Hello I have a male cockatiel named Klaus. He is over a year old and we’ve had him since he was 2-3 months old. For the past 2 months he has been screaming randomly to the point we’re I think something is wrong with him. I took him to the vet and he’s healthy. My vet said to maybe consider a friend for him but he’s never been around other birds and I don’t have the time for two birds or the money. Klaus gets daily attention for multiple hours. He’s out of his cage for well over 6 hours a day . Recently when I take him out of his cage he begins to scream and doesn’t stop for 2-3 hours later . We are in the same room as him and he will sit on my shoulder and still scream. I make sure that it’s not to loud in the room, it’s nice and warm in the room and make sure his food is filled and he has fresh water . Whenever he is quit I make sure I give him lots of attention but it’s been hard lately with him screaming constantly . What can I do to try and get him to stop screaming while we are in the room with him ? I’m not sure what he wants and I don’t know what to do at this point
