I had a ****atiel and he was gorgeous!! He took a while to settle at first but keep talking to him and interacting with him to get him used to being handled. My brother's one was always a bit cranky and would hiss at people, its just different personalities.
Pip (my bird) used to copy my dad's whistle and the sound of a spoon clanking on a bowl and make the phone ring sound! He also said "hello Pip". It was terribly sad when he died aged 7
