Oh yeah, we had a small conure that would talk. I used to tell people DO NOT PICK UP THE BIRD! no matter how cute he is.
He'd say "I'm a pretty boy" and other cooing phrases. Then the moment someone reached over to pet him he would leap onto their arm, run up and start biting their neck. I don't know how many times I peeled that vicious bird off someone. He would bite me too while I was getting him off them and backto his cage.
A toucanette is a small toucan. They eat dogfood and fruit. He was so cute. He had such an attitude like "I'm a Tooke, tooke, tooke." He looked like a Z. He was 1/3 beak/ 1/3 body and 1/3 stiff tail. He couldn't fly very well so he would take off and then when he reached his branch, he would grab onto it with his feet and full speed. Bang and he would tip over and then recover and look like he had planned it that way all along.
African greys are amazing and super intelligent.
Yes, I remember reading about one named Alec who could talk and make sense. He knew words for things and didn't just repeat stuff. I think animals know more than we give them credit for.
We had a parakeet back when I was a kid, and we left his cage door open so he could come and go as he pleased. He would fly into the bathroom and hang upside down looking into the mirror for hours. When we ate, he would fly onto the table and join us at meals. The drawback to leaving a bird loose is that one day when my grandmother was letting the cat out the back door, he landed on her head, as he often did with us. She felt something on her head and reached up, scaring him, and he flew out the door, never to be seen again. Philadelphia doesn't have the climate that would enable a parakeet to survive, so I'm sure he must have died, at least when winter came. I had other parakeets after him, but none were so tame and companionable.
When we lived outside San Francisco, Bill told me there was a place near Daly City, I think, where there was a whole flock of parakeets, all escapees, most likely. I guess winters were mild enough in California that they could survive.
They are parrots. They made a movie of it. Its a good (sad/happy at the end) movie. More like a documentary.

We had a lovebird....only one....my husband raised him from a baby, too. He loved us until he laid an egg....(oops, not an Elvis anymore). Then he/she got real protective over the cage area and started biting us. He got outside once but never left the area though. Went from tree to tree. I heard once they get up it's hard for them to come down. He finally worked it out and we got out there with a ladder and his cage and held it high and he came back to it. He was a mean little bird though. When he died we buried him in the backyard with a little pirates ship as the "head stone".

not a pretty picture.
