Strix (mythology)

The appearance and calls of owls, such as the Eurasian scops owl, may have influenced Greek ideas of the blood-drinking strix.

The strix (plural striges or strixes), in the mythology of classical antiquity, was a bird of ill omen, the product of metamorphosis, that fed on human flesh and blood. It also referred to witches and related malevolent folkloric beings.
