Hi. I’m a new member and need some advice. A bit of a back story, I got 2 Cockatiels 2 years ago, a young female and an older male. The male has always been protective of the female and they’ve been inseparable. A couple of days ago the female passed away (she had underlying health issues) and now the male is aggressive and he squawks all the time. He’s only quiet if me or my nephew are near him but doesn’t let us touch him. He’ll gladly sit on our arm at his own will though. We’re thinking of getting him another cockatiel friend to keep him company. But don’t know if that’s a good idea considering he’s being aggressive to us? I just need some advice. Thanks
