I have an 8 year old Congo ... she just makes sounds...
her previous owner had a Macaw that talked his head off...the congo imitates cell phone ringing, answering machine, smoke alarm dead battery beep,microwave!, water drop... but no talking. I taught her to whistle Andy griffith (she does part of it lol) and the Blue-skiddo song from blues clues) so she can learn...
shes only been with us since June, and she just recently got groomed and ignored me for two weeks after that.
Shes back to whistling away. I hope someday she will talk. Only time can tell with yours and mine!:whistle:
