Hello, my 5 year old double yellow headed amazon is continuously making annoying sounds similar to groaning or moaning as if it wants somerhing. I truly have no idea what it could be as my parrot is well fed, hydrated and physically active. I doubt this noise is learnt from my family members or television because we have never heard or done it before. It has been doing it for roughly 2 years now and he still does it even when I try to play with him. I have videos of my parrot doing it. Could you please respond to me when you read this. I'd appreciate it a lot. Thank you.
