well,
its clear that the budgie is guilty of something-why else would he be confined to a cage?. he's got troublemaker written all over him, better to take no chances with him and classify him as an enemy combatant.now you can pluck a feather or two until he confesses.
then,after a fair and impartial trial by you and your friends,you can hang him in the morning.
any of his budgie friends come looking for him,do the same with them-the war on budgies could go on for ever but you got to start somewhere!
sudden
we come in peace(shoot to kill)
