Comet is just one of those birds that moves much slower than the rest of the flock... not sure why, but he just does. So when I started training him to roll over, it was slow going. I called Dave in to see my progress and said, "It's like he does it in slow motion!" and Dave said, "But that's kinda cool, keep it that way!" So I thought about HOW to keep it that way, and found a way... My open palm is the cue (like you've seen with my galah, Bandit) but I control how fast Comet rolls by the speed of my hand going OVER his body. So to get him to go super slow, I raise my hand slow and hold it by his side... so Comet lifts his foot slowly and starts to turn his head, then I move over his body a little and he starts to tuck under for the roll onto his back and as my hand is center over him, he goes on his back and stays there, then I slowly pull my hand over the rest of his body and he rolls up with the movement of my hand. It's like a cue for how fast or slow I want him to go. I can now get him to roll over real fast or real slow and it makes a great trick and a laugh for showing a trick in "slow motion". Here is the fast version:
