I have two birds and one will get mad the other for resting on my hand.
I don't why but he doesn't act like he likes us and he doesn't like the other bird to interact with us. He'll nod his head hard at the other bird for doing so. It's almost like he's bullying him. It's gotten to where the other bird won't interact with us. I told my hub he should get rid of him but he won't. We found him one day in the street. We think our old neighbor kicked him out because he was bullying the other birds. She had other birds. The bird that gets bullied here is new. We just got him. We got him as a companion for our older bird because we could tell he was lonely. The new bird was kind and fun and friendly at first but he's different now. It's almost like why have them if we can't interact with them a little. We even try talking to them and opening the cage but they won't leave the cage.
