This reminds me of being told dogs don't feel emotions by someone who never owned one. Parrots most definitely can talk. Their language is extremely primitive but if you've ever been around a grey and it's owner for some time, they definitely talk to each other. The parrot will readily communicate observations and desires.

Isn't that what humans do too? We mimic noises we've heard before and we associate meaning to the noises. Parrots can do that. Our quaker parrot would bite you, then say 'not supposed to bite'. He clearly associated some kind of meaning to that phrase.

Common misconception. Parrots are much more than just mimicry machines. There is also Apollo the parrot that shows this in detail and following from Irene's research with Alex

Many animals can communicate.

Parrots can't speak fluent English, which shouldn't be surprising. Last I checked, no human is fluent in Parrot or Dolphin.

Though, at least one parrot may have demonstrated an ability to understand language at more than a surface level.

Bumblebee (the Transformer) might have an objection here. Purposeful mimicry can be used for talking on certain complexity. It does not have to be human-level to be communication.

This is also what toddlers do until bit by bit they're repeating everything you say back to you in context.

So do we, otherwise we would all speak our own individual language.

So what you’re saying is that parrots are stochastic parrots.

Like Starlings do.

I mean, isn’t that just what you’re doing too? If you see a cow, and you’ve been taught that ‘cow’ is the sound that describes a cow, don’t you say “cow?”
