New owner of rescue Indian Ringneck

Hi everyone,
First time on this and I am looking for some help. I adopted a green INR a couple of days ago from a local shelter in Victoria. They said it was a boy and bites. But I feel inlove with him and felt he has spent enough days at the shelter (over 500 days). Seems to have settled in new home and loves broccoli, red capsicum and corn.
So I am looking for advice on how to get him to trust me and if it is a boy. I am talking to him and slowly approach the cage so he doesn't get a fright.

Thanks in advance
