The bat family Noctilionidae, commonly known as bulldog bats or fishing bats, is represented by two extant species, the greater and the lesser bulldog bats, as well as at least one fossil species, Noctilio lacrimaelunaris, from the Miocene of Argentina. The naked bulldog bat (Cheiromeles torquatus) does not belong to this family, but to the family Molossidae, the free-tailed bats. They are found near water in the Neotropics, from Mexico to Argentina and also in the Caribbean islands. In these areas they can be found roosting in groups within hollow trees, caves, manmade homes, or other openings with enough space. While the two species exhibit different social and foraging behaviors both tend to return to a main roosting spot while also visiting other alternative roosting spots.
