I got a cockatiel almost 2 months ago now and it is no closer to being tame or bonding than it was when I got it. It hisses and bites, and man does it bite hard sometimes, and then just tries to get away. It isn't sociable and I mean that. It doesn't care if someone is with it or not. I don't think it could be any less interested in me if it tried. It sings and chirps every day and when it isn't, it is preening and beak grinding. But then it bangs the cage and screams at me but runs when I approach. I know it's screaming at me because after it screams it turns its head at me to see my reaction, but believe me, it doesn't want attention because that just makes it scream louder. I think it enjoys trying to irritate me, because it loves to scream like that when it hears my voice. It isn't a nice scream. It's this horrid shrill little noise that repeats over and over. I open the cage but it doesn't come out. It chews its perches and toys aggressively and it just seems really angry. It can't be bribed by food or treats because again it isn't interested. It doesn't bathe itself. I have tried everything but all the articles I read and forums I scour say that the bird should want socialization and contact or attention, but this one doesn't. It doesn't play with its toys, only destroys them. It hisses and lunges if it even thinks you are going to put your hands near. Like I said, it bites, and it's like the thing is so angry and hateful. I don't think it's biting as a defensive mechanism, it really just seems to hate everything. I was told this bird was 6 months old. It also has a bit of a malformed left leg but no it doesn't cause the bird any pain or anything, it is a disability from birth. It can climb and fly and everything just fine. It has a big cage, toys, treats...but it acts so horrid and disinterested/distrustful. How do you bond with a bird that doesn't want to give you the time of day? This is my first bird and man it really seems like I got a doozy.
