A vampire bat can only survive about two days without feeding, yet they cannot be guaranteed of finding food every night. This poses a problem, so when a bat fails to find food, it will often "beg" another bat for food. A "donor" bat may regurgitate a small amount of blood to sustain the other member of the colony.
This causes a problem for the human population because these colonies can get quite large, in fact much larger than the Pipistrellus pipistrellus colonies, which tend to be fewer than 200 bats. This large size of colony causes a nuisance for humans because of the smell.

While the evening bat is considered endangered in the state of Indiana, [20] it has a cosmopolitan distribution throughout the southeast and midwest. [18] Because evening bats do not enter or hibernate in caves, the species is not at-risk from white-nose syndrome, which has killed over six million bats in the United States since 2006. [21]
“We were sideways, and then we were upside down, hanging like bats,” Koukov told CNN. He took video showing some passengers, still strapped to their seats, on the overturned jet. Nelson called ...
