My lovebird (male, about 4.5 months old) has been acting weird lately. He's acting very paranoid and panicky in his cage when it is bed time (online time when he is in his cage). First I thought it was Night fright, but it also happens when it's still light. This has been going on for like 2 days now. He is also a little bit more aggressive (tends to bite my fingers when I'm just chilling behind my PC). What could cause this panicky behavior?? I checked if there are any bugs in/around his cage, but found nothing. When he was outside of his cage he was almost falling asleep because of his tiredness and now this. Is this because of his hormones? If someone has an idea, please let me know!
