Rainbow lorikeets are a species of parrot, found living wild only in Australia, that have exceptionally bright and colourful plumage across both sexes. Indeed, the sexual dimorphism that is very common amongst birds (please see this post: https://zafoid.com/post/view/12711) does not exist in rainbow lorikeets, and the males and females cannot be visually told apart (short of DNA testing or endoscopic inspection). Rainbow lorikeets themselves distinguish each other's sex primarily through distinctive behavioral cues, vocalizations, and subtle physical differences that are imperceptible to humans.
