We’ve had a sun conure for about 5 years now and we have had problems with him. He is scared of everything. Even a banana scares him. He doesn’t let us pet him in certain spots like his stomach or he wont let us touch and see under his wings. He is also very aggressive to people except me and my son who he’s deeply bonded too. The previous owner told us he was attacked by a pitbull and almost killed. I was wondering if that trauma was why he is aggressive towards people and scared of certain objects.
