Micronycteris daviesi (Hill, 1964)
|Taxonomic Notes:||Formerly included in the monotypic genus Barticonycteris.|
|Red List Category & Criteria:||Least Concern ver 3.1|

This species is listed as Least Concern in view of its relatively wide distribution and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category. However, this species is rare and its habitat type is threatened regionally. This species seems to be locally threatened (as in Bolivia).
|Range Description:||Occurs througout Honduras south to Peru, the Guianas, Brazil, and Bolivia; Trinidad (Simmons 2005). May be present in Colombia. Range is confined to eastern flanks of the Andes. Known from 0-300 m asl (Ochoa pers. comm.), and in Ecuador up to 500 m (Pine et al. 1996).|
Native:Bolivia, Plurinational States of; Brazil; Colombia; Costa Rica; Ecuador; French Guiana; Guyana; Honduras; Panama; Peru; Suriname; Trinidad and Tobago; Venezuela, Bolivarian Republic of

|Population:||This species is relatively rare, which could be either an artifact of sampling methodology or local fluctuations in abundance. Apparently very rare and patchily distributed (Reid, 1997).|
|Habitat and Ecology:||
Forest interior species. Poorly known; probably restricted to mature, evergreen forest. Roosts in hollow trees; occasionally caught in harp traps or mist nets set across forest trails. These bats feed on large insects and occasionally fruit; they forage by gleaning large insects such as cockroaches, dragonflies, and katydids from the vegetation or ground, and they carry their prey back to a feeding roost before eating (Emmons and Feer, 1997). A small spotted frog was found in the stomach of one individual from Panama (Reid, 1997).
Has been found in secondary forested areas near primary forest (Ochoa pers. comm.), but seems to prefer primary forest. Roost in hollow trees. Record of males, females and juveniles roosting together (Solari pers. comm.). Some records of ecoparasites (Solari pers. comm.).
|Major Threat(s):||In Bolivia this species is considered vulnerable as it occurs in fragile ecosystems (montane forests and flood plains Aguirre 1998). Loss of primary forest, and reduction and fragmentation of habitat are localised threats, but there are no major threats throughout its range at present.|
|Conservation Actions:||Found in protected areas. Conservation of habitat (primary forests). The species occurs in a number of protected areas throughout its range.|
