| Popis: | Rhinolophus lepidus, Blyth, 1844, (family Rhinolophidae) is one of the 124 bat species found in India. Till date, 13 species have been reported from Delhi, with one of the identified roosting site present in a natural cave in Aravalli Biodiversity Park. Roost population with direct roost count estimation and morphometric measurements of 65 individuals (49h, 16f) were studied at the said location. Roosting behavior, and emergence time for Blyth’s horseshoe bat, R. lepidus were recorded from June 2015 to September 2016. Echolocation calls were recorded during roosting and release calls during foraging. The recordings revealed a frequency with the maximum energy of 108 kHz. This study also reports the phenomenon of torpor in bats from North India in the winter season for the first time. |
