Sorry to jump on the thread so late, but from what I have been reading it sounds like Snow is a boy. Female tiels usually don't talk or wolf whistle, if they do, it's rare. Also, Ellen gave you excellent advice by googling different mutations.

Usually Lutino's are yellow with very red eyes.. My Piper (my profile pic) is a Lutino cockatiel. From what I can see in your pic, you have a whitefaced pied. Oh, I have one too!! He is Ellen's Grandbird
