The eastern bent-wing bat, (Miniopterus fuliginosus) is a species of vesper bat in the family Miniopteridae. It is found in South Asia, Far-east Asia, the east Caucasus Mountains and also in Southeast Asian regions.

Description

They exhibit long and narrow wings, high wingspans and low wing loadings, which enable quick and long flights.[1] Head and body length is 10 to 11 centimetres (3.9 to 4.3 in) and the forearms are 4 to 5 centimetres (1.6 to 2.0 in) long with a wingspan of 30 to 31 centimetres (12 to 12 in).

Color varies from reddish brown to dark blackish brown above, with the underparts being lighter. The wing membrane is blackish brown. Fur is dense and soft, long above and short below. The ears are small and the cheeks are hairless below the eyes.

A study done on echolocation on Eastern bent-wing bats showed that, "Seven of the colonies had very similar peak frequencies, while only one colony was significantly higher than the others (Zhang, et al 2018)". [2]The similarity that was seen between the seven colonies was due to "Frequent dispersal and migration (Zhang, et al 2018)".[3]

Taxonomy

This species was once considered a subspecies of the common bent-wing bat, but now it has been accepted that the eastern bent-winged bat and Australasian bent-winged bat are two separate species.[4]
