Abstract

Bat emergence survey at Wind Cave Nature Reserve was conducted for nine days from October 20 I 4 to April 20 J 5. A total of I, 908 echolocation calls were obtained from 11 species of bats. One species, Penthetor lucasi does not emit echolocation frequency thus the survey on this species was conducted by observation only. The 11 species of insect-eating bats was Rhinolophus affinis, R. borneensis, R. luctus, Hipposideros larvatus, H. diadema, H. cervinus, H. coxi, H. galeritus, H ater, Myotis horsfieldii and M. montivagus. The most abundance echolocation call recorded was from R. affinis with 951 calls while the most abundance bats can be observed was P. lucasi. The least echolocation calls recorded was H. ater. Most of the species emerged between 1850 hour to 1950 hour. The emergence activity atarted as early as 1800 hour and last can last until 2000hour. Pairwise comparison showed that there are signifant different on the number of call between entrance I and 2, entrance 2 and 3 and entrance 1 and3.
