Brazilian funnel-eared bat
The Brazilian funnel-eared bat ("Natalus macrourus") is a South American bat species found in eastern Brazil and in Paraguay. It roosts in caves, which makes it vulnerable to disturbance of these scarce sites, and in particular, to extermination campaigns against cave-roosting bats carried out in Brazil to combat rabies. It was formerly considered a subspecies of "N. stramineus". Abiotic factors such as temperature and annual rainfall can affect the distribution of this species. References.
