The prey of the vampire bat is so extensive as to include sea lions and pelicans that inhabit the regions of coastal northern Chile. Near human settlements, however, it prefers to feed on a variety of domesticated animals such as chickens, cows horses and pigs, which do not move about at night.
吸血蝙蝠的獵物包括生活於智利北海岸的海獅和鵜鶘，在接近人煙之處，它們則以生禽、家畜為主食，雞、牛、馬、豬這些在晚上不甚活躍的動物，是它們較中意的對象。
