I like to use the term peafowl when refering to 'peacocks'. Even some peafowl breeders refer to all peafowl as peacocks.
The truth is, the word peacock is refering to the male bird. The word peafowl refers to the species as a whole. That is why I call them peafowl instead of peacocks. A hunter wouldn't call all deer does and say to people that he shot a 10 point doe when really what he shot was a buck. Would he? No, he would say he shot a buck.
