuroscientist Michael Long, has uncovered a surprising connection between the way budgerigars (commonly called budgies) and humans create speech.
These small parrots, with their bright feathers and playful nature, are not just adorable—they are also incredibly social and vocal, making them perfect for studying how communication works in the brain.
Long and his colleague Zetian Yang observed the brain activity of four budgies while they chirped and warbled. They found that a specific brain region—the anterior arcopallium—is responsible for controlling their vocal sounds. This part of the brain functions much like a “vocal keyboard,” allowing the birds to produce a wide variety of sounds, from soft vowels to sharp consonants.
“The organization of these neurons’ activity is pretty simple,” says Long. Just as a pianist plays notes on a keyboard to create music, budgies “play” their brain circuits to produce speech-like sounds. This flexible system mirrors how human brains work when forming speech—suggesting that parrots and humans may have developed similar solutions for communicating through sound.
The research team believes this could be a clear example of convergent evolution, where different species independently evolve similar traits to solve the same problem. “You have humans that have developed this kind of neural mechanism for speech, and these parrots have developed a kind of similar mechanism,” Long explains.
Using advanced neural tracking methods, the researchers monitored individual nerve cells while the birds vocalized. Each sound the budgies made—whether a high-pitched chirp or a low warble—was linked to specific patterns of brain activity. By carefully mapping these signals, the scientists could see how the parrots’ brains work in real time to produce complex sounds.
This breakthrough could change how we study speech disorders in humans. Since the budgies’ brain systems resemble ours but are simpler, they may become valuable models for understanding what happens when human speech systems go wrong.
Understanding how birds produce speech-like sounds isn’t just fascinating—it could lead to new treatments for communication disorders in humans. By studying these small parrots, scientists may unlock deeper insights into speech problems like aphasia (the inability to speak or understand language) and other vocal impairments.
But the research raises an even more intriguing question: What are these parrots saying? Long and his team are now using machine learning to translate the meaning behind budgie vocalizations. Could their conversations be as complex as ours?
“This is the first nonhuman animal in which that has been shown,” says Michael Long, emphasizing the uniqueness of the discovery. Understanding how budgies speak could provide a clearer picture of how speech works—and how to fix it when things go wrong.
The next step for Long’s team is to decode budgie speech. By analyzing their chirps and warbles with advanced technology, researchers hope to discover whether the meaning behind their sounds is as sophisticated as the brain system that produces them.
If successful, these tiny parrots may not only help us understand the origins of speech, but also challenge long-held beliefs about what makes human communication unique.
