|Scientific Name:||Natalus tumidirostris|
|Species Authority:||Miller, 1900|
Natalus continentis Thomas, 1911
Natalus haymani Goodwin, 1959
|Taxonomic Notes:||The species can be misidentified as N. stamineus, records from northern South America may have erroneously identified as such.|
|Red List Category & Criteria:||Least Concern ver 3.1|
|Assessor/s:||Dávalos, L., Velazco, P. & Aguirre, L.|
|Reviewer/s:||Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)|
The species distribution includes well preserved areas, where it can be abundant in karst areas or where caves occur. The species is listed as Least Concern because its population is unlikely to be declining at a rate to qualify it for inclusion in any of the threat categories.
|Range Description:||This species is known from northern Colombia, Venezuela, Guyana, and French Guiana; also in Trinidad and Tobago, Curacao and Bonaire (Netherlands Antilles) (Simmons 2005). Its upper elevation range was thought to be around 548 m (Eisenberg 1989) but there are records from 1,000 m.|

|Population:||Widespread. The species is an aerial insectivore and as such under sampled by mist netting; the species is known from few specimens.|
|Habitat and Ecology:||The species tolerates both dry and wet habitats, but most specimens are encountered in dry deciduous forest (Eisenberg 1989). Occasionally found in rainforest, but more often in more arid habitats of deciduous or dry forest, and in gardens and plantations (Emmons and Feer 1997). The species feeds on insects. It roosts in the dark recesses of humid caves, where they hang singly or in groups of well-separated individuals, sometimes in colonies of thousands. They may be restricted to regions with caves and karstic environments (which are absent in much of the Amazon basin). They fly with a fluttering flight low over the ground, and use the large tail membrane to catch insects. Completely cave dependent - and to a specific cave type (Davalos and Ochoa pers. comm.).|
|Major Threat(s):||Destruction and vandalism of caves. If associated with karstic environments, it may be vulnerable. Very little known about general ecology and habits.|
|Conservation Actions:||Restricted entirely to cave habitats. Conservation of cave habitats and karstic regions is important for species. The species distribution includes well preserved areas, where it can be abundant in karstic areas or where caves occur. Its population is unlikely to be declining at a rate to qualify it for inclusion in any of the threat categories. This is one of the few bats which is completely (also morphologically) dependent on caves. Caves are also currently threatened by vampire control programs - which are non specific and kill all bats in caves. These are also fragile species and die easily.|
