Why does leopard print material scare my African Grey parrot? - why does my african parrot do that

I have an African gray parrot, who is 6 years. For some reason, if you ever get a leopard print on it, fear and begins to cry and scream like nothing I've ever seen! Obviously he has never seen a leopard before, so it's just the natural instinct of nature? Are all African Gray to act, or is it just me?
