Olive Ringneck

Hello everyone I have searched but not found an answer.
I have a young ringneck not sure of gender yet. He (hoping for a boy 😃) bites a lot but I don't believe he is trying to hurt me although it's very painful. He will step up and hang out but maybe gets bored? He starts by nibbling almost like he is tasting my finger or arm then latches on and draw's blood. I'd love to break this habbit if anyone had idea's please share. Thanks James
