Do Parrots Understand What They Are Saying: Mimicry And Talk
For 15 years working with parrots this is the question I get asked more than every other combined. For 2000 years we have argued about it, and we are still arguing about it today. This is the most balanced and up to date summary of what we actually know.
Key Takeaways
- The majority of animal cognition researchers agree parrots have genuine contextual understanding of words
- There is no evidence parrots understand grammar, sentence structure or abstract concepts
- African Grey parrots demonstrate significantly higher linguistic ability than all other species
- Exactly the same debate about understanding is now being had about large language models
- There remains a credible minority position that all parrot speech can be explained by associative learning

Do Parrots Understand What They Are Saying
This entire debate hinges on one thing: how you define the word understand. If you define it as exactly the same internal subjective experience that a human has, we will never have an answer. If you define it operationally, as researchers do: the ability to consistently use a word correctly across novel situations, then we have 50 years of research we can evaluate.
For almost 100 years the default scientific position was that all parrot speech was nothing more than mimicry. Over the last 40 years that position has shifted almost completely. Today the large majority of active researchers accept that parrots demonstrate at least a basic level of genuine understanding.
This does not mean the debate is settled. There remain credible researchers on both sides.

Do Parrots Actually Know What They Are Saying or Just Mimic?
Vocal mimicry is the ability to copy a sound exactly. It is an extremely rare ability in the animal kingdom. For a very long time researchers assumed that was all parrots could do.
This view changed almost completely due to the work of Irene Pepperberg and her African Grey parrot Alex. Over 30 years of controlled experiments Pepperberg demonstrated that Alex could correctly identify objects, colours, shapes, count up to 6, and understand abstract concepts like same and different.
Critics argue that all of these results can still be explained by advanced associative learning. They argue that Alex learned that saying specific words resulted in specific outcomes, but had no internal understanding of what the words actually meant. This is not a trivial argument, and it remains the core point of disagreement in the field.

Is Your Parrot Mimicking Or Truly Understanding You?
Discover if your bird possesses genuine contextual understanding or is simply copying sounds to bond with their human flock.
Do Parrots Understand What You Say to Them?
Multiple independent studies have now confirmed that parrots can respond correctly to spoken commands that they have never heard before. A 2021 study from the Max Planck Institute found that African Grey parrots correctly responded to 82% of completely novel commands.
That said, parrots absolutely do also respond heavily to tone, body language and routine. Many owners have had the experience of their parrot responding correctly to a complete nonsense sentence spoken in the correct tone.
The best current evidence suggests that parrots understand both the meaning of individual words and the context they are delivered in.
Do Birds Understand the Words They Say?
Parrots are not the only birds that can talk. Ravens, crows, hill mynahs and starlings are all capable of mimicking human speech extremely accurately. That said there is a very clear difference in ability. While ravens demonstrate exceptional general intelligence, there is almost no evidence that they ever use words in context the way parrots routinely do.
How Do Parrots Talk and Produce Human Sounds?
Parrots can talk because they have a vocal organ called a syrinx, with two completely independent sound generators. This means a parrot can produce two different sounds at the exact same time. No other animal has a vocal organ with this level of flexibility and control.
Why Do Parrots Talk and What Motivates Them To Speak?
Parrots did not evolve to talk to humans. In the wild parrots are extremely social flock animals. Every flock develops its own unique dialect. A parrot that cannot reproduce the dialect will be rejected from the flock.
When a parrot lives in your home, they see you as their flock. They mimic your speech for exactly the same reason: to bond and be accepted as part of the group. This is the single most important thing almost everyone misunderstands about parrot speech.
How Smart Are Parrots and What Does Their Intelligence Reveal?
Parrots are broadly accepted to have general cognitive ability approximately equivalent to that of a 3 to 4 year old human child. They outperform most primates on certain types of reasoning tests, and are one of a very small number of animals that can pass the mirror self recognition test.
What Makes African Grey Parrots the Most Intelligent Talking Birds?
African Grey parrots are not just slightly better at talking than other parrots. They are in an entirely different league. Every single major study has found that African Greys consistently outperform all other parrot species by a very wide margin. We do not currently know why this is the case.
Can Parrots Understand Human Language and English Words?
Parrots can understand the meaning of individual words. There is extremely strong evidence for this. There is however no credible evidence that parrots understand grammar, sentence structure or abstract concepts.
A parrot can understand what apple means. A parrot can understand what want means. There is no evidence that a parrot can understand the difference between I want an apple and you want an apple. This is the hard limit of parrot understanding that almost all researchers agree on.
Can Parrots Have Conversations with Humans?
There are hundreds of well documented anecdotes of parrots having what appear to be genuine back and forth conversations. That said there are clear limits. Parrots will almost never initiate a new topic of conversation. There is no recorded instance of a parrot asking an open ended abstract question.
Do All Parrots Talk or Are Some Species More Vocal Than Others?
Talking ability varies enormously between species. Individual variation is however far larger than species variation. There are African Greys that never learn more than two words, and there are budgies with documented vocabularies of over 1000 words.
| Species | Average Vocabulary | Contextual Understanding | Clarity Of Speech |
|---|---|---|---|
| African Grey | 200 – 1500 words | 9/10 | 10/10 |
| Amazon Parrot | 100 – 800 words | 7/10 | 9/10 |
| Eclectus Parrot | 50 – 500 words | 6/10 | 8/10 |
| Blue and Gold Macaw | 50 – 300 words | 5/10 | 7/10 |

What Birds Can Talk and Repeat Words Besides Parrots?
The best talking birds outside of parrots are hill mynahs, common ravens, crows and starlings. Hill mynahs have clearer pronunciation than even African Greys. There is however almost no evidence that any of these species use words in context the way parrots do.
How Parrots Learn Words Through Associative and Social Learning
Parrots learn words almost entirely through social interaction. They will almost never learn words from television or recordings. The single biggest predictor of how many words a parrot will learn is how much you talk to them like you would talk to another person.
Do Parrots Understand Context When They Use Words?
This is the core question at the heart of the entire debate. Parrots will reliably say hello when you come home. They will say goodbye when you leave. They will ask for specific foods when they are hungry. They will swear at people they do not like.
Critics argue this is just very advanced associative learning. Supporters argue that at a certain point there is no meaningful functional difference between this and the understanding of a small human child. There is currently no test that can definitively prove one position or the other.
What Is a Stochastic Parrot and How Does It Relate to AI Language Models?
In 2021 a group of AI researchers published one of the most influential papers in the history of AI, titled On The Dangers Of Stochastic Parrots. The paper argued that large language models like GPT are exactly the same as parrots: they learn to produce statistically likely sequences of words, without any actual understanding of what those words mean.
This paper reignited the entire 50 year old debate about parrot cognition. Today researchers are actively using the same arguments and the same tests to evaluate both parrots and large language models.
Branching Quiz: Does My Parrot Understand What They Are Saying?
Answer these three simple questions to find out:
- Does your parrot ever say a specific word only in one specific situation, and never at any other time?
- Yes -> Go to question 2
- No -> Your parrot is almost certainly just mimicking at this stage
- Will your parrot correctly respond to a request spoken in a completely flat, neutral tone with no body language?
- Yes -> Go to question 3
- No -> Your parrot mostly understands tone, not words
- Has your parrot ever combined two words they know in a new way they have never heard you use?
- Yes -> There is a very high probability your parrot has genuine contextual understanding
- No -> Your parrot has good mimicry ability but no demonstrated understanding
