EXPERIMENTAL SIMPLE JUDGMENT BETWEEN EXISTENCE AND NON-EXISTENCE AND EVALUATION OF BREEDING STAGE OF GOSHAWK USING SOUND ANALYSIS

Abstract

 Raptor was surveyed frequently in various construction projects and natural environment research. The investigation of raptors needs many experienced investigators and time. Thus, in this study, we try to develop the efficient survey method of raptors (Goshawk Accipiter gentilis) using sound analysis. First, we derived Goshawk's calls from the prerecorded video by camera on nests. Second, we built discriminant model to classify Goshawk's calls to five calls (i.e., alarm, begging, copulation, chick, unfledged bird).
