ABSTRACT

Investigating the diversity of unprotected areas is fundamental in comprehensively understanding national bird diversity, as neglecting these smaller, often overlooked areas can lead to an incomplete portrayal of the nation's total avian population. To provide baseline information of bird diversity, abundance and richness a survey was undertaken in the Chokchisapani Community Forest in the autumn and winter months. Birds were assessed utilizing Point Count Method which revealed 59 species from 29 families and 11 orders. 24 species were recorded in the autumn season and 53 species of birds were identified in the winter season while 18 species were seen in both seasons. The diversity of species throughout two separate seasons was analyzed with the help of Shannon-Weiner Diversity Index. In comparison to the autumn season (H=2.629) (E=0.827), the winter season (H=3.3) (E=0.831) demonstrated greater bird diversity as well as evenness. Simpson’s Diversity Index Showed that winter season (SDI=0.12) had lower dominance than autumn season (SDI=0.11). Unaware utilization of forest resources is a threat to the avian diversity of the area. Involvement of villagers in decision making and management practices will ensure a healthy forest ecosystem.
