OK, for all of you who dont get why mirrors are a bad idea:
Birds can have one of these two reactions:
a) they fall in love with the mirror, act like it is a mate, feed the mirror ect.
They can get really possessive of the mirror, attack anyone that comes close to it, let alone remove it. They can become one-mirror-birds and refuse to interact with anything but the mirror. They barf all over the damn thing and then rub their own face in it and thus breathing and swallowing day old puke.
b) they look at the mirror as an adversary, an enemy, somebody invading their territory. Ofcourse that somebody will be needing a big whoop-ass so it will know never to come into his territory again. But sadly enough, the bad guy stays and doesnt mind his daily beatings. It will become a daily ritual, even a fixation of the bird to get that mirror out of his cage. Sometimes it can escalate so that the bird will be driven out of the cage by the mirror and refuses to go in again.
So you see. Either way, its a bad idea. Mentally.
@ Rue: Good thinking
