A rare bat species, Tickell’s Bat (Hesperoptenus tickelli), has been rediscovered in Sri Lanka after 58 years. This remarkable finding was made by Dr. Tharaka Kusuminda, a renowned researcher from the Department of Zoology at the University of Colombo.
Previously last recorded in 1963, the species was classified as “Data Deficient” in the International Union for Conservation of Nature (IUCN) Red List. The rediscovery confirms the continued existence of this elusive species in the country.
Characteristics and Habitat
Belonging to the Vespertilionidae family, Tickell’s Bat is a small-bodied species historically observed in Sri Lanka’s dry, wet, and intermediate zones. Known for its unique behavior, these bats tend to inhabit tall trees with large leaves, concealing themselves amidst the foliage.
Discovery Locations
Recent sightings have documented three individual bats from distinct locations: Kuruwita-Ikili Gohda, Halloluwa in Kandy, and Hokandara in Colombo. This distribution highlights the species’ ability to survive across varied ecosystems despite decades without recorded observations.
Limited Data on Behavior
Due to the absence of observations for nearly six decades, little is known about Tickell’s Bat’s behavioral patterns, habitat preferences, and life cycles. However, this rediscovery offers an invaluable opportunity to explore these aspects and fill gaps in scientific understanding.
Collaborative Efforts Behind the Discovery
This significant finding was supported by a team of researchers, including Professor Emeritus Wipula Bandara Yapa, Chamara Amarasinghe, Dr. Tilakawansa Chandrathilake (University of Sri Jayewardenepura), Dr. Amani Mannakkara (University of Ruhuna), Pasindu Abeygunawardena from the Young Biologists’ Association, and others.
Importance for Biodiversity Conservation
The rediscovery is a milestone in the study of Sri Lanka’s biodiversity, especially in the field of bat research. It emphasizes the urgent need for long-term conservation efforts to protect such rare species and their habitats. By safeguarding these bats, Sri Lanka can preserve an essential part of its rich ecological heritage.
This discovery not only adds to our understanding of the island’s unique fauna but also serves as a reminder of the importance of continued research and conservation initiatives to protect endangered species.
