ATIEL ISSUE! Should my bird listen to other atiels on youtube?

It's fine for her to listen. She will probably enjoy it very much. But if you know for a fact you have a female, don't expect to much from her as far as learning certain tunes to whistle and for sure, don't expect her to talk. Only the males talk and rarely does a female learn to whistle tunes. It doesn't mean though that she cannot enjoy hear the others birds.
