Me and my family owned 2 Ringneck Parrots in our life!! They are very cute and very fun!! We had them at separate timings. They get to a big size, and they can bite, but since they are big parrots they should be easy to train. We got ours at a very young age, like when I was 5 or something. We never took him out of the cage because the adults where afraid of us letting it free (which is btw how it accidentally got out lol) and because the potentially fact of it biting. But neither ever bit us, very friendly and cute.
Go online and search some tips on how to train and raise these two birds, hopefully that'll help you make a differentiation between the two. I cant give you much info on Plumhead parrots since I never owned one, but im sure there's a lot online.
Feel free to comment my answer and ask me questions about Ringneck parrots or first time parrot raising, I'll be happy to answer!
And have fun with your new Parrot once you decide. Remember Parrots need LOTS of attention. In the wild they are used to being surrounded by their fellow birds because they live in flocks. So make sure to give it lots of attention :)
Hope I helped!!
I need some info ASAP please. By the way it'll be my first bird
