There actually have been animals that acted the opposite "role" of their sex of their species (like doing male mating dances as a female) while staying the same sex. The most common method is due to brain altering parasites/viruses but I think there have been some that changed because they needed for it to happen (ie the main member died) and even some where it just happened for no reason at all and they were considered an oddity.
