i use to go to our local bird store every few days... The owner had baby parrots , hand fed all the time.. I fell in love with th gray's . Some of her parrots were outside of their cages. The Macaws, and Cokatoos, have ear splitting screams. A pioneous, and African Gray were on the quiet side.
Some day I'll have my gray ! The Congo Gray is the bigger of the two. I have heard that they really don't start talking untill at least a few yrs. old .There was a famous gray named Alex. He understood what to do on command! He was owned by a Scientist who studied his intelligence for yrs.
