I know I've been watching loads of videos of them. There so silly they make me laugh soooo much!! I've never seen anything like them in my life. The way they bob up a down bounce around it just makes you smile. I don't think anybody could not love them!!
Well, what happens is that people become intimidated by them. The bird suddenly realizes that the person cannot control them, and that, in the opposite, he can control the person by screaming, or bluffing, or biting...
And then they don't love them so much!
I have told this story more than once, but I actually did an "intervention" on a greenwing, where a dominant bird was "in charge" of the house, and actually chased people around the room, with intent to take off toes...
I believe I was asked to get "THIS THING" out of the house.
Well, if you're dumb enough to run, the bird is going to chase you.
He came at me, beak open, wings out, full on charge... I grabbed the couch cushion, and charged right back at him. Backed his little butt into the corner, made him sit there and think about it a minute. Then made him step up nice...
He did.
And immediately lunged at his owner's nose.
Didn't even try to bite me after that.
Guess what happened when I taught the owner how not to put up with that nonsense?! They found out he was actually a pretty cool bird, once he learned his manners! In fact, the goofy came out in him...
So, Note to self... don't run.
