I think this might be less of an "angry" attack and more of an... ahem... orgasmic one. I had a cockatiel and we asked what that head bob motion was that he made all the time and were told that he was basically asking you to get him off when he did that.
I had a cockatiel whose mind was totally blown by a picture of a cockatiel on a big box of cockatiel seeds. Poopy started worshiping the box, trying to feed the giant bird and angrily defending it from infidels until I got sick of it and put the seeds in a coffee can and threw away the box. I am a jealous God.
Our lovebird has a toy consisting of miniature bells on a chain. He loves to feed the bells, lick them, abuse them and masturbate furiously on them. He will also go after them if you hide them, and will call out to them if he hears them jingle from the other room.
He has crawled through a hamster tunnel to get to the bells and climbed a five foot rope, in addition to other crazy activities.
