New progress update, the Pink Cockatoo I've been training now comes out of his cage. The training we've been doing is paying off. He targets onto a handheld perch and I can gently carry him over to the nearby Training Perch. The parrot steps onto the Training Perch and our training can go even further outside the cage. The Cockatoo is getting more and more used to me, the environment, and the routine.

The training tools I use are:
Clicker
Target Stick
Treats
Handheld Perch
Training Perch

All of these and much more can be found from Parrot Wizard.
