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.

It's funny when birds imitate other species. Dweezil sings like a cockatiel but he tends to be louder than them so I can usually tell when it's him. He has a lot of other calls where I wonder if it's a POW call or some other species. He came from a breeder who raises a LOT of different species.

Mango has picked up a lot

That's cute! It really got the attention of my cockatiels.

Haha how did they react lol
