Abstract

We tried to study the song frequency of Black paradise flycatcher and from May 1 to June 30, 2023, we got songs using songmeter at 15 sites in Geoje, Hallyeohaesang National Park. As a result, the Black paradise flycatcher was first recorded on May 10. The song frequency during the daily was the most frequent at 06:00, and the song frequency was the most active during the mid-June period. The correlation between song frequency and weather factors was analyzed. There was a positive correlation with the daily average temperature, and a negative correlation was found with precipitation and relative humidity factors. This study is meaningful in that it presents the criteria for the timing of the Black paradise flycatcher survey.
