Carollia
Carollia is a genus of bats often referred to as the short-tailed fruit bats. Along with the genus "Rhinophylla", "Carollia" makes up the subfamily Carolliinae of family Phyllostomidae, the leaf-nosed bats. Currently, nine species of "Carollia" are recognized, with a number having been described since 2002. Members of this genus are found throughout tropical regions of Central and South America but do not occur on Caribbean islands other than Trinidad and Tobago. Bats of the genus "Carollia" often are among the most abundant mammals in neotropical ecosystems and play important roles as seed dispersers, particularly of pioneer  plants such as those of the genera "Piper", "Cecropia", "Solanum", and "Vismia". "Carollia" are primarily frugivorous; however, "C. perspicillata", "C. castanea", and "C. subrufa" are known to feed on insects. Genus Carollia – short-tailed leaf-nosed bats Vocal Diversity. There is evidence that there are distinct differences in vocal behaviour during physical interference interactions at the perch between sympatrically living, closely related species of "Carollia". This diversity of vocal behaviour may arise from different ecological pressures during allopatric speciation, and may also be an indicator of differences in species social organisation.
