Rileys problem

[Amina2000]

Hello everyone, my parrot Riley seems to be really aggressive lately his been biting and screaming really loudly I have no idea what's wrong with him.
but just now I realised that his growing new pin feathers onto of his head could that be the reason his been aggressive and also just wants to be by him self.

Welcome to the forums, thanks for joining!! Can you share some additional information about Riley? Type of parrot, age, sex if known, and how long you have been the parront?

The presence of pin feathers suggests molting, definitely a cranky time! Periodic hormonal issues are always problematic, as is the onset of adulthood. These are all issues a committed parront will confront, but knowledge of the general behavior makes acceptance far easier!
