What a beautiful Cockatiel. She is so healthy and friendly looking. My mom has a Cockatiel as well. His name is Butterfly, she named him not me, and he is getting along. I am not sure how old he is, but I know he does not like strangers. Even when he was young, he would bite and hiss at anyone he didn’t know. He has vanity issues too, absolutely loves looking in the mirror and looking at himself.
