About Common Noctule Bat:

• The Common noctule (Nyctalus noctula) is an insectivorous bat.
• Appearance: Its colors range from golden to dark brown above and usually pale brown below. Their wings are narrow and pointed, and they have a characteristic powerful, direct flight, with repeated steep dives when chasing flying insects.

• Habitat:
  • They generally reside in forests but may forage in open areas and dwell in or near human habitation. Roosting sites include hollow trees, buildings, and caves.
  • During winter they hibernate in caves, rock crevices, bat boxes, or blocks of flats in Eastern Europe, where they are the most common hibernating bat species in the cities.
• Distribution: They are found in common throughout Europe, most of temperate Asia to Japan and Burma, Oman, Viet Nam, Taiwan and Algeria.
• Conservation Status
  • IUCN: Least Concern
