I dunn know much about clicker training, and the videos don't work for me. But! I can say with a thousand percent certainty, that the quickest way to a bird's heart is through their stomach. Whenever you eat, let Alfie hang out on the table and eat off your plate. Talk to him! Sing to him! Tell him jokes. I share all my meals with my Timmy. He loves it. I've never done any formal training with Timmy at all, but he's fairly well-behaved, while still being mischievous, which I like.
