Present study was focused on detennining the effective sound to deter species Lonchura Atrbpilla jagori which also known as Black-headed Munia. Few sample of sound playback have been used to test their effectiveness on scaring Black-headed Munia. Two categories of sound playback have been used in this study, which is complex sound playback and single signal sound playback. The two kinds of sound used for complex sound are high intensity sound and predator call. Whereas, high frequency single signal sounds are used from 17.0kHz until 15.0kHz. The frequency of the sound slowly reduce 0.2 kHz every 5 minutes from 17.0kHz to 15.0kHz. For complex sounds, the result showed that Black-headed Munias only give good responses to sound of siren, eagle call, and snake hiss playbacks. While for high frequency single signal sound, Munias only show good responses at 17.0 kHz. The reason might be the adaptability of Black-headed Munia to the repeated playback and hence slowly reduce their awareness to the sounds. In fact, the limited space in the cage can be another reason to explain the pattern of result.
