In all honesty, once my conures got the hang of trick training, you didn't have to show them a behavior twice... because they already got it.
If you can break it down into steps to teach it to them... they will soak it up like a sponge.
What I like about Tani's series is that she teaches you all the little steps, and how to combine stuff your bird already knows, into other tricks.
For example, what is the difference between putting a basketball in a hoop, and what Baxter did in this video? You hand him a different object. That's all.
(THAT IS A DOLLAR STORE KIDS TOY, WITH A CAT BALL FOR A BALL. TWO BUCKS, AND YOUR BIRD ALREADY KNOWS THE TRICK. HE'LL PROBABLY GET IT THE FIRST TRY.)
Taking a little toy off a little doll house shelf, and putting it in a toy shopping cart? Guess what, same trick. That's just a go get it, and put it in here...
Push the scooter. Push the skateboard. Push the grocery cart. Same trick. Different object.
I think you're really gonna love this stuff! And Baxter certainly seems to have the temperment for it.
And if you do it right, for them it's just playtime. And they become super bonded in the process.
