The grey hypocolius or simply hypocolius (Hypocolius ampelinus) name hypocolius likely originates from the Greek word hypo, meaning "below" or "under," and "colius," which may be a reference to the genus Colius, the mousebirds, or an incorrect Latinization of cilla (tail) from "wagtail" (Motacilla). The grey hypocolius is the sole member of its bird family, Hypocoliidae, making it a unique species. It's known for its distinctive black mask in males, soft grey plumage, and long tail, which give it a waxwing-like appearance. It is found in the dry semi-desert region of northern Africa, Arabia, Afghanistan, Pakistan, and western India.
