  • IUCN: Listed as "Data Deficient".
  • Protection: Listed under Schedule I of the Wildlife (Protection) Act, 1972.
  • Geographical Distribution:
    • Primarily found in the Western Ghats, with a single known breeding colony.
    • Small colonies in Jaintia Hills, Meghalaya, and a solitary individual sighted in Cambodia.
  • Physical Characteristics:
  • Large in size, with huge ears extending beyond the muzzle.
  • Bicoloured velvet fur.

  • Significance of the Delhi Sighting:
  • The sighting at Yamuna Biodiversity Park is significant for Delhi, marking a rare occurrence in the region.
  • Delhi's bat species: The city is home to about 14 bat species, with four species, including the Indian false vampire and Egyptian free-tailed bat, considered locally extinct.
  • Conservation Efforts:
  • Two decades of ecological restoration have created specialized niches in the area, aiding species rewilding and ecological balance.
  • The Aravalli Biodiversity Park in Gurugram now serves as the only known roosting site for the Blyth’s horseshoe bat in Delhi NCR.
  • Additional Notes:
  • Wroughton’s free-tailed bat was considered critically endangered until 2000 due to its limited known population. However, the discovery of populations in other regions has led to a reclassification to "Data Deficient".
