Hi all I have an umbrella cockatoo who is 3 years old and I?ve had him for 4 months now. I just have two questions. What does it mean when my bird is regurgitating and is it always voluntary orrr? And I never see him regurgitate on his own so I?m just wondering what it actually means. It?s always when he?s in bed with me. Cuddle time and all. Also, are cockatoos one person birds? I?m trying to socialize him as much as I can. Thanks u guys.
