|Scientific Name:||Chilonatalus tumidifrons|
|Species Authority:||Miller, 1903|
Natalus tumidifrons (Miller, 1903)
|Taxonomic Notes:||Formerly included in micropus (e.g., Hall, 1981) (Simmons 2005).|
|Red List Category & Criteria:||Near Threatened ver 3.1|
|Assessor(s):||Velazco, P. & Turvey, S.|
|Reviewer(s):||Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)|
Listed as Near Threatened because its extent of occurrence is probably not much greater than 20,000 km², and the extent and quality of its habitat are probably declining, thus making the species close to qualifying for Vulnerable under criterion B1b(iii).
|Range Description:||This species is known from Islands of the Bahamas (Simmons, 2005).|

|Population:||Females form maternity colonies in which they give birth to and care for their young. Females are completely responsible for the care of their young. Giving birth to just one offspring per event means that females allocate all of their efforts to the single young. (Burns and Yahnke 2006). Nothing is known of the longevity/lifespan of Bahaman funnel-eared bats.|
|Habitat and Ecology:||
This species is poorly known. It is insectivorous (Nowak, 1999). These bats are found exclusively in Bahamian dry-deciduous forests. Deep caves, where hot and moist conditions are maintained continuously, are the single most important habitat requirement. During their active hours Bahaman funnel-eared bats forage for insects in the dense understory of surrounding forests. Nothing is known of the reproduction or mating systems of Bahaman funnel-eared bats, but they are most likely polygynous. (Burns and Yahnke 2006)
Generally colonies of Bahaman funnel-eared bats leave their roost 30 minutes after sundown. Bahaman funnel-eared bats are such agile flyers that they are rarely caught in mist nets. For this reason, little is know about their natural history (Burns and Yahnke 2006).
|Major Threat(s):||Restricted to caves. Climatic changes.|
|Conservation Actions:||Protect the caves.|
