They are all rescued owls, given up or abandoned when their new owners realised how much work is involved in keeping an owl as a pet. See the hand of the man who is these owls best friend. This is how they love you, it's just the way they are, very territorial!
I did learn an interesting thing about owls. Their eyes are fixed, so although they can zoom in and out they don't have any peripheral sight, hence why they are constantly turning their heads.
