How do I get my parakeet to bond with me?

I have a male parakeet. He is the only parakeet I have. I’m not sure if he is hand raised or not. He did used to have a male and female with him but I no longer have them. (Long story.) He will sometimes go onto my finger, but he is usually afraid of my finger. I want him to be comfortable with me so that I can take him out more easily and have him stay close to me when he’s out. I know that this won’t happen over night and I am willing to take as much time as needed. I’m also looking to see if I can teach him to talk. One other thing, does anybody here know how to read the rings on birds feet? I’d like to know his birthday and he has one. Any help is great.
Serious answers please.
