dc.description.abstractOwls are one of the least studying avian species because of their secretive nature. The distribution of owls was studied in Wayanad Wildlife Sanctuary (WWLS) using call playback method. Out of eight species focused by call playback; only five species responded to its conspecific call play back. Oriental scops owl (Otus sunia) responded to most of the call playback (62% response) followed by Jungle owlet (Glaucidium radiatum; 50%), Brown hawk owl (Ninox scutulata; 48%) and Indian scops owl (Otus bakkamoena; 14%). Spot bellied eagle owl (Bubo nipalensis) responded only once to its conspecific call (2.4%). On an average, the number of individual responses (n) of Oriental scops owl responded to the call playback was 2.38 ± 1.08. While the average number of individual response by Jungle owlets was 1.95± 0.97 and Brown hawk owl 1.25± 0.55 respectively. A higher chance of occurrence of Oriental scops owl was found in the dry deciduous habitat (58%) while Indian scops owl (30%) and the Jungle owlet (30%) were found high in the teak abundant habitats. Whereas species like Brown hawk owl was found higher in the forest fringe area. Spot bellied eagle owls were found only in the moist deciduous habitat when the survey was done. The study showed the importance of how the call playback method plays the role to investigate secretive, nocturnal species like owls.en_US
