The mountain-Noctule ( Nyctalus montanus ) is a bat species from the genus of Noctule . Its distribution area is limited to the area of the Himalayas in South Asia.
features
The noctule bat reaches a body length of 6 to 6.5 centimeters with a tail of 0.5 to 0.8 centimeters in length. It is about the same size as the little noctule bat. The back fur is blackish-brown without reddish parts, the peritoneum is lighter in color. As with other noctule swifts, the wings are comparatively long and narrow. The rounded ears are bare and black.
distribution
The range of the noctule bat is limited to the area of the Himalayas in South Asia. It occurs in the Indian states of Himachal Pradesh and Uttarakhand , the provinces of Nangarhar and Paktika in Afghanistan and parts of Nepal and Pakistan .
The entire distribution area has an area of more than 20,000 km 2 , whereby the habitat used by the species is more than 2,000 km 2 . It lives here at altitudes between 680 and 1692 meters and occurs mainly in the area of rivers and dry areas.
Way of life
Little information is available about the way of life of the species. Like the little noctule it feeds on flying insects. The bat finds resting places in the rock walls, between stones and in the vegetation.
Systematics
The noctule bat is viewed as an independent species of the noctule bat (genus Nyctalus ). Until a few years ago, the animals of this species were assigned to the Asian populations of the noctule bat ( Nyctalus leisleri ) as a subspecies.
Hazard and protection
The species is rated by the International Union for Conservation of Nature and Natural Resources (IUCN) as “Least Concern” due to its relatively large distribution area and population size. Serious population decline and threats to the species are not known, although populations are in decline. The main threat to the species is estimated to be habitat loss through deforestation and conversion into agricultural land. The bat is also hunted for medical purposes.
