Minecraft wiki entry for Parrot, associated text: Parrots imitate the idle sounds of nearby hostile and certain neutral mobs (including the hiss of creepers for example); they have a detection range of 20 blocks (cubical). The sound produced by the parrots is simply the same sound as the mob being mimicked at a higher pitch. They tend to look in the direction of the mob they are mimicking. Occasionally, a parrot may imitate sounds of mobs that are not in the area.[4]
