I love my budgies.
The female is quite reserved, but the male flies around a lot more and i can get him to perch on my hand. If likes playing a game where he bites the shit out of my fingers too, it doesn't hurt and he looks happy. I yard a finger about and he attacks it.
The female likes lettuce, and the male doesn't so if likes grabbing the lettuce and flinging it off the top of the cage. I have to secure one piece so she can eat it.
I never close the cage door, because i love them.
