How does a vampire bat find and get blood from its host?

Do vampire bats feed on blood?

Vampire bats are sanguivores, organisms that feed upon the blood of other animals. They are the only mammals that feed exclusively on blood. Despite horror-movie depictions, vampire bats very rarely bite humans to feed on their blood.
