Hello, I recently adopted a 3 year old male GC conure who grew up with an African Grey and also baby conures as the owner was a breeder. She said he was becoming too territorial over her grey who was older, and i assumed it was due to hormonal behaviour. After a week he started perching in high places, sort of crouching down, shaking his wings, and letting out the loudest screech I've ever heard from a bird (and i grew up with a cockatoo!) The first week I had him he kept trying to mate with my shoulder, but since I kept telling him no and putting him on his perch to stop it, he has changed to this awful screech! Is it just hormonal? Could he be trying to call out for the birds he grew up with? I love him dearly but I've had complaints from neighbours about his screeching, despite as I said, previously owning an umbrella cockatoo. Its really quite the ear piercing sound...
