Part of why Ravens are considered Spooky Bad Things We Associate With The Faeries is because they can and do mimic human speech - but much, much better than a parrot. With a parrot, you can tell something is off about the sound. You can tell it doesn’t belong to a human. Ravens don’t sound like that, no, cause they’re overacheivers. (And passerines). They sound EXACTLY like the voice of whoever they are mimicking.
But more importantly they love the sound of human laughter. No one knows why. But it is totally, 100% possible, and it happens to this day, to walk along the paths in the Black Forest and suddenly hear a strange kind of giggling sound, or maybe even a very clear, definitely human sounding “hello?” “Hiiiii!” Or “let’s go!”.
However, it takes a lot of practice for them to copy sounds as perfectly as they do, so you’re equally likely to hear something that definitely sounds human-like, but the words make no sense and the sound is unlike any language you know.
Ravens at the Tower of London do this all the time. Theyre pretty sociable with humans though, so they do it quite openly. I have seen videos of people, mostly Americans, look absolutely spooked out of their skins when a big ol’ raven (mind ye, these are birds that are 2 feet tall with a 5 foot wingspan) comes waltzing up on the deck and starts talking to them.
And ravens, especially the ones there that have been bred and raised by humans for centuries, don’t just imitate - they have one of the same language processing genes we do, and they understand the way a toddler might that things, places, and individuals have names, and can string together basic sentences much like an african grey.
I know because I used to work with one, Darlene, who knew, quite well, what she wanted and how to ask for it. If you were preparing her breakfast, she would hop on up and investigate. She used to be an illegal pet, and had been taught “manners”. That is to say, if she went for something and you told her, sternly, “mind your manners missy!” She would stop, look at you, perhaps for up to a minute, and then point with her beak to what she wanted. If that did not work, she would ask, in plain English, “grape?” Or “Darl have grape?” And lord help you if you gave her anything less than what she asked for. She would throw it at you, and try to bite you, sometimes while saying “No!” In the same tone as I imagine she was reprimanded in her home.
So yeah. Parrots arent the only ones.
