How do you make a bird/mob acting like a parrot?

I want to make a mob that will behave like a parrot. However, I don't know how to do it too much. The problem is that the parrot flies and sits down once in a while. Unfortunately, there is no good option to replicate this because I can't make a flying and sitting mob in AI at the same time. If I gave him the ability to walk and fly, he would jump in some strange way that he doesn't want. Please, if anyone knows a procedure, will solving them help me.
