Well, thank you! But it's mostly Burt.
Those are unshelled, unsalted (raw) sunflower seeds. He's only getting about 1/3 of a seed. I trained everything by shaping (at times you can see me giving him cues off to the side). The turn took about two sessions, 5-10 minutes a piece. With Sondheim, it took double the time. Sondhi is less motivated and younger.
I used a clicker and shaped tiny movements. Looking over shoulder, click. Moving feet to the left, click. I also used the seed as a tiny "lure" (holding it under him and having him follow it) And so on and so on until he was turning in a full circle. During that, I added the hand cue. It can be difficult to hold the clicker in one hand and seed in the other. I only use the clicker when training new behaviors. It's phased out pretty quick once the bird gets the cue.
The next behavior I train, I'll record the sessions.
