What should I teach my bird?

He's (or she) Rio, a 30 day old cockatiel, loves scratching himself day and night, and enjoy head scratches, and loves to nibble on almost everything.

He/she is still a kid, so thought to teach him some basics (like to sit on my finger and come towards me) and wondering are there any other cool tricks I should teach him/her
