Hello,
I am assuming the ringneck has been in a pet shop for about a year and is now being handled. From your question, and from my experience, this seems to be typical ringneck behavior. Ringneck's are neophobic and frighten easy. Their brains are wired this way because they are animals that are preyed upon in the wild by predators. For this reason, your ringneck needs a little longer to adjust to you. He's scared right now and doesn't know what your intentions are.
What you can do is start a positive reinforcement program to help him get to know you and you to get to know him. Then, you can take him into a small bathroom or a quiet room and talk to him in a soothing voice. This should be done over and over and you should gradually work your hands into the equation.
Always use treats as this is the quickest way into any ringneck's heart. Also, browse through the forms as there are many other questions similar to this one.
I hope this helps and welcome to our forum.
Best wishes
