This trick took Kiwi about 15 minutes to perfect. It started out with just touching the card with his beak - he'd get a click and a treat. Then it progressed to him picking it up - he'd get a click and a treat. And then when he turned it over he'd get a click and a treat but he would no longer receive a treat for just bumping it with his beak or picking it up. The next step was to get Kiwi to realize that he didn't need to turn it over and over and over. Just flipping it over was enough for a treat.
