This species is listed as Least Concern as it is widespread, relatively tolerant to a range of habitats, and is unlikely to be declining rapidly enough to qualify under a more threatened category.

Population [top]

Population:This species is uncommon and local, but widespread (Emmons and Feer 1997). They roost either alone or in small groups of 12 or less, rarely numbering over 40 to 50 individuals (Uieda 1987). In one study, D. ecaudata was observed to be more solitary and did not gather into groups when in the presence of other bats in a cave. They have a structured society in which they build strong social bonds with other bats in the colony. Very rare in Belize (Miller pers. comm.).
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Found in all types of forest, mainly at low elevations. Roosts in caves and mines, rarely in hollow trees. Individuals are well spaced in the roost, and group size is usually small, although a group of more than 500 was found in a cave in Puebla, Mexico, where numbers were much reduced in January, perhaps indicating seasonal movements or migration. Avian blood may predominate in the diet of wild individuals, although cattle are occasionally exploited. Unlike other vampires, this attractive bat is gentle and easy to handle. Reproduction occurs year around (Reid 2009). Also occurs in open areas (Aguiar pers. comm.).

Threats [top]

Major Threat(s): There are no major threats throughout its range. There are vampire control programs.

Conservation Actions [top]

Conservation Actions: Further surveys are needed in the Amazon region to confirm the species presence or absence. As for other vampire species, education programs about vampire and rabies control programs are required. The species should be excluded from vampire control programs.
