Wrench13: I can only vouch for the Amazons I have had, never owned a grey or cockatoo. One was a really good talker and mimic and would copy the pitch and sound of a given voice. Salty has at least 4 voices he uses, mine, my wife's, some he has picked up from Youtube videos, and he has his own 'robot' voice.
I'm wondering if the Robot voice is what they hear coming from the digital media such as youtube, TV's, DVD's, etc.... Although we can hear it in it's sharpness and clarity, pitch, I wonder if when it comes from one of those sources if the sound is heard differently, almost like for instance, the other day I watched a "Denzel Washington" movie "Man on Fire" and as it started off my English Bulldog was Howling, I immediately paused the movie to see if there were sirens going off somewhere, knowing that sound hurts his ears, and no siren, and he stopped howling, I started the Movie again, and immediately he started howling again. I joked clearly he must not be a "Danzel Washington" fan, but the fact clearly, he heard something in the music playing in the intro that I couldn't hear.
Sailboat:Never underestimate where one's Parrot is learning Language! In today's World of voice based tech stuff, which is everywhere. Having a Parrot speaking in a robot like language will become ever more common.
As stated, species does play a large part in variation in tone, pitch and cadence.
Sailboat, I know the Cockatoo talks in it's own voice, and I've rarely been able to tell if it's had a male or female source, but as it mimics words, their in it's own tone. I just found the Robot, mechanical voice really freaky, I really enjoy the Male/Female mimics of most birds, and realize the Cockatoo has it's own voice, But I've heard the Robotic voice coming from a Cape Parrot, from African Grey's, and even once from an Electus. Of course my curiosity was on fire, because I did dislike the voice very much, I do want to learn more about the source. I've "Google"d this question, I've searched it being asked a dozen different ways, and all I get are dead ends. The other day I asked a question to you privately, in relation to my daughter and her family, reference to the Amazons Temperment, One avenue I've never explored was the "Cape Parrot" The Cape Parrot seems to be much more fitting to my daughters family, and the more I read, the more I like what I'm reading. My granddaughter is a very mature 5 year old, who has her PawPa's heart for loving pets. Of course I'll wait until she's older without a doubt, and in the meantime, I've looked over our forums, I don't see a forum for Cape Parrots, I think they must be integrated with "other" parrots, or in with the Senegals. However I haven't really read any threads directly related to behavior, temperament, foods etc for the Cape Parrot, But I have read several articles about their independence, their vocabulary potential "although you and I spoke about reducing the wants in your bird, and be more receptive to what you get and love your bird for what you get" which is some of the best advice I believe has ever been spoken, and I heard it well. Although the Cape is a fairly Quiet parrot, very content to play with it's toys, finding a hand reared, baby mixed with these traits seems almost too good to be true. I also read if the opportunity presents itself to grab one of these guys as a pet, think hard, and think twice before passing up on the opportunity. I know your an Amazon guy, between you and Wrench13, and I really appreciate both of your knowledgeable replies to my questions, I was thinking if I provided her with an Amazon Parrot, she would have to be much older, and if I decided to go with a Cape Parrot, Then she could possibly be a responsible owner at a younger age. The Robotic voice came up as I was watching a you tube video, and that stopped me dead in my tracks. My grand daughter loves to sing karaoke from my daughters house, has her little box and microphone, and sings all day long. She loves to attend church, and sings at the top of her lungs to different hymns being sung in church. My daughter tells me, She cannot wait to join the children choir lol. So if I'm correct, in the bird picking up the Robotic voice from Sources such as DVD's, TV's, YouTube, and even through the radio, I'm really worried if it starts speaking in the freaky Robotic voice how she will react, knowing she's a lot like me, and I dislike it lol, anyways that's why I'm asking, and for whom I'm asking. The other thing I dislike, is the Cape Parrot is said to have about a 30 year life Span, So I was looking for a bird who would accommodate her to about 75 years old, A pet that she will always associate with as a gift from me to her, hopefully that doesn't seem strange, but I do want to pair the two in a long term lasting relationship, where they could possibly bond and be happy with for her life span anyway.
I am sorry I had to highlight your answers as I did so I could answer them separately, I'm not familiar with how the multi Quote button works, I'll have to ask that question, for in the future.
