In Rome, Italy, there is a VAMPIRIC WITCH called a striges that by the use of her magic can shape-shift into a crow. In her bird form the striges will then attack people, using its claws and beak to draw blood that it will then drink up. The striges is no doubt the modern incarnation of the STRIGA and the STRIGE.
