Screeching Rainbow loorikeet
My 6 year old rainbow loorikeet (who I hand reared) has recently started making weird screeching noises (a deep vibrating noise). She does it when I come home and also sometimes whilst on my shoulder. She also makes high pitch screechs whenever she sees me. She never used to do any of this, there's been no recent change in circumstances that I can think of. She has a very large cage with plenty of stimulating toys and comes out everyday. Please help me identify whats wrong/ fix it before a very bad and hard to break habit is developed. Thank you.
