yes technically parrots can recognize, and recreate sounds, it’s not that they understand english, or words, or language. It’s that they’re capable of recreating vocal anomalies of human speech, pretty well. Likewise, i can also mimic someone else speaking in another language, or just individual words, but that doesn’t mean that i’m speaking the language.
You’re repeating the age-old myth of “parrots just parrot, they don’t actually understand anything they parrot”.
This is decidedly untrue, and there’s heaps of science behind that. A lot of which I have shown you. So that assertion is proved untrue, ie “wrong”.
ethics, is an english word. It comes from the english language.
This is also just plain wrong. It’s a Greek word that comes to English from Latin. So not an English word, actually. (See my first point about monolinguistic speakers often being a bit ethnocentric. Not your fault, one language is limiting in more ways than one.)
Parrots can indeed speak, but to what extent do they actually understand the language, or have grammar? That’s the video I linked in my very first reply.
