Abstract

Panua Sanctuary is a conservation area, known as a habitat for birds, particularly the diurnal birds. The objectives of this research are as follows to figure out the species of diurnal birds, and to know the diversity, diversity numbers, evenness, and dominance index of the diurnal birds in Panua Sanctuary. The research was conducted from February until March 2021. The point count method was employed in four observation stations. The research result revealed 10 ordos, 27 families, 50 species, and 321 total of individuals. The diversity index in station I was 0.15, station II 2.10, station III 2.34, and station IV 2.70. The diversity numbers in station I was 0.15, station II 0.36, station 0.22, and station IV 0.14. The evenness index in station I was 0.87, station II 0.79, and station III 0.8. Station I was dominated by Yellow-sided Flowerpecker with Di = 15.44% which was considered as a dominating type while station II was dominated by Yellow-breasted Racquet-tail with Di = 35.71%. Station III and IV were dominated by Cattle Egret with Di value respectively 21.62% and 14.49%.
