My male cockatiel is usually pretty comfortable and loving around me if not somewhat indifferent, but I’ve noticed something weird lately. I know not to give my cockatiel mirrors as they tend to get obsessive over them, but sometimes my cockatiel finds a way to talk to his own shadow/reflection. Usually its fine and if I take him away early enough he doesnt seem to mind but if im too late to notice he gets really aggressive about me asking him to step up. I also played some cockatiel videos for him so maybe he’d feel less lonely and the exact same thing happened. Maybe the simple solution is making sure access to these things is limited since these are both things that I can control with relative ease. My concern is making sure my boy is happy. If I get a second tiel will he become aggressive toward me? Is getting a second tiel even something to consider since im spending so much time with him? Has anyone experienced similar? How do we work on this behavior?
