This is Rio my lovebird that I rehomed only now he seems to be a Plum headed parakeet lol.
Mango mimicked his call from Tiko, Tiko used to do it very loud every time you walked by her cage and it would go through your ear.Parrots must have great hearing because my Uncle lives next door and he has a African grey named Bruno and he learned a lot of words and sounds from Tiko and Tiko learned from him too.
