Cockatiel bird says peekaboo to the feathers

My pet cockatiel Charlie has always been quite strange. For some reason he loves to talk and more specifically, say peekaboo, to his own feathers!! I’m not sure why he does it but I think it’s very funny. I reckon he’s probably the only cockatiel to do it!!! I’m not interested in making any money from this, I just want to introduce Charlie to the world. Thank you for reading.
